Ukuqinisa Ukuzinza Kwegridi Ngenethiwekhi Esatshalaliswayo Ye-BESS

Impendulo Esheshayo:Amanethiwekhi e-BESS asatshalaliswa aqinisa ukuzinza kwegridi ngokufaka [amayunithi okugcina amabhethri] amaningi amancane (https://www.midapower.com/energy-storage-charging-station) esifundeni - ezindaweni zokugcina imikhumbi, izindawo zokushaja ezinkulu, izakhiwo zebhizinisi, kanye nezindawo zelanga - futhi azihlanganise ngesofthiwe yokuphatha amandla ibe yisitshalo samandla esibonakalayo (i-VPP) esinikeza ukulawulwa kwemvamisa, ukwesekwa kwe-voltage, ukushefa okuphezulu, kanye nezinsizakalo zokuqina kumqhubi wegridi. Ngoba impendulo yenzeka endaweni (ngaphansi komzuzwana owodwa wemvamisa, ngokushesha kwe-voltage), isitoreji esisatshalaliswayo sidlula izitshalo ezinkulu eziphakathi ngesivinini nokuthembeka, futhi asidingi imizila emisha yokudlulisela. Kubanikazi, iyunithi ngayinye esatshalaliswayo ithola imithombo eminingi yemali engenayo - izinkokhelo zamandla, i-arbitrage yamandla, ukonga kwezindleko zesidingo, kanye nemali engenayo yesevisi ehambisanayo - kuyilapho inethiwekhi iyonke iba yimpahla eguquguqukayo kakhulu yegridi. Izimakethe zaseYurophu naseNyakatho Melika sezivele zikhokha ama-30-120 USD/MW-h ukuze kuphendulwe ngokushesha kwemvamisa, okwenza amanethiwekhi e-BESS asatshalaliswa abe ngenye yezingxenye ezikhula ngokushesha kakhulu engqalasizinda yegridi.

Izinto Ezibalulekile Okufanele Uzicabangele:

• Amanethiwekhi e-BESS asatshalaliswa aguqula izinkulungwane zamayunithi amancane okugcina izinto abe yimpahla eyodwa yegridi eguquguqukayo, enikeza izinsizakalo izitshalo ezihlanganisiwe ezingenakukwazi ukuzifanisa ngesivinini noma indawo.
• Ukulawulwa kwemvamisa kuyisevisi enenani eliphakeme kakhulu: impendulo yesikhashana ithola u-30-120 USD/MW-h wezinkokhelo zamandla ezimakethe ezinkulu.
• Izendlalelo zokuhlanganisa (amapulatifomu e-EMS + VPP + OCPP 2.0.1 + ISO 15118) yizo eziguqula amabhethri ahlakazekile abe umthombo owodwa ongathunyelwa.
• Amayunithi afanayo asatshalaliswayo akhonza isayithi lawo elibamba kuqala — anciphisa izindleko zokufunwa ngo-20–40% — bese ethengisa ukuguquguquka kwegridi okwesibili.
• Ihadiwe yokugcina yephrothokholi ejwayelekile, ehambisanayo, iyingqimba evumelayo: amayunithi ajwayelekile kuphela angahlanganiswa ngendlela engabizi kakhulu ngezinga.

Kungani Ukuzinza Kwegridi Kuphenduka Inkinga Esabalele

Umqhubi wegridi wesifunda eningizimu ye-United States ubukele i-ramp yakusihlwa: ukukhishwa kwelanga kwehla, umthwalo womoya opholile uyakhuphuka, kanye nokuphakama komthwalo we-net wemizuzu engama-30 kuyakhula minyaka yonke njengoba izinto ezivuselelekayo zisusa izitshalo ezishisayo. Ithuluzi lomqhubi lesikhathi esidlule - iziqongo ezinkulu zegesi kanye nesitoreji esiphakathi - kuyabiza ukwakha, kuyashesha ukuphendula (imizuzu emi-2-10), futhi kutholakala kude neziphakeli zokusabalalisa eziminyene lapho kwenzeka khona izinkinga ze-voltage. Okwamanje, zonke izikhumulo zokushaja ze-EV, uphahla lwezentengiselwano, kanye ne-logistics depot esifundeni kuyimpahla yokugcina engase ibe khona engasebenzi.

Ukuzinza kwegridi sekuba yinkinga esabalele ngenxa yezizathu ezintathu zesakhiwo. Okokuqala, ukungena okuvuselelwayo kuqeda i-inertia ehambisanayo: ukuphambuka kwemvamisa kukhula kakhulu futhi kufika ngokushesha, impendulo edingayo ngemizuzwana kunokuba kube yimizuzu. Okwesibili, ukukhiqiza kuthuthela emaphethelweni okusabalalisa (ilanga elingaphezulu kophahla, isitoreji somphakathi), ngakho-ke izinkinga ze-voltage kanye nokuxinana zitholakala kuma-feeder izitshalo eziphakathi ezingakwazi ukuwabona, ingasaphathwa eyokulungisa. Okwesithathu, ukwanda kokudlulisela kuhamba kancane futhi kuyabiza - imizila emisha ithatha iminyaka engu-7-10 kanye nezigidigidi zokutshalwa kwezimali - kuyilapho amabhethri asakazwayo esetshenziswa ezinyangeni lapho kudingeka khona. Umphumela uba ukwakheka kwegridi lapho izinsizakalo zokuzinza zihlinzekwa khona ngokwandayo yimikhumbi yezindawo zokugcina ezincane, ezihlelekile kunezitshalo ezimbalwa ezinkulu.

Ukwakheka Kwezinsizakalo Zegridi: Lokho Okusatshalaliswa Yi-BESS Okukuthengisayo Ngempela

Amayunithi e-BESS asatshalaliswa athola imali engenayo ngokuthengisa izinsizakalo eziyisithupha ezihlukene, ngayinye inesikhathi sayo sokuphendula, ubude, kanye nesakhiwo semakethe:

Ukulawulwa kwemvamisa kuyisevisi ye-anchor ngoba yenza imali ngenzuzo ecacile yamabhethri asatshalalisiwe: isivinini. Iyunithi ye-lithium-ion ingakhuphuka isuka ku-zero iye emandleni aphelele ngaphansi kwama-millisecond ayi-100 futhi igcine leyo mpendulo unomphela - ikhono izitshalo ezishisayo ezingenakulifinyelela futhi izimakethe ezikhokhela ngalo ngamanani aphezulu. Ukusekelwa kwe-voltage kusebenzisa indawo: ibhethri elise-feeder egcwele lilawula i-voltage lapho idingeka khona, ligwema ukulahlekelwa kanye nokubambezeleka komjovo okude.

Okuhlanganisiwe vs. Okusatshalaliswa: Ukuqhathaniswa Kwezakhiwo

Lokhu kuqhathanisa kuchaza indlela imboni ehamba ngayo: ngenkathi izitshalo ezihlanganisiwe zisadingeka ukuze kugcinwe amandla amaningi, imali encane yokutshalwa kwezimali okuzinzile kwegridi iya ngokuya iya kumanethiwekhi asatshalaliswa, ngoba ayashesha ukwakhiwa, ashibhile nge-MW ngayinye, futhi aqinile ngokwemvelo.

Ukwakhiwa Kwezakhiwo: Indlela Inethiwekhi Ye-BESS Esatshalalisiwe Ehlelwa Ngayo

Inethiwekhi ye-BESS esatshalaliswe iyisistimu enezingqimba ezintathu.ungqimba lwehadiweiyinqwaba yamayunithi okugcina ajwayelekile — amabhlogo ebhethri, amamojula wamandla aqondene nezinhlangothi ezimbili, kanye namashaja — ngalinye line-BMS yendawo kanye nesivikelo.ungqimba lokulawulayi-EMS esezingeni lesayithi eqhuba ukulungiswa kokushaja kwesidingo sesayithi elibambayo, ibamba i-headroom yebhethri, futhi iveze isikhombimsebenzisi esijwayelekile semiyalo yegridi.isendlalelo sokuhlanganiswauhlelo lokuphathwa kwezinsizakusebenza zamandla olusatshalaliswa (i-DERMS) oluhlanganisa amakhulu noma izinkulungwane zamayunithi kuphothifoliyo eyodwa ethunyelwayo bese luyibhida ezimakethe.

Izindinganiso ezintathu zephrothokholi zenza izendlalelo zisebenzisane:

• I-OCPP 2.0.1ilawula ukulawula ishaja kanye nesitoreji kuyo yonke inethiwekhi, inezela ukuphepha kwe-TLS kanye nezinto zokuqala zokushaja ezihlakaniphile ezijwayelekile ezingenazo izinhlelo zokusebenza ezindala ze-1.6J.
• I-ISO 15118 (kufaka phakathi -20)yandisa izimoto kumabhethri ezimoto, ngakho-ke [ama-EV anekhono le-V2G](https://www.midapower.com/30kw-40kw-v2g-charging-module-bidirectional-ac-dc-converter-product/) ezindaweni zokugcina izimoto aba umthamo owengeziwe osabalalisiwe.
• I-OpenADR 2.0b / DNP3 / IEC 61850xhuma ungqimba lokuhlanganisa kuzinsizakusebenza kanye nama-TSO emicimbini ye-DR, amasignali omthetho, kanye ne-telemetry.

Isimiso sobunjiniyela siwukuthi iyunithi ngayinye kumele ibe nenzuzo ngayinye endaweni yayo — ngokonga imali edingekayo, i-arbitrage, kanye nemali engenayo yesevisi yokushaja — ngaphambi kokuba ithunyelwe kumasevisi egridi. Imali engenayo yegridi iyona engcono; ezomnotho zesayithi yizona zinto eziyisisekelo. Yilokhu okwenza amanethiwekhi asakazwe afaneleke ukubhanga: icala lebhizinisi leyunithi ngayinye alixhomekile emananini esevisi asekelayo aguquguqukayo.

Amaphethini Okusetshenziswa Kwangempela

Amaphethini amathathu okusetshenziswa alawula amanethiwekhi amanje e-BESS asatshalaliswa, ngalinye linamathela isitoreji esikhaleni sokusetshenziswa okungokoqobo.

Izindawo zokubeka imikhumbi kanye nezindawo zokushaja.Indawo yokugcina ugesi edepho inciphisa inani lokushaja, bese ithengisa umthamo wokulawula ngamahora angekho emsebenzini. I-MIDA's [482 kWh/320 kW](https://www.midapower.com/320kw-482kwh-bess-charger-mobile-ev-charging-station-energy-storage-system-product/) kanye ne-[625 kWh/400 kW iziteshi ezihlanganisiwe](https://www.midapower.com/400kw-625kwh-bess-charger-station-mobile-charging-battery-energy-storage-system-product/) isebenza kahle kakhulu le ndima: ama-battery buffers ayashaja ngenkathi inkontileka ye-VPP yenza imali ngefasitela elingasebenzi. Idepho ephethe amabhasi angu-30 ivame ukukhiqiza amandla angu-500 kW–1.5 MW kunethiwekhi ngaphandle kwendawo yokugcina enikezelwe.

Amaqoqo okushaja emigwaqweni emikhulu kanye namabhizinisi.Iziteshi eziningi ze-120-400 kW eceleni komhubhe zihlanganiswe zaba yiphothifoliyo yesifunda, zinikeza ukucheba okuphezulu endaweni ngayinye kanye nokulawulwa kwemvamisa ye-TSO. Ngenxa yokuthi ihadiwe ijwayelekile futhi ihambisana nephrothokholi, ukuhlanganiswa kuyisenzo sesofthiwe kunokuba kube ukuvuselelwa kwehadiwe.

Izinhlelo ezihlanganiswe yilanga kanye nezingaphandle kwegridi.Amayunithi okugcina amandla elanga asakazekile — njenge-MIDA’s [200 kWh/120 kW off-grid solar MPPT charger](https://www.midapower.com/200kwh-120kw-mobile-ev-charger-off-grid-solar-mppt-dc-fast-charging-station-product/) — umkhiqizo ovuselelekayo oqinile futhi unikeza amandla okufika eziqhingini. Ezifundeni ezinegridi ezibuthakathaka, lawa mayunithi anikeza insizakalo yokuqina engenakukwazi ukugcinwa yizimpahla ezimaphakathi: agcina imithwalo ebalulekile ku-inthanethi ngesikhathi sokungasebenzi.

Amamodeli Ebhizinisi kanye Nemithombo Yemali Engenayo

Abaqhubi benza imali ngamanethiwekhi asatshalaliswe ngemithombo emihlanu yemali engenayo ehlanganisiwe:

1. I-Demand-charge kanye ne-energy arbitrage endaweni yokusingatha— Ukwehliswa kwezindleko zesidingo esingu-20–40% kanye nokonga amandla kwe-TOU (isisekelo esikhokhela ibhethri). 2.Ukulawulwa kwemvamisa kanye nezinsizakalo ezihambisanayongezinkontileka ze-TSO noma ukubamba iqhaza kwabahlanganisi — 30–120 USD/MW-h yezinkokhelo zomthamo. 3.Ukubamba iqhaza emakethe yamandlalapho isitoreji sifaneleka khona — izinkokhelo zonyaka zokukhipha impahla ngesikhathi sezehlakalo zokuntuleka. 4.Izinkontileka ze-DR kanye nokuguquguqukangezinsiza — izinkokhelo zesenzakalo ngasinye zokunciphisa noma ukufaka okuhleliwe. 5.Izinsizakalo zezimoto ze-V2G— amabhethri ezimoto athunyelwa ngesikhathi samafasitela okulawula, ethola izinkokhelo zamandla nge-MWh ngayinye ngaphezu kwamandla esiteshi ngokwaso.

Ukufakwa kwe-stacking kuyasebenza ngoba izinsizakalo zihlukaniswa ngesikhathi: ibhethri alikwazi ukulawula imvamisa futhi linciphise i-peak ngesikhathi esifanayo, kodwa i-peak ingu-4-6 ntambama, isidingo somthetho siyaqhubeka, futhi amafasitela okushaja izimoto ebusuku ahlukene - i-EMS ihlela ikhono ngalinye libe yisikhathi salo.

Ukwenza Inethiwekhi Ibe Yiqiniso: Okufanele Kwenziwe Abasebenzi

Amanethiwekhi e-BESS asatshalaliswa afakazelwe ngezinga, kodwa imbuyiselo ingeyabasebenzi abenza izisekelo:

1. Yenza ihadiwe ibe yi-standard.Khetha umndeni owodwa womkhiqizo we-modular onokusekelwa kwe-OCPP 2.0.1 kanye ne-ISO 15118 kuwo wonke amasayithi — umnotho wokuhlanganisa uyawa uma isayithi ngalinye lisebenzisa amaphrothokholi ahlukene. 2.Beka yonke iyunithi kumnotho wesayithi lokusingatha kuqala— ukonga kwezindleko zokufunwa kanye nemali engenayo yokukhokhisa kumele kukhokhele icala lebhizinisi eliyisisekelo. 3.Yenza isivumelwano nomqambi kusenesikhathiukuze imikhumbi ikwazi ukubhida emakethe kusukela ngosuku lokuqala kunokuba ngemva kwenqubo yokufaneleka yonyaka. 4.Gcina i-headroom ngokwedizayini— usayizi wamabhethri ungaphezu kuka-20–30% wezidingo zesayithi ngakho-ke izinsizakalo zegridi azilokothi ziphazamise ulwazi lomshayeli. 5.Konke kwensimbi— amayunithi alinganisiwe, asebenzisa i-telemetry yiwo azothunyelwa ngabahlanganisi kanye nezinsizakusebenza; amandla angaxhunywanga ayimali efile.

Ukuzinza kwegridi kuya ngokuya kuba yinkinga esabalalisiwe, futhi impendulo iya ngokuya iba yisisekelo sempahla esabalalisiwe. Abasebenzi abasebenzisa isitoreji esijwayelekile, esisekelwe kwiphrothokholi ezindaweni zabo namuhla abagcini nje ngokuthuthukisa izindleko zabo zamandla - baba abahlinzeki bokuguquguquka kwegridi ka-2030, bethola imali evela kwingqalasizinda ephinde ikhonze ibhizinisi labo eliyinhloko. Umphumela wenethiwekhi ungokoqobo: yonke iyunithi eyengeziwe ebalwe ngokwejwayelekile yenza iphothifoliyo ehlanganisiwe ibe yigugu kakhulu, ikwazi ukuthunyelwa kalula, futhi iqine kakhulu - kumqhubi kanye negridi.
