Kumeta molunjika pogwiritsa ntchito chojambulira cha BESS EV kumachepetsa ndalama zamagetsi poika malire a mphamvu yapamwamba kwambiri ya mphindi 15 yomwe imakoka katundu wochokera ku malo olowera kuchokera ku gridi, chifukwa mitengo yamalonda ndi mafakitale imalipira ndalama zofunidwa — nthawi zambiri $8–$25 pa kW pamwezi — kutengera kuchuluka kwa ndalamazo. Malo ochapira mwachangu okhala ndi ma charger a 480 kW amatha kulembetsa mosavuta kuchuluka kwa 400 kW pamwezi, zomwe zimawononga $3,200–$10,000 pamwezi kapena $38,000–$120,000 pachaka mu ndalama zofunidwa zokha. Dongosolo losungira mabatire lomwe limameta mpaka 200 kW limadula pakati pa chinthu chofunidwa ndipo, kuphatikiza ndi arbitrage ya nthawi yogwiritsira ntchito, limapereka ndalama zosungidwa za 30–60% pa bilu yamagetsi kwa ogwiritsa ntchito chochapira. Nthawi zobwezera za BESS zochapira molunjika m'malo ochapira amalonda nthawi zambiri zimakhala pakati pa zaka 3–6, pomwe batire limadzilipira lokha kudzera mu ndalama zochepa zofunidwa lisanapereke ntchito imodzi ya gridi.

Mfundo Zofunika Kwambiri

• Ndalama zofunidwa, osati kuchuluka kwa mphamvu, ndi gawo lalikulu kwambiri la ndalama zomwe zimawongoleredwa m'malo ochapira magetsi amagetsi, zomwe zimafika pa 30–70% ya ndalama zonse zamagetsi.
• Kumeta tsitsi kwa BESS peak kumakhudza kufunikira kwa mphindi 15, zomwe zimapangitsa kuti chilango chokhazikika pamwezi chikhale chotsika mtengo komanso chodziwikiratu.
• Zowongolera za EMS zolosera (zolosera za kufika, nthawi yochaja, SOC ya batri) zimachepetsa mphamvu ya batri yofunikira ndi 15–30% poyerekeza ndi malamulo osasinthika.
• Ndalama zosungidwa: kuchepetsa ndalama zomwe zimafunika + TOU arbitrage + kupewa kukweza transformer + ndalama zomwe zimapezedwa pa ntchito ya grid.
• Kubweza kwa malonda nthawi zambiri kumakhala kwa zaka 3-6; malo omwe ali m'madera omwe anthu ambiri amawafuna (California, Germany, Australia) amatha kubweza kwa zaka zosakwana zitatu.

Chifukwa Chake Bilu Zamagetsi Zakwera: Kufotokozera Ndalama Zofunikira

Woyang'anira malo onse wawona chinthu cha mzere: "chofunikira" kapena "chofunikira mphamvu," nthawi zambiri chimakhala chachikulu kuposa mphamvu yamagetsi yokha. Chilipo chifukwa chakuti magetsi ayenera kumanga ndikusunga mphamvu zokwanira zosinthira magetsi, zodyetsa, ndi zopangira kuti zigwire ntchito kwa mphindi 15 zoyipa kwambiri za kasitomala aliyense pamwezi - ndipo amawononga mphamvuyo mosiyana ndi mphamvu zomwe zimagwiritsidwa ntchito.

Kapangidwe kake ndi kosavuta. Meta imalemba kuchuluka kwa mphamvu yapakati pa kW yomwe imakokedwa mu mphindi 15 zilizonse pamwezi uliwonse wolipira. Katunduyu amachulukitsa mtengo wake ndi chiwongola dzanja - nthawi zambiri $8–$25 pa kW pamwezi ku North America ndi Europe, komanso kukwera kwambiri m'ma network odzaza - ndipo amawonjezera ku bilu. Chofunika kwambiri, kukwera kamodzi kwa mphindi 15 (mabasi atatu akuchaja nthawi imodzi, kuzizira pang'ono, kuthamanga kwakukulu) kumakhazikitsa maziko a kufunikira kwa mwezi wonse, mosasamala kanthu kuti katunduyo ndi wochepa bwanji nthawi yonse yotsala.

Kwa ogwiritsa ntchito magetsi a EV, mphamvu yamagetsi imakhala yofanana ndi yachibadwa. Ma charger othamanga amakhala ndi mphamvu zambiri - charger ya 240 kW yomwe imatulutsa mphamvu yonse imalembetsa 240 kW ya kufunikira pa bay iliyonse. Malo okhala ndi ma charger anayi ndi magawo atatu nthawi imodzi amatha kukhazikitsa chiwongola dzanja cha 500–700 kW pamwezi nthawi imodzi. Kuchuluka kwa mphamvu yamagetsi:

Ziwerengerozi zikufotokoza chifukwa chake kusungira sikulinso kosankha kwa omwe akuchaja kwambiri: ndalama zofunira ndi msonkho wokhazikika pa khalidwe la peak, ndipo njira ziwiri zokha zochepetsera ndikuchepetsa peak (kusungira) kapena kusintha magawo (kukonzekera).

Njira Yogwiritsira Ntchito Kumeta Molunjika Pogwiritsa Ntchito BESS

BESS imadula mphamvu zake mwa kusiyanitsa pakati pa kufunikira kwa malo nthawi yomweyo ndi cholinga chofunidwa chomwe chakhazikitsidwa. Pamene mphamvu ya charger ikukwera kupita ku chivundikiro, batire imatuluka kuti iphimbe zochulukirapo; pamene katundu ali wochepa, batire imatuluka kuchokera ku gridi pamlingo wokhazikika komanso wotsika. Chifukwa chake, kulowetsedwa kwa gridi ya malo sikupitirira chivundikirocho, ndipo chiwongola dzanja cha mwezi uliwonse chimakhala pansi pa cholingacho kapena pansi pake.

Tsatanetsatane wa kukhazikitsa ndi wofunika kwambiri kuposa momwe mabatire amagwirira ntchito pano. Dongosolo loyang'anira mphamvu (EMS) liyenera kugwira ntchito pa sub-second control loop, chifukwa nthawi yochaja imatha kuchoka pa 50 kW kufika pa 250 kW m'masekondi pamene galimoto ikuyamba nthawi kapena pamene batire ikuyamba kugwira ntchito. Ntchito zazikulu zowongolera:

1. Kuyeza katundu wolowera nthawi yeniyenipa resolution ya sekondi imodzi, zomwe zikuwonetsa nthawi yolumikizirana ya kampaniyi ya mphindi 15. 2.Kukwaniritsa zofunikira pa kufunikira kwa ndalama— chowongolera chimasunga gridi yolowera pansi pa chivundikiro, ndikutulutsa malo osungira ngati pakufunika. 3.Kasamalidwe ka malo osungira a SOC— batire siliyenera kudzitulutsa lokha nthawi yolipira isanatseke; EMS imateteza malo osungira nthawi zomwe zimakhala zoopsa kwambiri (madzulo, m'mawa ozizira).Kutaya kwa katundu woyikira ngati njira yomaliza— ngati batire ya SOC igunda pansi, chowongolera chimachepetsa ma charger osafunikira kwenikweni m'malo mophwanya chivundikirocho.

Kulamulira Kosasunthika ndi Kolosera

Makina oyambilira ometa tsitsi lalitali ankagwiritsa ntchito mphamvu zokhazikika: kutulutsa mphamvu zoposa 250 kW, kubwezeretsanso mphamvu zosakwana 150 kW. Kuwongolera kolosera kumawongolera izi mwa kuneneratu:
