Wanpela ripot bilong Nesenel Riniubel Eneji Leboretori (NREL) i tok, wantaim ol kost bilong bateri yunit kapasiti i stap wankain, bikpela kapasiti bilong eneji stoa sistem, ol narapela kos i go daun long wanwan yunit bilong kapasiti. Dispela i mekim ol Battery Energy Storage Systems (BESS) i kamap gutpela moa long ol bikpela-kapasiti eneji storage aplikesen, olsem yumi lukim long tebol aninit.
Kost brukdaun bilong wanpela litiam-ion bateri eneji stoa sistem
Moa yet, kos bilong wokim, putim, na kirapim ol kontena BESS (Battery Energy Storage Systems) i stap long tebol aninit.
BESS Kost Proporsen Distribusen (Tebol 2-4)
| BESS Paramita | Kontena/ Banis | Elektrikel | Straksa | Tempereja Kontrol | Proteksen long paia | PCS (Inverter) | Ol Bateri Sel |
|---|---|---|---|---|---|---|---|
| 50kW/2h | 4.3% | 11.3% | 8.7% | 3.4% | - | 7.5% | 64.8% |
| 250kW/2h | 1.5% | 5.2% | 5.6% | 2.4% | 2.3% | 7.0% | 76.0% |
| 2500kW/2h | 0.7% | 2.5% | 2.0% | 1.3% | 1.0% | 5.0% | 87.5% |
Sapos yumi kisim wanpela 250kW/2h kontena BESS olsem eksampel, ol bateri bai kisim samting olsem 76% bilong olgeta kos; kontena, lokal kontrola, tempereja kontrol, paia proteksen, pawa distribusen, na ol narapela samting (lait, kebol, na ol narapela) bai kisim samting olsem 15.5%; na PCS bai kisim samting olsem 7%. Tasol, grid-transfoma i no stap insait long sistem antap.
Yumi ken lukim olsem, long lukluk bilong ol hatwea na kos bilong wokim ol samting, taim kapasiti na pawa bilong ol eneji stoa sistem i wok long go antap, mak bilong kos bilong pawa konvesen sistem (PCS) na ol narapela lektrikel na straksel komponen bai go daun, na mak bilong bateri kos bai go antap oltaim. Olsem na, sapos ol i bosim pe bilong ol bateri, dispela bai i gat bikpela wok long daunim olgeta pe bilong ol bateri eneji stoa sistem (BESS).
