Kutheni i-ESS Integrated EV Charging iyikamva leeNethiwekhi ezikhawulezayo zeHlabathi

Ukuguqula Iziseko Zophuhliso: Kutheni Izikhululo Zokutshaja Ezidibeneyo Zeenkqubo Zokugcina Amandla (i-ESS) Zimela Ikamva Eliqinisekileyo LeeNethiwekhi Zokutshaja Okukhawulezayo Zehlabathi, Uzinzo Lwegridi, Ukuzimela Kwamandla, kunye Nokususwa Kwekhabhoni Ezizinzileyo Zokuhamba Kweedolophu

Intshayelelo: Isiphango Esidibanayo Sokufakelwa Kombane NeeMiqobo Zegridi

Utshintsho lwehlabathi ukuya kwizithuthi zombane (ii-EV) alusengomkhwa ongaphandle kodwa luyintsika ephambili yomgaqo-nkqubo wemozulu wamazwe ngamazwe kunye nesicwangciso semizi-mveliso. Njengoko izithuthi ze-injini yokutshaja yangaphakathi (i-ICE) zincitshiswa kancinci, imfuno yeziseko zokutshaja ezikhawulezayo nezithembekileyo inyuke kakhulu. Nangona kunjalo, olu tshintsho lujongene nomqobo omkhulu: igridi yombane endala nenqongopheleyo. Imodeli yendabuko yokutshaja kwe-EV—ukutsala amandla ngqo kwigridi xa ifuneka—iya ingabi namandla njengoko isantya sokutshaja sisuka kwi-50kW ukuya kwi-350kW nangaphezulu.

Kule meko, ukutshaja kwe-EV okudityanisiweyo kweNkqubo yoGcino lwaMandla (i-ESS) kuye kwavela kungekuphela nje njengendlela eyahlukileyo, kodwa njengemfuneko yobugcisa neyoqoqosho. Ngokudibanisa imfuno ephezulu yetshaja kumthwalo ophezulu kwigridi, izitishi ezidityanisiweyo ze-ESS zibonelela nge-buffer esombulula ingxaki ekhawulezileyo yokuxinana kwegridi ngelixa zivula imithombo emitsha yengeniso kunye nokusebenza kakuhle. Eli nqaku libonelela ngobunzulu obupheleleyo kubunjineli, uqoqosho, kunye nendlela yexesha elizayo yokutshaja okudityanisiweyo kwe-ESS, kuhlolwa ukuba kutheni olu lwakhiwo lwe-hybrid luyiplani engenakuphepheka yesizukulwana esilandelayo seziseko zamandla othutho.

Isahluko 1: Ifiziksi yokutshaja ngokukhawuleza kunye neNgxaki yeGridi ekhulayo

Umngeni woXinaniso lwaMandla

Ukuze uqonde imfuneko yokudibanisa i-ESS, umntu kufuneka aqale aqonde ubukhulu bamandla afunekayo ekutshajeni ngokukhawuleza kwanamhlanje. Indlu eqhelekileyo isebenza ngomthwalo ophezulu onokuba yi-5kW ukuya kwi-10kW. Itshaja enye ye-EV ekhawulezayo (UFC) ingafuna i-350kW—elingana nomthwalo ophezulu wezindlu ezingama-35 ukuya kuma-70. Xa ihabhu yokutshaja ifaka iiyunithi ezilishumi ezinjalo, imfuno ekhawulezileyo ifikelela kwi-3.5MW.

Kwiinethiwekhi ezininzi zokusasaza ezikhoyo, ukongeza umthwalo we-3.5MW kwindawo enye yokunxibelelana (POI) sisiganeko esibi kakhulu. Kufuna ukuphuculwa okukhulu kwiitransformers, izitishi ezincinci, kunye neentambo ze-medium-voltage. Amaxesha okukhokela kolu phuculo anokususela kwiinyanga ezili-18 ukuya kwezingama-36, kwaye iindleko zihlala ziphezulu kakhulu, zinokufikelela kwizigidi zeerandi kwindawo nganye.

Iiprofayili zoMthwalo kunye nokuShefa okuPhezulu

Imithwalo yokutshaja ye-EV idume ngokuba “yi-spike.” Isitishi sisenokungafumani mfuneko kangangeeyure ezininzi, kulandele ukunyuka okukhulu ngequbuliso njengoko izithuthi ezininzi zifika ngaxeshanye. Igridi kufuneka ibe nobukhulu obufanelekileyo kwezi ncopho zingafane zenzeke, nto leyo ekhokelela kumanani aphantsi kakhulu okusetyenziswa kweziseko ezingundoqo ezibizayo.

Ukuhlanganiswa kwe-ESS kujongana noku ngokusebenzisa "ukucheba okuphezulu." Inkqubo yebhetri itshaja kancinci nangokuthe chu ukusuka kwigridi ngexesha lemfuno ephantsi okanye ukuveliswa okuphezulu okuhlaziyekayo. Xa i-EV ingena, i-ESS ikhupha ngokukhawuleza ukuze inike ukuqhuma kombane ophezulu ofunekayo. Oku kuvumela isikhululo ukuba sinikeze ukutshaja kwe-350kW nokuba uqhagamshelo lwegridi yendawo lulinganiselwe kuphela kwi-50kW okanye i-100kW.

Ulawulo lweThermal kunye noZinzo lweVoltage

Ngaphaya komthamo olula, ukutshaja kwamandla aphezulu kwazisa imingeni ebalulekileyo kulawulo lwe-voltage. Ukutsala i-currents enkulu kwi-grid "ebuthathaka" kubangela ukwehla kwe-voltage yendawo, okunokuphazamisana nezixhobo zoshishino ezikufutshane okanye izixhobo ze-elektroniki zokuhlala. Ngaphezu koko, ukujikeleza ngokukhawuleza kwemithwalo ephezulu kubangela uxinzelelo lobushushu kwii-transformers, okukhawulezisa ukuwohloka kwazo.

Ngokudibanisa i-ESS, isikhululo sokutshaja siba ngumthwalo olawulwayo. Unxibelelwano lwe-elektroniki lwamandla phakathi kwebhetri, igridi, kunye netshaja lunokulawula ukuwohloka kwevolthi kwaye lubonelele ngenkxaso yendawo. Ngokwenyani, i-ESS isebenza "njenge-shock absorber" yegridi, ikhusela iziseko zomzimba ngelixa iqinisekisa umgangatho wenkonzo ohambelanayo kumqhubi we-EV.

Indima yeeNkqubo zokuTshaja zeMegawatt (MCS)

Njengoko sijonge ekufakweni kombane kwiilori ezinkulu, ingxaki ikhula ngokukhawuleza. Iithagethi zeMegawatt Charging System (MCS) eziza kusetyenziswa zifikelela kwi-3.75MW ngesithuthi ngasinye. Indawo yokumisa iilori eneendawo ezintlanu zeMCS iya kufuna phantse i-20MW yamandla. Ngaphandle kokugcinwa kwamandla kwindawo ethile, ukuthunyelwa kwezi zikhululo ezinjalo bekungenakwenzeka kwiindawo ezininzi ngaphandle kokwakha izitishi ezizimeleyo. Ukuhlanganiswa kwe-ESS yeyona bhulorho isebenzayo kwixesha lee-megawatt, evumela iinqwelo-moya ezinkulu ukuba zivuseleleke ngaphandle kokunciphisa indlela yamandla yengingqi.

(Ukujonga inani lamagama: ~amagama angama-750 ukuza kuthi ga ngoku. Siza kuqhubeka ngokunzulu ngakumbi kwicandelo elilandelayo.)

Isahluko 2: Uyilo lokutshaja oluDibeneyo lwe-ESS: IiTopologi eziDibeneyo ze-AC vs. iiTopologi eziDibeneyo ze-DC

Esinye sezigqibo ezibalulekileyo zobunjineli ekuyileni isikhululo sokutshaja esidibeneyo yisakhiwo sokudibanisa. Olu khetho lulawula ukusebenza kakuhle, iindleko, kunye nokwandiswa kwenkqubo. Kukho amaqela amabini eengcinga eziphambili: iinkqubo ezidityanisiweyo ze-AC kunye neenkqubo ezidityanisiweyo ze-DC.

2.1 Iinkqubo eziDibeneyo ze-AC: Indlela yeModular yeLifa

Kwisakhiwo esidityaniswe ne-AC, icandelo ngalinye—igridi, i-ESS, i-photovoltaic (PV) array, kunye neetshaja ze-EV—liqhagamshelwe kwibhasi eqhelekileyo ye-AC, ngesiqhelo kwi-400V okanye kwi-480V. Inkqubo nganye engaphantsi ifuna i-inverter okanye i-converter yayo ezinikeleyo ukuze idibane nebhasi ye-AC.

Iingenelo:

1. Ukuvuthwa:Izixhobo ze-AC zisemgangathweni kwaye zifumaneka ngokubanzi. Uninzi lweetshaja ze-EV ezikhoyo zenzelwe ukufaka i-AC, nto leyo eyenza ukudibana kwe-AC kube yeyona ndlela ilula yokulungisa iindawo ezikhoyo.
2. Ukuguquguquka:Ukongeza indawo yokugcina okanye iitshaja ezingaphezulu kulula; umane wongeza enye iyunithi kwibhasi ye-AC.
3. Ukuphinda kusetyenziswe imali:Ukuba i-ESS inverter ayisebenzi, iitshaja ze-EV zisenokutsala umbane ngqo kwigridi (ukuba uqhagamshelo lwegridi lwanele).

Iingxaki:

1. Iilahleko Zokusebenza Kakuhle:Indlela eqhelekileyo yokuba amandla elanga afikelele kwibhetri ye-EV kwinkqubo edibeneyo ye-AC ibandakanya amanyathelo amaninzi okuguqula: i-DC (iSolar) -> i-AC (i-Inverter) -> i-AC Bus -> i-DC (itshaja) -> i-DC (ibhetri ye-EV). Ukuguqulwa ngakunye kubangela ilahleko ye-2-5%, nto leyo ekhokelela ekwehleni kokusebenza okuqokelelweyo okunokudlula i-10-12%.
2. Ubunzima boVumelwano:Zonke ii-inverters kufuneka zilungelelaniswe ngokugqibeleleyo ne-AC grid frequency kunye ne-phase, zifuna isoftware yokulawula enobuchule ukuthintela i-harmonics kunye nokungazinzi.

2.2 Iinkqubo eziDibeneyo ze-DC: Ikamva eliSebenza kakuhle kakhulu

Kwisakhiwo esidityaniswe yi-DC, iitshaja ze-ESS, i-PV array, kunye ne-EV zonke ziqhagamshelwe kwibhasi ye-DC ene-voltage ephezulu (ngesiqhelo i-800V ukuya kwi-1000V). I-AC/DC converter enye enkulu ejikelezayo idibanisa i-microgrid yonke kunye nesixhobo sombane.

Iingenelo:

1. Ukusebenza kakuhle okugqwesileyo:Amandla ahamba ukusuka kwiiphaneli zelanga okanye kwi-ESS ukuya kwibhetri ye-EV ngamanyathelo amancinci okuguqula (DC -> DC). Ngokususa amanqanaba angafunekiyo e-DC-to-AC kunye ne-AC-to-DC, ukusebenza kakuhle kwenkqubo iyonke kunokuphuculwa nge-5-8% xa kuthelekiswa nokudibanisa kwe-AC.
2. Ulawulo Olulula:Akukho mfuneko yokuvumelanisa rhoqo phakathi kwezinto. Inkqubo ilawula ukuhamba kwamandla ngokulungelelanisa amanqanaba e-DC voltage, nto leyo ezinzile ngakumbi kwaye isabela ngokukhawuleza.
3. I-Figure Encinci:Ngenxa yokuba izinto ezininzi zabelana nge-inverter ephakathi, umlinganiselo opheleleyo wezinto ze-elektroniki uyancipha, nto leyo ibalulekileyo kwiindawo zasezidolophini ezixineneyo.

Iingxaki:

1. Ixabiso lokuqala eliphezulu:Ii-switchgear ze-DC ezine-voltage ephezulu kunye nee-converter ze-DC-DC okwangoku zibiza kakhulu kunee-AC.
2. Ukungabikho koMgangatho oMiselweyo:Ngelixa eli shishini lisiya kwi-DC microgrids, akukho mgangatho uphantsi kwiiprotokholi zokhuseleko kunye nokhuseleko lwe-DC xa kuthelekiswa nemigangatho ye-AC yenkulungwane.

2.3 IiTopoloji zeHybrid Microgrid

Abaphuhlisi abaphambili ngoku bajonga ii-topologies ezixubeneyo ezidibanisa ezona zibalaseleyo kuzo zombini ihlabathi. Umzekelo, isikhululo singasebenzisa ibhasi ye-DC ukuhamba kwamandla okuqala phakathi kwe-ESS, i-PV, kunye ne-UFCs, kodwa sigcine uqhagamshelo lwe-AC kwimithwalo encedisayo efana nokukhanyisa, iinkqubo zokupholisa, kunye neetshaja zeNqanaba lesi-2. Le ndlela "egxile kwi-DC" ibonwa ngokubanzi njengomgangatho wegolide kwiindawo ezisebenza kakuhle apho uxinano lwamandla kunye nokusebenza kakuhle kubaluleke kakhulu.

Isahluko 3: Uhlalutyo lwezoQoqosho: Ukunciphisa iindleko zokwandiswa kwegridi kunye nengeniso yokucheba ephakame kakhulu

Ukuphila kakuhle kwemali kwezitishi zokutshaja ze-EV kudla ngokuphazamiseka zizinto ezimbini: inkcitho ephezulu yemali (i-CAPEX) yokuphucula igridi kunye nenkcitho ephezulu yokusebenza (i-OPEX) eqhutywa "ziindleko zemfuno." Ukuhlanganiswa kwe-ESS kubonelela ngesisombululo sotyando kuzo zombini.

3.1 Ukuphepha "Umgibe Wokuguqula"

Xa umphuhlisi echonga indawo ephambili yehabhu yokutshaja—mhlawumbi indawo exakekileyo yokunqumlana komgaqo omkhulu—udla ngokufumanisa ukuba umbane wasekuhlaleni ufuna ukuphuculwa kwesitishi esingaphantsi kwe-$500,000 ukuxhasa umthwalo omtsha. Kwiimeko ezininzi, ezi ndleko zenza iprojekthi ingabi namali.

Ngokufaka i-1MWh / 500kW ESS, umphuhlisi unokuvala ukutsalwa kwegridi kwinqanaba eliphantsi kakhulu (umz., 100kW). I-ESS iphatha iziganeko zamandla aphezulu. Ukonga ekuphepheni ukuphuculwa kwegridi kunokugubungela inxalenye enkulu yexabiso le-ESS, nto leyo eyenza ibhetri "ingabi namsebenzi" ngokwembono ye-CAPEX kumjikelo wobomi beprojekthi.

3.2 Ukususa Iindleko Zemfuno

Kwiirhafu ezininzi zeenkonzo zorhwebo, inxalenye enkulu yebhili yenyanga imiselwa “yimfuno ephezulu”—umthamo ophezulu wamandla atsalwa kuyo nayiphi na isithuba semizuzu eli-15. Kwisikhululo sokutshaja se-EV, apho imfuno ingena rhoqo, iseshoni enye yokutshaja ye-350kW ehlala imizuzu engama-20 inokubangela intlawulo yemfuno yamawaka eedola, nokuba isikhululo asisebenzi inyanga yonke.

Ukuhlanganiswa kwe-ESS kwenza kube lula "ukucheba okuphezulu." Inkqubo yoLawulo lwaMandla ekrelekrele (i-EMS) ijonga umthwalo kwaye iqinisekisa ukuba ukutsalwa kwegridi akudluli umda obekiweyo. Njengoko umthwalo we-EV usanda, i-ESS inyusa ukukhutshwa kwayo ukuze igubungele umahluko. Oku kunokunciphisa iindleko zenyanga zenkonzo nge-30% ukuya kwi-60%, okuphucula kakhulu izinga langaphakathi lembuyekezo (IRR) kumqhubi.

3.3 Ulawulo lweArbitrage kunye neXesha lokusetyenziswa (TOU)

Ngaphaya kokucheba okuphezulu, i-ESS inokuzibandakanya kwi-arbitrage yamandla. Ingatshaja ukusuka kwigridi ebusuku xa amaxabiso ombane ephantsi (okanye aphantsi kwezinye iimarike ezinomoya ophezulu) kwaye ikhuphe emini ukuze inike amandla i-EV xa amaxabiso ephezulu. Le ndlela "yokuthenga ephantsi, thengisa ephezulu" yongeza olunye ungqimba lwenzuzo, iguqula isikhululo sokutshaja sibe yimpahla yokurhweba ngamandla enobuchule.

3.4 Ixabiso Lokungasebenzi

Njengoko uxinzelelo lolawulo lusanda (njengomthetho we-AFIR we-EU), abaqhubi bokutshaja banikwe igunya lokusebenzisa iziseko zophuhliso ngomlinganiselo omkhulu. Abo baxhomekeke kuphela ekutshajeni ngqo kwigridi baya kuzifumana bevalelwe kwi-OPEX ephezulu kwaye bethintelwe ngumthamo wegridi yasekuhlaleni. Isitishi esidityaniswe ne-ESS, ngokuchaseneyo, "sikhuselekile kwixesha elizayo." Njengoko imfuno yokutshaja ikhula, umqhubi unokongeza nje iimodyuli zebhetri ezingaphezulu endaweni yokucela usetyenziso ukuba luphucule igridi yesibini okanye yesithathu.

(Ukujonga inani lamagama: ~amagama ali-1800 ewonke. Ubunzulu buyanda.)

Isahluko 4: Ilanga + Ugcino + Ukutshaja (SSC) Intsebenziswano: Ukuphucula Ukusetyenziswa Okuhlaziyekayo

Eyona njongo iphambili yotshintsho lwamandla kukuhambisa amandla ngamandla acocekileyo nahlaziyekayo. Nangona kunjalo, ukungalingani phakathi kokuveliswa kwelanga kunye nokuziphatha kokutshaja kwe-EV kubangela umqobo omkhulu. Amandla elanga afikelela phezulu emini, ngelixa ukutshaja kwe-EV kudla ngokuba phezulu kusasa nangokuhlwa. Inkqubo yokugcina amandla (ESS) "likhonkco elingekhoyo" elivala lo msantsa wexesha.

4.1 Ukuthwebula "iSolar Surplus"

Kwisikhululo sokutshaja esisebenza ngamandla elanga esingenandawo yokugcina, nawaphi na amandla elanga aveliswa ngaphaya koko kutsalwa zii-EV ngoku kufuneka athunyelwe kwigridi—ngokuqhelekileyo ngamanqanaba aphantsi “okungenisa”—okanye ancitshiswe (achithwe). Nge-ESS edibeneyo, i-100% yesivuno selanga inokubanjwa. Ibhetri isebenza njengendawo yokugcina amanzi, igcina ilanga lasemini ukuze lisasazwe kwii-EV ubusuku bonke nasebusuku. Oku kwandisa izinga lokuzisebenzisa, eliyeyona ndlela inenzuzo kwezoqoqosho yokusebenzisa amandla elanga.

4.2 Ukuxakeka kwe-Buffering

Amandla elanga ayaguquguquka ngokwemvelo; ilifu elidlulayo linokubangela ukwehla ngequbuliso kokuphuma. Kwitshaja ekhawulezayo, oku kuguquguquka kuyingxaki. I-ESS ibonelela ngembuyekezo ekhawulezileyo. I-EMS (iNkqubo yoLawulo lwaMandla) inokulinganisela imithombo emithathu yamandla—i-PV, i-ESS, kunye neGrid—ngexesha langempela, iqinisekisa ukuba i-EV ifumana ukuhamba okuzinzileyo, okunamandla aphezulu nokuba lifu okanye utshintsho lwegridi. Esi siphumo “sokuthambisa” sibalulekile ekugcineni ixesha elide lenkqubo yolawulo lwebhetri ye-EV (i-BMS).

4.3 Ukuzimela Kwamandla Okwenyani kunye Nokwazi Ngaphandle Kwegridi

Kwiindawo ezikude—ezinje ngeendawo zokuphumla kwiindlela ezinkulu kwiindawo ezinabantu abambalwa okanye kwiipaki zesizwe—ukwandisa igridi kudla ngokuba nzima. Uyilo lwe-SSC luvumela ukutshaja ngokukhawuleza “ngaphandle kwegridi”. Ngokulinganisa ubungakanani be-solar array kunye ne-ESS ngokufanelekileyo, isikhululo singasebenza njengesiqithi esizixhasayo. Oku kuyitshintsha indlela yokwandisa ukwamkelwa kwe-EV kwiindawo zasemaphandleni nasentlango, ukuqinisekisa ukuba “uxinzelelo lomgama” alubathinteli abahambi ukuba bahlole ngaphaya kweekhorido zasezidolophini.

4.4 Ixabiso le-ESG kwiNdalo nakwiNkampani

Kubaqhubi beenqanawa zorhwebo kunye nabagcini beendawo, ukukwazi ukubonisa ukuba ii-EV zabo zisebenza ngezinto ezivuselelekayo kwindawo kukhuthaza kakhulu iziqinisekiso zabo zeNdalo, iNtlalo, kunye noLawulo (ESG). I-ESS ivumela isiqinisekiso "sokutshaja okuluhlaza", apho yonke i-kilowatt-hour ehanjiswayo inokulandelwa emva kwiiphaneli zelanga kwindawo. Oku kuthintela ukusetyenziswa kwamandla egridi asebenzisa ikhabhoni ngexesha lexesha elixakekileyo, okufaka isandla ngokuthe ngqo ekunciphiseni ukukhutshwa komoya kwiScope 2.

Isahluko 5: Ii-Electronics zamandla eziPhambili: Intliziyo yeHub eDibeneyo

Impumelelo yokutshaja okudityanisiweyo kwe-ESS ixhomekeke kakhulu kubuchule be-electronics yamandla. Okwangoku sibona utshintsho lwesizukulwana kwitekhnoloji ye-semiconductor kunye noyilo lwe-converter oluvumela ubuninzi bamandla aphezulu kunye neendleko eziphantsi.

5.1 Ukutshintshela kwiSilicon Carbide (SiC) kunye neGallium Nitride (GaN)

Ii-inverters zamandla zemveli zazixhomekeke kwi-IGBTs ezisekelwe kwiSilicon (Insulated-Gate Bipolar Transistors). Nangona zithembekile, ii-IGBTs zinelahleko ezinkulu zokutshintsha, ingakumbi kwiifrequensi eziphezulu. Eli shishini litshintshela ngokukhawuleza kwi-Silicon Carbide (SiC) MOSFETs. Izixhobo zeSiC zinokusebenza kwiivolthi eziphezulu kakhulu kunye namaqondo obushushu, kunye nelahleko zokutshintsha ezifikelela kwi-70% ngaphantsi kuneSilicon.

Kwitshaja edityaniswe ne-ESS, itekhnoloji ye-SiC ivumela abaguquli be-DC-DC abancinci, abakhaphukhaphu, nabasebenza kakuhle. Iifrequencies eziphezulu zokutshintsha zithetha ukuba izinto ezingasebenziyo—ii-inductors kunye nee-capacitors—zinokuba ncinci, nto leyo enciphisa ubungakanani bekhabhinethi iyonke. I-Gallium Nitride (GaN) ikwavela njengomkhuphisani weenkqubo ezincedisayo zamandla aphantsi, inikezela ngokusebenza ngcono ngakumbi kwizibonelelo zamandla zangaphakathi.

5.2 Ubuchwepheshe be-Inverter obubhekisa kwicala elinye

Kwisikhululo sanamhlanje esidityaniswe ne-ESS, i-inverter ephakathi kufuneka ibe necala elihamba kabini. Ayiguquli nje kuphela amandla egridi ye-AC abe yi-DC yebhetri kunye neetshaja kodwa inokuguqula amandla e-DC abe yi-AC ukuxhasa igridi. Olu buchule lusisiseko seenkonzo zeGrid-to-Vehicle (G2V), Vehicle-to-Grid (V2G), kunye neBattery-to-Grid (B2G).

Ii-algorithms zokulawula zezi inverters zintsonkothile kakhulu. Kufuneka ziphendule kwii-milliseconds kutshintsho lwegridi, zilawule "iMeko yokuTshaja" (iSoC) ye-ESS ukuqinisekisa ukuba ixesha lihlala ixesha elide, kwaye zibeke phambili ukutshaja kwe-EV ngelixa ngaxeshanye zizalisekisa iikhontrakthi zenkonzo yegridi.

5.3 IiTopoloji zoGuquli oluneZinga ezininzi

Ukuze kusingathwe ii-voltage eziphezulu (800V-1000V) ezifunekayo kwii-EV zanamhlanje ezifana nePorsche Taycan okanye iHyundai Ioniq 5, iinjineli zisebenzisa ii-topologies ze-converter zamanqanaba amaninzi (ezifana neNeutral Point Clamped – NPC). Ezi zakhiwo zinciphisa uxinzelelo lwe-voltage kwii-semiconductors zodwa kwaye ziphucula umgangatho we-output waveform, zinciphisa ukuphazamiseka kwe-electromagnetic (EMI) kwaye ziphucula ukuthembeka kwenkqubo iyonke.

5.4 Ukupholisa Ulwelo vs. Umoya Ophoqelekileyo

Njengoko amanqanaba ombane enyuka, ulawulo lobushushu luba yingxaki enkulu. Nangona ukupholisa umoya kungabizi kakhulu, akwanelanga ukusebenza rhoqo kwe-350kW+. Izitishi ezidibeneyo eziphambili ngoku zisebenzisa iinkqubo zokupholisa ulwelo ezivaliweyo kuzo zombini iimodyuli zebhetri ze-ESS kunye ne-elektroniki yamandla. Ukupholisa ulwelo kuvumela uyilo oluncinci ngakumbi kwaye kwenza isikhululo sisebenze ngamandla apheleleyo nokuba kumaqondo obushushu aphezulu (umz., 45°C+), indawo eqhelekileyo yokusilela kwiiyunithi zokutshaja ezipholileyo zomoya ezindala.

(Ukujonga inani lamagama: ~amagama angama-2900 ewonke. Siphakathi apho.)

Isahluko 6: Imbuyekezo yoMbane oSebenzayo kunye noZinzo lweGridi kwiiHubs eziNamandla aphezulu

Nangona uninzi lweengxoxo malunga nokutshaja kwe-EV zigxile “kumandla asebenzayo” (ii-kilowatts ezitshaja ibhetri), “amandla asebenzayo” (alinganiswa nge-kVAR) abaluleke ngokulinganayo kwimpilo yegridi yombane. Izitishi zokutshaja ezinamandla aphezulu, ingakumbi ezo zinezixhobo ezininzi zokuguqula amandla ze-elektroniki, zinokuchaphazela kakhulu umgangatho wamandla wenethiwekhi yosasazo lwengingqi.

6.1 Ingxaki yePower Factor kunye neHarmonics

Ii-power electronic converters, ngokwemvelo yazo, azinazo imithwalo ethe ngqo. Ngaphandle kolawulo olufanelekileyo, zinokuzisa ukuphambuka okukhulu kwe-harmonic kunye ne-power factor embi. I-power factor embi (apho i-current kunye ne-voltage zingaphandle kwesigaba) zikhokelela ekungasebenzi kakuhle kwi-grid, nto leyo ebangela ukugqithisa kakhulu kwiintambo kunye nee-transformers kwaye ifune ukuba i-utility ivelise amandla angaphezu kwalawo asetyenziswa ngokwenene.

Izitishi ze-ESS ezidibeneyo zisebenza njengesixhobo esinamandla "soLawulo loMgangatho waMandla." Ii-inverters ezibhekisa kwicala elinye ezisetyenziswa kwezi nkqubo ziyakwazi ukusebenza nge-four-quadrant, oko kuthetha ukuba zinokulawula ngokuzimeleyo ukuhamba kwamandla asebenzayo kunye nasebenzayo.

6.2 Imbuyekezo yamandla asebenzayo (uLawulo lweVolt-VAR)

Izitishi ezidibeneyo zanamhlanje zingasebenza njenge "Static Synchronous Compensators" (STATCOMs). Ngokufaka okanye ukufunxa amandla asebenzayo (ii-VAR), isitishi sinokulawula ngamandla i-grid yengingqi. Ukuba i-voltage iyehla ngenxa yomthwalo onzima, i-ESS inverter inokufaka amandla asebenzayo "akhokelayo" ukunyusa i-voltage. Ngokwahlukileyo koko, ukuba i-voltage iphezulu kakhulu, inokufunxa amandla asebenzayo.

Olu buchule lubaluleke kakhulu kubaqhubi begridi. Kwimimandla emininzi, iinkonzo ziqala ukuhlawula abasebenzi bezikhululo zokutshaja ngezi "nkonzo zincedisayo." Isikhululo esidityaniswe ne-ESS asisasebenzisi umbane nje kuphela; sisixhobo esizinzisa igridi esinceda isikhululo silawule ubunzima benkqubo yamandla esasazwe ngokwe-intanethi.

6.3 Ukunciphisa i-Voltage Flicker kunye ne-Sags

Ukutshaja kwe-EV enamandla aphezulu kubandakanya utshintsho olukhawulezileyo lomthwalo. Xa iseshoni ye-350kW iqala okanye iyeka ngequbuliso, inokubangela "ukufiphala kwe-voltage" - utshintsho olubonakalayo ekukhanyeni kunye nomonakalo onokubakho kwii-elektroniki ezibuthathaka kwizakhiwo ezikufutshane. I-ESS isebenza njenge-buffer, inyusa umthwalo wegridi phezulu okanye ezantsi kancinci ngelixa inika impendulo efunekayo ngesantya esiphezulu kwi-EV. Oku kuqinisekisa ukuba i-transformer yosasazo lwendawo ibona iprofayili yomthwalo egudileyo, eqikelelwayo, yandisa ubomi bayo bokusebenza kwaye inciphisa iindleko zokugcinwa kwesixhobo.

Isahluko 7: I-V2G (Isithuthi ukuya kwiGrid) kwii-ESS Hubs: Indlela eSebenzayo eya kwiZityalo zoMbane eziSebenzayo (i-VPP)

Itekhnoloji yeVehicle-to-Grid (V2G), evumela ii-EV ukuba zibuyisele amandla kwigrid, idla ngokubizwa ngokuba sisisombululo esiguqukayo sokugcina igrid. Nangona kunjalo, ukusebenzisa i-V2G kwinqanaba eliphezulu kujongana nemiqobo ebalulekileyo yobugcisa neyengqondo. Ii-hubs ezidityanisiweyo ze-ESS zibonelela "ngomlamli" ofanelekileyo we-V2G ukuba ibe yinyani.

7.1 "Isiphumo seBuffer": i-ESS njenge-V2G Aggregator

Enye yezona zinto zixhalabisayo nge-V2G yimpembelelo ekuwohlokeni kwebhetri ye-EV. Abaqhubi badla ngokuthandabuza ukuvumela ibhetri yesithuthi sabo ukuba ibhayisekile ukuze ixhase igridi. Kwisikhululo esidityaniswe ne-ESS, ibhetri engashukumiyo ithatha "ukubetha kokuqala."

I-ESS inokusingatha imisebenzi yokuzinzisa igridi ephindaphindayo, ngelixa ii-EV eziqhagamshelweyo zibonelela ngombane kuphela ngexesha leziganeko eziqatha kakhulu okanye ukucima kwegridi ixesha elide. Le ndlela "yokugcina ngokwenqanaba" inciphisa ukujikeleza kweebhetri ze-EV, okwenza esi siphakamiso sibe nomtsalane ngakumbi kumnini wesithuthi.

7.2 IiProtokholi zoNxibelelwano: ISO 15118-20 kunye ne-OCPP 2.0.1

Ukuze i-V2G isebenze, isithuthi, itshaja, i-ESS, kunye negridi kufuneka zonke zithethe ulwimi olunye. Eli shishini lihambelana nomgangatho we-ISO 15118-20, ochaza unxibelelwano phakathi kwe-EV kunye neSitishi sokutshaja ukuze kubekho ukuhamba kwamandla okuhamba kwicala ngalinye.

Kwangaxeshanye, i-Open Charge Point Protocol (OCPP) version 2.0.1 ivumela inkqubo yolawulo oluphambili ukuba ilungelelanise ukuhamba kwamandla phakathi kwegridi, i-ESS, kunye nezithuthi. Ukusebenzisa ezi protocols zintsonkothileyo kulula kakhulu kwindawo edibeneyo apho umlawuli we-ESS esebenza njengengqondo ephakathi, eququzelela iiasethi ezahlukeneyo kwimpendulo enye edibeneyo.

7.3 Iimeko zokusetyenziswa kwe-V2G kwi-ESS Hubs

Khawuthelekelele indawo yokuhambisa izinto apho iiveni ezingama-50 zokuhambisa umbane zibuya khona ekupheleni kosuku. Umthamo wazo webhetri uwonke unokuba yi-4,000kWh. Endaweni yokuhlala nje ungenzi nto, ezi veni zinokufakwa kwisikhululo esidityaniswe ne-ESS.

Ngexesha lobuninzi bangokuhlwa (umz., ukusuka ngo-6 ukuya ku-9 emva kwemini), isikhululo singafumana umbane kwi-ESS ekwindawo kunye neeveni ezixhunyiweyo ukuze zibonelele ngegridi, nto leyo efumana ingeniso enkulu. Ngo-4 AM, igridi ingaphezulu, kwaye isikhululo sigcwalisa zonke iiveni kunye ne-ESS yaso, siqinisekisa ukuba iinqwelo zilungele utshintsho lwasekuseni. Olu hlobo lwe-"Virtual Power Plant" (VPP) luguqula iinqwelo-mafutha zibe yindawo yokugcina amandla eqhinga.

7.4 Ukoyisa Umqobo “wokuXhumana”

Umqobo omkhulu kwi-V2G kukoyika kwenkampani “ukutya okungalawulwayo.” Iinkampani zixhalabile ngamakhulu eemoto ezifaka umbane kwigridi. Isikhululo esidityaniswe ne-ESS senza oku kube lula ngokubonelela nge-POI enye, elawulwayo (iPoint of Interconnection). Inkampani kufuneka ithembe kuphela umlawuli ophakathi wesikhululo, osebenza njengesango kunye nodonga lomlilo, ukuqinisekisa ukuba onke amandla abuyiselwa kwigridi ahlangabezana nemigangatho yokhuseleko engqongqo kunye nomgangatho.

Isahluko 8: Ukuzimela Kwamandla Nokuqina Kwabasebenzi Bezorhwebo Nemizi-mveliso (C&I)

Kumashishini orhwebo, ababoneleli ngezothutho, kunye nezakhiwo zoshishino, ukutshintshela kwi-EVs akusiyonto nje enxulumene nokusingqongileyo; lutshintsho olubalulekileyo kwiprofayili yabo yomngcipheko wokusebenza. Njengoko iinqwelomoya ziba ngombane ngokupheleleyo, ukucima kombane akusekho yingxaki nje encinci—kukucima ngokupheleleyo kweshishini. Ukutshaja okudityaniswe ne-ESS kubonelela "ngoKunyamezela Amandla" okufunekayo ngaba baqhubi.

8.1 “Isikhululo Sokufaka Ipetroli” Esingasoze Sivalwe

Ngokungafaniyo nezikhululo zepetroli zemveli, ezixhomekeke kwigrid ukuqhuba iipompo zazo kodwa zineejenereyitha ezincedisayo, izikhululo ezininzi zokutshaja ii-EV azikwazi kwaphela xa kucinywa umbane. Kwinkampani yezothutho efana ne-DHL okanye i-FedEx, nokuba kucinywe iiyure ezimbini ngexesha lokutshaja ebusuku kunokulibazisa amawaka eempahla ezithunyelwayo.

Ihabhu edityanisiweyo ye-ESS inokusebenza "kwimo yesiqithi." Ngexesha lokusilela kwegridi, inkqubo iyaqhawula ngokuzenzekelayo kwisixhobo kwaye iqhubeke nokunika amandla iitshaja isebenzisa amandla agciniweyo kwi-ESS kunye nokuveliswa okuqhubekayo kwiiphaneli zelanga ezikwindawo. Oku kuqinisekisa ukuba izithuthi ezibalulekileyo zisoloko zitshajwa, nto leyo ebonelela ngenqanaba lokuthembeka elihambelana okanye elidlula amafutha emveli.

8.2 IiMicrogrid: Ukwakha iSiqithi saMandla aZimeleyo

Izitishi zokutshaja ezidityanisiweyo zezona zinto zibalulekileyo zokwakha "iiMicrogrids zoRhwebo." Ngaphandle kwee-EV zokutshaja, i-ESS inokubonelela ngombane oxhasayo kuyo yonke indawo—ukukhanyisa izibane, iiseva, kunye noomatshini bemizi-mveliso. Le nkonzo ineenjongo ezininzi iphucula kakhulu i-ROI yotyalo-mali lwe-ESS.

Ngokudibanisa ukutshaja kwe-EV kwisicwangciso esibanzi samandla esixhobo, iinkampani zinokufikelela "kwi-Energy Independence," zinciphise ukuthembela kwazo kwimarike yeenkonzo eziguquguqukayo kwaye zizikhusele kwiindleko ezikhulayo kunye nokuncipha kokuthembeka kwegridi yoluntu endala.

8.3 Ukukhusela Ukuguquguquka Kwamaxabiso Amandla

Imarike yamandla iya isiba mandundu ngenxa yeemeko zezopolitiko kunye nokuguquguquka okuqhelekileyo kwezinto ezivuselelekayo. Ishishini elixhomekeke kuphela kwigridi yezithuthi zalo ze-EV lijongene ne-100% yale mngcipheko wamaxabiso.

I-ESS isebenza njenge-"Physical Hedge." Ngokugcina amandla xa engabizi kwaye uwasebenzise xa ixabiso legridi linyuka, umqhubi unokulungisa iindleko zakhe zokufutha ixesha elide. Kwiimeko ezininzi, "ixabiso lamandla elilinganisiweyo" (LCOE) lesitishi esidityaniswe ne-ESS linokuqikelelwa ngakumbi kwaye liphantsi kunerhafu yegridi ephakathi, nto leyo ebonelela ngenzuzo yokukhuphisana kwimarike.

Isahluko 9: Iinkqubo zoLawulo lwaMandla eziqhutywa yiDatha (EMS): Ubuchopho beSitishi

Isikhululo sokutshaja esidityaniswe ne-ESS sisixhobo esintsonkothileyo sokulungelelanisa ukuhamba kwamandla amaninzi. Ukulawula oku kuhamba ngesandla akunakwenzeka; impumelelo ixhomekeke kwiiNkqubo zoLawulo lwaMandla (EMS) ezintsonkothileyo neziqhutywa yi-AI.

9.1 Uqikelelo loMthwalo oluQikelelweyo

I-EMS isebenzisa ii-algorithms zokufunda koomatshini (ML) ukuqikelela imfuno yokutshaja kwixesha elizayo. Ngokuhlalutya iipateni zokusetyenziswa kwembali, idatha yendlela yengingqi, uqikelelo lwemozulu, kwaneshedyuli yokusebenza kweenqwelo-moya ezikufutshane, i-EMS inokuqikelela ukuba imfuno iyanda nini.

Emva koko ilungiselela i-ESS ngokuyitshaja kwangaphambili kwiiyure zangaphambili zesidingo esiphantsi. Olu buchule be-"Look-Ahead" luqinisekisa ukuba isikhululo sihlala sikulungele iziganeko eziphezulu ngelixa sinciphisa iindleko zamandla asetyenziselwa ukuzalisa ibhetri.

9.2 Ukuphucula ii-Asethi ezininzi ngexesha langempela

Kwi-millisecond nganye, i-EMS kufuneka igqibe: ngaba amandla elanga kufuneka aye kwi-EV, kwibhetri, okanye kwigridi? Ngaba ibhetri kufuneka iphume ngoku ukuze inciphise incochoyi, okanye ilinde incochoyi ephezulu nangakumbi eqikelelwayo ukuba iza kwenzeka kamva kuloo yure?

Iiplatifomu ze-EMS eziphambili zisebenzisa "iModel Predictive Control" (MPC) ukusombulula ezi ngxaki zokulungisa izinto ezahlukeneyo ngexesha langempela. Injongo kukwandisa "iStacking of Value" - ukuqinisekisa ukuba inkqubo ibamba yonke ipesenti yengeniso evela ekuchebeni okuphezulu, i-arbitrage, iinkonzo zegridi, kunye nokusetyenziswa kwelanga kwindawo ngaxeshanye.

9.3 Ukugcinwa Okuxeliweyo kunye namawele edijithali

Ii-elektroniki ezinamandla aphezulu kunye neenkqubo zebhetri ezinkulu zisengozini yoxinzelelo lobushushu kunye nokuwohloka. I-EMS yanamhlanje idala "iDigital Twin" yesitishi sonke. Ngokujonga amawaka amanqaku edatha—ubushushu, i-voltage yeseli, i-switching frequency, kunye nokufuma—inkqubo inokubona izinto ezingaqhelekanga ngaphambi kokuba zikhokelele ekungasebenzini.

Ukuba i-EMS ifumanisa ukuba imodyuli ethile yebhetri isebenza ngobushushu obuncinci kunezinye, inokunciphisa ngokuzenzekelayo umthwalo kuloo modyuli kwaye ixelele ingcali ngokugcinwa kokuthintela. Le ndlela "yeZero-Downtime" ibalulekile kwiinethiwekhi zokutshaja zikawonke-wonke ezisetyenziswa kakhulu apho ukuthembeka kukuqhuba ukuthembeka kwabathengi.

9.4 Ulungelelwaniso lweeNqwelo-mafutha eziSemafini

Kwabaqhubi beemoto, i-EMS kwisikhululo sokutshaja ingadityaniswa nesoftware yabo ye-telematics kunye neyokucwangcisa indlela. Xa ilori yokuhambisa ikwiikhilomitha ezingama-20 ukusuka apho, isikhululo sele siyayazi i-SoC yaso yangoku, indlela yaso eseleyo yosuku, kunye nexesha layo lokutshaja elifunekayo.

I-EMS “inokubhukisha” ubungakanani obuthile bomthamo we-ESS ukuqinisekisa ukuba ilori inokutshajwa ngokukhawuleza xa ifika, ngaphandle kokubangela intlawulo yemfuno yegridi. Olu manyano lungenamthungo phakathi kwedatha yezothutho kunye namandla luphawu lwexesha “leSmart City”.

(Ukujonga inani lamagama: ~amagama angama-5100 ewonke. Uxinzelelo lokugqibela olunye kumagama okugqibela angaphezu kwama-900.)

Isahluko 10: Ukwenziwa kwezemali: Ukwenza imali ngokunciphisa iCarbon kunye neeNkonzo ezincedisayo

Njengoko ubuchwepheshe bukhula, "iMveliso" yesikhululo sokutshaja esidityaniswe ne-ESS ayisengombane nje kuphela; yipotifoliyo yeeasethi zemali nezokusingqongileyo. Ukukwazi "ukuxhasa ngemali" iziphumo ezahlukeneyo zesikhululo yikona okusiguqula ukusuka kwiziko leendleko ukuya kwiasethi yeziseko zophuhliso ezivelisa isivuno esiphezulu.

10.1 Iikhredithi zeKhabhoni kunye neMarike ye-LCFS

Kwimimandla emininzi, efana neCalifornia ene-Low Carbon Fuel Standard (LCFS), isenzo sokususa amafutha efosili ngombane senza iikhredithi ezixabisekileyo. Nangona kunjalo, ixabiso lala makhredithi lixhomekeke kubunzulu bekhabhoni (CI) yombane osetyenzisiweyo.

Isitishi esitsala umbane kwigridi ebusuku (xa izitishi zamalahle okanye zegesi zisenokuba zisebenza) sifumana iikhredithi ezimbalwa kunesitishi esisebenzisa i-solar kunye ne-ESS kwindawo leyo ukuhambisa amandla "ayi-Zero-CI". Ngokusebenzisa i-ESS ukuphucula ixesha kunye nomthombo wamandla aziswa kwi-EV, abaqhubi banokunyusa kakhulu ubungakanani kunye nexabiso leekredithi zekhabhoni abazivelisayo. Ezi khredithi zihlala zibonelela ngomthombo wengeniso wesibini ogubungela i-10% ukuya kwi-20% yeendleko zokusebenza zizonke zesitishi.

10.2 Izatifikethi zamandla avuselelekayo (ii-REC) kunye nokuphuculwa kwe-PPA

Kwizikhululo ezinkulu, uluhlu lwelanga olukwindawo lusenokunganeli ukugubungela zonke iimfuno zokutshaja. Abaqhubi badla ngokungena kwiZivumelwano zokuThenga umbane (ii-PPA) neefama zomoya okanye zelanga ezingaphandle kwendawo. I-ESS ivumela umqhubi ukuba avumelanise ukusetyenziswa kwamandla akhe neprofayili yemveliso ye-PPA yakhe.

Ngokufanisa ii-“Bundled” RECs nexesha langempela lokutshaja, umqhubi unokubonelela ngokutshaja “24/7 CFE” (Carbon-Free Energy). Oku kufunwa kakhulu ngabathengi beenkampani abazibophelele kwiSayensi eSekelwe kwiTargets (SBTi) kwaye kufuneka babonakalise ukuba imisebenzi yabo yezothutho ayisebenzi ngokupheleleyo.

10.3 Iinkonzo zeGrid: i-FCR, i-FRR, kunye neMpendulo yeMfuno

Igridi yombane ifuna ukulinganisela rhoqo, okwesibini ngesibini kokunikezelwa kunye nemfuno. I-“Frequency Containment Reserve” (FCR) kunye ne-“Frequency Restoration Reserve” (FRR) ziinkonzo ezixabisa kakhulu ezihlawulelwa ziinkonzo zombane.

Isitishi esidityaniswe ne-ESS, esine-electronics yaso enamandla akhawulezayo, sisixhobo esifanelekileyo kwezi nkonzo. Ibhetri ingaphendula ngaphantsi kwe-100 milliseconds kwi-grid frequency drop, ifaka amandla ukuzinzisa inkqubo. Ngenxa yokuba ezi ziganeko zegrid zihlala zifutshane (imizuzwana ukuya kwimizuzu), aziphazamisi kakhulu umsebenzi ophambili wokutshaja ii-EV. Olu "Value Stacking" luvumela i-ESS ukuba ifumane ingeniso nokuba akukho zimoto zixhunyiweyo, nto leyo exhasa ngempumelelo iindleko zesiseko sokutshaja.

10.4 Iimali zeZiseko zoPhuhliso kunye neeBond eziLungileyo

Ingeniso yexesha elide neqikelelweyo evela ekutshajweni okudityanisiweyo yi-ESS (ukudibanisa iifizi zokutshaja, iinkonzo zegridi, kunye neekhredithi zekhabhoni) zenza ezi zikhululo zibe nomtsalane kubatyali-mali beziko. Sibona utshintsho oluvela kwi-venture capital ukuya kwi-"Infrastructure Funding."

Abaphuhlisi ngoku bakhupha "iiGreen Bonds" ukuxhasa ukusasazwa kwenethiwekhi ezinkulu zee-hubs ezidibeneyo. I-ESS yeyona nto iphambili kolu tshintsho lwezemali, njengoko inciphisa ukuguquguquka kwengeniso yesitishi kwaye ibonelela "ngeenethiwekhi zokhuseleko" ezininzi (imijelo yengeniso) ezikhusela isiseko somtyali-mali.

Isahluko 11: Uphuhliso Lwexesha Elizayo: Ukusuka kwi-350kW ukuya kwiMegawatt Ukutshaja nangaphezulu

Ukujonga phambili, ukuhlanganiswa kwe-ESS kunye nokutshaja kwe-EV kuya kuba nzima ngakumbi njengoko ubuchwepheshe obutsha bungena kwizixhobo eziphambili.

11.1 Ukutshintshela kwiibhetri zeSolid-State

Iinkqubo ze-ESS zangoku zisebenzisa ikakhulu iikhemikhali zeLithium-Iron Phosphate (LFP) okanye zeNickel-Manganese-Cobalt (NMC). Nangona zisebenza kakuhle, zinemida ngokubhekiselele kubuninzi bamandla kunye nokhuseleko lomlilo. Isizukulwana esilandelayo see-hubs ezidibeneyo sinokusebenzisa "iiBattery zeSolid-State" (ii-SSB).

Ii-SSB zibonelela ngoxinano olukhulu lwamandla, nto leyo evumela ukuba kubekho amandla amakhulu okugcina izinto kwindawo efanayo. Okubaluleke ngakumbi, azitshi ngokwemvelo, nto leyo eyenza kube lula ukufumana imvume nokhuseleko kwizikhululo ezikwiindawo ezixineneyo zasezidolophini okanye kwiigaraji zokupaka ezingaphantsi komhlaba.

Ukusetyenziswa kwebhetri yoBomi beSibini 11.2

Njengoko isizukulwana sokuqala seebhetri ze-EV sifikelela esiphelweni sobomi baso obusebenzisekayo kwizithuthi (ngesiqhelo xa umthamo wehla uye kwi-70-80%), ezi bhetri zisenexabiso elibalulekileyo lokugcina izinto zingashukumi.

Izitishi zokutshaja ezidityaniswe ne-ESS zezona zifanelekileyo kwiibhetri "zobomi besibini". Iimfuno eziphantsi zoxinano lwamandla kwisicelo esingashukumiyo zithetha ukuba ibhetri ye-EV "ethathe umhlala-phantsi" isenokubonelela ngenkonzo yeminyaka emi-5 ukuya kweli-10 njengesikhuseli setshaja ekhawulezayo. Le ndlela yoqoqosho olujikelezayo inciphisa kakhulu umngcipheko wokusingqongileyo we-ESS kwaye yehlisa iindleko zokugcina zomsebenzisi.

11.3 Iikhorido zeDC ezineVolthi ephezulu

Sele sibona uvavanyo lokuqala nge-“DC Corridors”—iintambo ze-DC ezine-voltage ephezulu ezidibanisa izitishi ezininzi zokutshaja kunye neendawo zamandla avuselelekayo ngaphandle kokudlula kwi-AC grid. Kulo mbono, isikhululo esidityaniswe ne-ESS asiyo-node kwi-grid kuphela, kodwa yi-node kwi-“Energy Superhighway” ezinikeleyo nesebenza kakuhle. Olu lwakhiwo luza kuphelisa phantse ilahleko zokuguqulwa kwaye luvumele ukuhanjiswa kwamandla amaninzi avuselelekayo ngqo kwicandelo lezothutho.

Isiphelo: Ingxoxo yokutshaja kwe-EV edityanisiweyo ne-ESS ayiseyonto yethiyori - yizibalo. Yonke inethiwekhi yokutshaja ngokukhawuleza ehlabathini ijongene nemida emithathu efanayo: amandla oqhagamshelo lwegridi, iindleko zemfuno, kunye nokusetyenziswa. Isitishi esidityanisiweyo ne-ESS sijongana nazo zontathu ngaxeshanye, yiyo loo nto imodeli isuka "kwikamva lokutshaja ngokukhawuleza" iye "kuyilo oluzenzekelayo lweendawo ezintsha."

Kutheni Ukuhlanganiswa Kuphumelela
