Ungayisombulula njani iGrid Capacity Pressure yeZitishi zokutshaja ngokukhawuleza?

Impendulo ekhawulezileyo

Ukusombulula uxinzelelo lomthamo wegridi kwizitishi zokutshaja ngokukhawuleza kufuna indlela enamanqanaba amaninzi:Iinkqubo zokugcina amandla ebhetri (i-BESS)isebenza njengesixhobo sokunciphisa imithwalo ephezulu,Ukulinganisela Umthwalo Oguquguqukayoilungiselela ukusasazwa kwamandla kwii-dispenser ezininzi, kwayeIi-Algorithms zokutshaja ezikrelekreleimfuno yokutshintsha ngokusekelwe kwiimpawu zegridi. Ngokudibanisa indawo yokugcina, abaqhubi banokusebenzisa iitshaja ezikhawulezayo kakhulu (360kW+) nakwiigridi ezilinganiselwe kwi-100kW, nto leyo enciphisa kakhulu iindleko zokuphucula iziseko zophuhliso kunye neentlawulo zegridi.

Izinto ezibalulekileyo ekufuneka ziqwalaselwe

• I-BESS Buffering: Iinkqubo zokugcina zikhupha amanzi ngexesha leeseshoni ezixakekileyo, zivumela ukutshaja ngamandla aphezulu ngaphandle kokudlula imida yegridi.
• Ukucheba okuPhezulu: Inciphisa iindleko zemfuno ngokuvala amandla aphezulu athathwe kwisixhobo.
• Ukwabelana ngoMthwalo oDynamic: I-logic yokwabiwa okukrelekrele kwe-MIDA isasaza amandla phakathi kwezibhamu ngokusekelwe kwizicelo ze-BMS zezithuthi zexesha langempela.
• Ukusebenza kakuhle: Iinkqubo zokuguqula amandla ezisekelwe kwiSiC (iiNkqubo zoGuqulo lwaMandla) zifezekisa ukusebenza kakuhle okungu-≥97.1%, nto leyo enciphisa inkunkuma yamandla.
• Ukuthobela imithetho: Ihambelana ngokupheleleyo ne-ISO 15118-20 kwi-V2G kunye nokusebenzisana kwegridi ekrelekrele.
• Ubungqina Bekamva: Ixhasa amaqonga e-1000V aphezulu e-voltage kunye nokupholisa ulwelo ukuze kutshajwe i-500A+.
• IngenisoIinkqubo ezidibeneyo zivumela ukubandakanyeka kwempendulo yemfuno, ziguqula ulawulo lwamandla lube liziko lenzuzo.

Ukuntywila nzulu: Ukusombulula iBottleneck yeGrid

1. Umngeni: Imfuno Ephezulu Xa Ithelekiswa Neziseko Zophuhliso Lwegridi

Njengoko ukwamkelwa kwe-EV kusanda, imfuno yeetshaja ezikhawulezayo ezingama-360kW kunye nama-480kW iyanda. Nangona kunjalo, iindawo ezininzi zasezidolophini nakwiindlela ezinkulu zijongene nemida yegridi, apho iitransformers zasekuhlaleni zingenakuxhasa iiseshoni zamandla aphezulu ngaxeshanye. Ukuhlaziywa kwegridi yesiqhelo kucotha, kubiza kakhulu, kwaye kudla ngokubandakanya ukuvunywa okuntsonkothileyo kwemithetho.

2. I-BESS njenge "Power Reservoir"

UkudibanisaIinkqubo zokugcina amandla ebhetri (i-BESS)ivumela abaqhubi bezikhululo ukuba "bagcine" amandla ngexesha leemfuno eziphantsi baze "bawakhulule" xa imoto iqhagamshela.

• Umzekelo: Indawo enoqhagamshelo lwegridi ye-100kW inokuxhasa iseshoni yokutshaja ye-360kW ngokutsala i-100kW kwigridi kunye ne-260kW kwi-BESS.
• Inzuzo ye-TCOOku kususa isidingo sokuphucula iitransformer ezinkulu, ezinokubiza ngaphezulu kwe-$100,000 kwindawo nganye.

3. Ukulinganisela Umthwalo Oguquguqukayo kunye nokutshaja okuKhawulezayo

Ii-MIDA'sIzikhululo zokutshaja ezikhawulezayo ze-DC ezingama-480kWsebenzisa iimodyuli zamandla ezikrelekrele ezinokwabiwa ngendlela eguquguqukayo. Ukuba iimoto ezimbini ziyatshaja, inkqubo ibeka phambili leyo ineState of Charge (SoC) esezantsi okanye isasaze amandla ngokulinganayo, ukuqinisekisa ukuba itotali iyonke ayidluli umda wesiza.

4. Ukuhlanganiswa kweLanga kunye neeMicro-grids

Ukudibanisaiinkqubo zokutshaja ze-EV zokugcina amandla elanga kunye nokugcinaidala imeko-bume yegridi encinci. Amandla elanga anika amandla ngokuthe ngqo iitshaja okanye atshaje iBESS, nto leyo enciphisa ngakumbi ukuxhomekeka kwigridi kwaye yehlisa amandla ekhabhoni.
