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 .
If is within the power supply capacity of the interconnection line, the external power grid should consider charging the energy storage system while supplying electricity; When is less than zero or greater than zero and less than , this situation mainly relies on the energy storage system to maintain the balance of .
Although a large number of demonstration projects of the integrated charging station have been constructed and their technical feasibility has been validated, the capacity configuration of both PV and BESS are usually determined by empirical methods .
A novel design optimization for PV/BESS integrated EV charging station is proposed. A low-complexity mixed integer linear programming model is built by Big-M method. Integrating the PV hybrid model could achieve a superior capacity configuration. Optimal charging scheduling method is integrated to reduce PV/BESS design capacity.
