Lub ntsiab lus tseem ceeb: tus nqi transformer uas zam tau ib leeg feem ntau sib npaug lossis ntau dua qhov peev txheej BESS ntxiv. Lub xaib xaus rau kev them tus nqi tag nrho zoo sib xws, tab sis BESS version muab cov nyiaj tau los ntxiv thiab kev txuag nqi txhua hli tom qab ntawd.
Cov Nqi Them: Cov Se Zais Cia rau ntawm Cov Chaw Them Nqi
Kev txuag nyiaj los ntawm kev thov thiab tus nqi them yog qhov tseem ceeb tshaj plaws rau kev lag luam ntawm qhov chaw them fais fab BESS. Lub tshuab no yog qhov txiav txim siab xwb tsis yog kev kwv yees xwb: EMS ntsuas qhov chaw thauj khoom hauv lub sijhawm tiag tiag thiab tso lub roj teeb tawm thaum twg lub sijhawm 15 feeb yuav teeb tsa qhov siab tshaj plaws tshiab.
Xav txog ib qho chaw uas muaj lub zog siab tshaj plaws 1,200 kW thiab tus nqi thov $ 15 / kW. Kev tso tawm 418 kWh BESS ntawm 240 kW thaum lub sijhawm siab tshaj plaws tuaj yeem txwv qhov chaw ntawm kwv yees li 960 kW. Kev txuag txhua hli yog kwv yees li 240 kW × $ 15 = $ 3,600, lossis $ 43,200 ib xyoos. Tshaj li kaum xyoo, qhov txiaj ntsig ntawd tshaj $ 430,000 - ntau dua li tag nrho cov nqi teeb tsa BESS hauv feem ntau ntawm cov lag luam.
Cov nyiaj txuag tau raws li tus nqi hluav taws xob. Cov chaw hauv California, New York, Lub Tebchaws Yelemees, lossis Australia, qhov twg cov nqi hluav taws xob xav tau nce mus txog $ 20– $ 40 / kW, pom cov nyiaj rov qab sai dua. Ib txoj cai npaj muaj txiaj ntsig: yog tias kev txuag hluav taws xob txhua xyoo ntau dua 12–15% ntawm tus nqi peev BESS, kev nqis peev tsim nyog tau kev tshuaj xyuas zoo.
Kev Sib Tham Txog Zog thiab Kev Sib Txuas Hnub Ci Ua Cov Nyiaj Tau Los
Ntxiv rau kev zam cov nqi, BESS tuaj yeem khwv tau nyiaj tau los qhov twg cov cai ntawm kev ua lag luam tso cai:
