FAQS about Energy storage charging pile internal resistance 9 57

How ESS & PEB charging piles are connected?

ESS, PEB charging piles and the appliances of nearby residential or commercial areas (other loads) are connected to the secondary side of the distribution transformer. If the station has exclusive distribution transformer, the ratio of the power of other loads will be approximately zero.

Why is the controlled peak load constant under uncoordinated PEB charging scenario?

While under the uncoordinated PEB charging scenario, the controlled peak load remains constant with the change of the ESS price because all the capacity of ESS are used to shave the peak PEB charging loads during the high and peak TOU price periods, which brings larger benefits than ESS costs.
