I-Bottleneck yeGrid: Kutheni iiProjekthi zokutshaja ezinamandla aphezulu zingavumi

Umqhubi weenqwelo moya emazantsi eJamani wayefuna iitshaja ezikhawulezayo ze-12 × 180 kW DC kwindawo yokugcina izinto. Uphononongo lwezixhobo lubuye nenombolo eqinileyo: i-transformer ekhoyo ye-630 kVA yayinokuxhasa kuphela i-400 kW yomthwalo owongezelelweyo ngaphandle kokuqinisa. Ixabiso lokuphucula yayiyi-€180,000 ngexesha lokunikezelwa kweenkonzo leenyanga ezili-14. Umqhubi wayeneendlela ezimbini: ukunciphisa iprojekthi ibe ziitshaja ezine, okanye ukufumana indlela yokwenza igridi isebenze nzima.

Loo mqhubi akangomntu ungaqhelekanga. Kuyo yonke iYurophu, eMntla Melika, naseAsia-Pacific, iinethiwekhi zokusasaza zenzelwe imithwalo yezindlu neyorhwebo elula, kungekhona amaqela ezithuthi ezitsala i-150-600 kW nganye. Abaqhubi beenkqubo zokusasaza (ii-DSO) eJamani kuphela baxela ukusilela kwemigca yeminyaka emininzi yoqhagamshelo lwezorhwebo, kwaye izifundo ezenziwa ngabalawuli begridi yesizwe zichonga ngokuphindaphindiweyo ukutshaja ngokukhawuleza koluntu njengenye yezona mithombo mikhulu yemithwalo emitsha ukuya kuthi ga ngo-2030. Ifiziksi ilula: amandla okutshaja kufuneka avela ndaweni ithile, kwaye uqhagamshelo lwegridi ngumbhobho obonakalayo.

Isiphumo kukuba umthamo wegridi, hayi ukufumaneka kwetshaja, ngoku kumisela ukuba iprojekthi inokwenzeka na. Imida emithathu yolwakhiwo ilawula:

1. Imida yeTransformer kunye nefeeder— i-substation yasekuhlaleni okanye i-pad-mount transformer inomlinganiselo womthamo oqinileyo; ukuyidlula kuyaphazamisa izixhobo zokukhusela okanye kuyawuthoba ubomi bempahla. 2.Iindleko zoqhagamshelo kunye nokuqinisa— ukuphuculwa kweenkonzo zikagesi kufuna imali eninzi kwaye kudla ngokuhlawuliswa yonke imali kumfaki-sicelo. 3.Amaxesha okukhokela unxibelelwano— izifundo, iimvume, kunye nemigca yokwakha zihlala zityhala iiprojekthi iinyanga ezili-12-24 ngaphaya komhla wokuhanjiswa kweetshaja.

Indlela iSitishi sokutshaja seBESS esisusa ngayo isilingi somthamo

Isikhululo sokutshaja se-BESS sifaka ibhetri phakathi koqhagamshelo lwegridi kunye nezixhobo zokutshaja. Ngexesha leeyure ezingezizo ezongxamiseko — ngesiqhelo ebusuku, okanye emini kwiigridi ezisebenzisa amandla elanga — ibhetri itshaja kwigridi ngesantya esiphantsi nesizinzileyo. Ngexesha leziganeko zokutshaja, ibhetri iphuma ngaxeshanye negridi, ngoko ke isikhululo sinokuhambisa amandla okutshaja angama-240 kW okanye ama-480 kW ngelixa uqhagamshelo lwegridi lutsala kuphela i-100–150 kW.

Olu lwakhiwo lutshintsha i-equation yeprojekthi ngeendlela ezine ezilinganiswayo:

• Ukunciphisa ubungakanani boqhagamshelo.Indawo efuna ukutshaja okungama-600 kW ngaxeshanye inokubonelelwa ngoqhagamshelo lwegridi engama-200 kW kunye nebhetri engama-400 kWh–1 MWh, kuxhomekeke kwiiprofayili zeseshoni.
• Ukulibaziseka kwetransformer.Ukuba i-transformer ekhoyo inokuthwala umthwalo oqhelekileyo kodwa ingawuthwali umthwalo ophakamileyo, indawo yokugcina ifunxa umthwalo ophakamileyo kwaye akukho mfuneko yokuphucula.
• Ukuncitshiswa kweentlawulo zemfuno.Iirhafu zorhwebo zihlawula imfuno ephezulu kwisithuba semizuzu eli-15; ibhetri echeba ezo ncochoyi iyayinciphisa ngokuthe ngqo into yomgca wentlawulo yemfuno.
• Ukunyamezela.Ngexesha lokucima kwegridi, isikhululo sinokusebenza kwimo yesiqithi kwaye siqhubeke nokutshaja kumandla agciniweyo - izithuthi ezinamandla kunye nabaqhubi beempendulo zongxamiseko abaya befuna ngakumbi.

Uyilo lwe-DC-Coupled vs AC-Coupled

Ukusebenza kakuhle kwesikhululo sokutshaja seBESS kuxhomekeke kakhulu kwindlela ibhetri eqhagamshelwe ngayo:

Iinkqubo ezidityaniswe ne-DC ziguqula amandla kube kanye, zisusa ukulahleka kokuguqulwa kabini kwezakhiwo ezidityaniswe ne-AC. Ipesenti nganye yokusebenza ibalulekile kwisikali seenqwelo-moya: isikhululo esiqhuba ngebhayisekile i-1,000 kWh ngosuku silahlekelwa malunga ne-3,650 kWh ngonyaka kwindawo nganye yokusebenza elahlekileyo - exabisa amawaka eedola kumaxabiso ombane orhwebo.

Ukulinganisa ibhetri: Ukufanisa indawo yokugcina kunye nemfuno

Akukho bukhulu beBESS obuqhelekileyo, kodwa indlela yokulinganisa ubungakanani ekhuselweyo ikhona. Indawo yokuqala yiprofayili yeseshini yokutshaja: zingaphi iimoto ezifikayo, ngamandla angakanani, kwaye ixesha elingakanani. Ibhetri kufuneka igubungele umahluko phakathi kwemfuno ephezulu kunye nesivalo segridi, esigcinwe kwifestile embi kakhulu.

Abaqhubi kufuneka balinganisele ubungakanani bosuku lwe-95th percentile, hayi usuku oluqhelekileyo, kwaye bashiye indawo yokukhula kweenqwelo-mafutha kwixesha elizayo. Ulawulo lwesoftware oluqikelela ukufika kunye nemeko yokutshaja (i-SOC) lunokunciphisa amandla ebhetri afunekayo nge-15–30% xa kuthelekiswa nolawulo olusekelwe kwimithetho.

Ngaphaya koMgangatho: Imithombo yeNgeniso yesibini

Xa ibhetri ikhona, inokufumana imali ngaphandle kokuvula iitshaja:

• Ukunciphisa iindleko zemfuno— ngokwesiqhelo lolona longelo lunye lukhulu, oludla ngokuba yi-30–70% yesabelo semfuno yebhili yorhwebo.
• I-TOU arbitrage— ukutshaja ibhetri xa amandla engabizi kakhulu (ubuninzi belanga ebusuku okanye emini) kunye nokukhupha xa amaxabiso enyuka; kwiimarike ezinamaxabiso aphantsi, indawo yokugcina ingahlawulwa ukuze itshajwe.
• Iinkonzo zegridi— ukulawulwa kwamaza, inkxaso yevolthi, kunye neekhontrakthi zokucheba ezifikelela kwincopho zihlawula ngqo abaqhubi beendawo zokugcina izinto; ii-interface ze-OCPP 2.0.1 kunye ne-IEC 61850 zivumela ukuthatha inxaxheba kwiimarike ezininzi.
• Inkxaso yongxamiseko— iindleko zokungasebenzi zithintelwe kwiinqanawa ezinengeniso exhomekeke ekufumanekeni kokutshaja.
