Vim Li Cas Cov Nqi Hluav Taws Xob Thiaj Nce Siab: Kev Piav Qhia Txog Cov Nqi Xav Tau

Txhua tus thawj tswj hwm chaw ua haujlwm tau pom cov kab lus: "kev them nqi thov" lossis "kev them nqi muaj peev xwm," feem ntau loj dua li tus nqi hluav taws xob nws tus kheej. Nws muaj vim tias cov chaw muab hluav taws xob yuav tsum tsim thiab tswj kom txaus transformer, feeder, thiab lub peev xwm tsim hluav taws xob los pab txhua tus neeg siv khoom 15 feeb phem tshaj plaws ntawm lub hlis - thiab lawv muab tus nqi ntawd cais los ntawm lub zog siv.

Cov txheej txheem yooj yim heev. Lub 'meter' sau cov kW nruab nrab siab tshaj plaws hauv txhua 15 feeb thaum lub hlis them nqi. Lub tuam txhab hluav taws xob muab qhov siab tshaj plaws ntawd los ntawm tus nqi them - feem ntau yog $ 8– $ 25 ib kW ib hlis hauv North America thiab Europe, thiab siab dua hauv cov tes hauj lwm uas muaj neeg coob coob - thiab ntxiv rau daim nqi. Qhov tseem ceeb, ib qho kev nce siab 15 feeb (peb lub tsheb npav them tib lub sijhawm, lub sijhawm txias, kev sib sau ua ke) teeb tsa qhov kev thov rau tag nrho lub hlis, tsis hais qhov thauj khoom tsawg npaum li cas ntawm lub sijhawm seem.

Rau cov neeg tsav tsheb them hluav taws xob EV, qhov kev cuam tshuam yog qhov sib txawv. Cov chaw them hluav taws xob ceev yog lub zog siab - lub chaw them hluav taws xob 240 kW ntawm qhov tso zis tag nrho sau 240 kW ntawm kev thov ib lub thawv. Ib qho chaw uas muaj plaub lub chaw them hluav taws xob thiab peb lub sijhawm ua ke tuaj yeem teeb tsa qhov siab tshaj plaws txhua hli ntawm 500–700 kW hauv ib lub sijhawm. Kev cuam tshuam tus nqi sawv cev:

Cov lej no piav qhia vim li cas qhov chaw cia khoom tsis yog qhov xaiv tau rau cov neeg ua haujlwm them nqi loj: tus nqi thov yog tus nqi ruaj khov rau tus cwj pwm siab tshaj plaws, thiab tsuas yog ob txoj hauv kev los txo nws yog kom ua kom lub sijhawm siab tshaj plaws (kev cia khoom) lossis hloov sijhawm (kev teem sijhawm).

Cov Txheej Txheem ntawm Peak Shaving nrog BESS

Ib qho BESS txo cov siab tshaj plaws los ntawm kev nqus qhov sib txawv ntawm qhov xav tau tam sim ntawd thiab lub hom phiaj xav tau teem tseg. Thaum lub charger load nce mus rau qhov cap, lub roj teeb tso tawm kom npog qhov ntau dhau; thaum load tsawg, lub roj teeb rov them dua los ntawm lub grid ntawm tus nqi tiaj tus, qis. Yog li ntawd, qhov chaw ntawm lub grid import yeej tsis tshaj qhov cap, thiab qhov metered txhua hli peak nyob ntawm lossis qis dua lub hom phiaj.

Cov ntsiab lus ntawm kev siv tseem ceeb dua li cov tshuaj lom neeg ntawm lub roj teeb ntawm no. Lub kaw lus tswj hwm lub zog (EMS) yuav tsum ua haujlwm ntawm lub voj voog tswj hwm hauv qab vib nas this, vim tias kev them lub zog tuaj yeem dhia ntawm 50 kW mus rau 250 kW hauv vib nas this thaum lub tsheb pib lub sijhawm lossis lub voj voog ua ntej lub roj teeb koom nrog. Cov haujlwm tswj tseem ceeb:
