Integrating the charging scheduling model and constraints into the scheduling optimization process and conducting a comprehensive economic evaluation of the charging station, could achieve the optimal scheduling strategy of charging piles .
Previous studies always assume the charging demand of EVs as a constant power profile , or employ simplistic rules to assign the power of charging piles, such as assuming that EVs would be charged at maximum power upon arrival at the charging piles .
The storage energy St of BESS at time t is equal to the sum of the storage energy St-1 at the previous time t -1 and the net charging power during the time period Δ t, as shown in Eq. (21). (21) S t = {(P t P t) Δ, = 1 1 + (P t P t) Δ, ≥ 2
