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 .
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 .
The stochastic and intermittent characteristics of solar irradiance could significantly affect the scheduling strategies and design capacities of the PV/BESS integrated EV charging station. Besides, the difference of regional solar irradiance conditions is also the main factor affecting the generalizability of the design.
Utilizing the proposed stochastic simulation method of EV behaviors, the integrated charging station would accommodate approximately 29604 EVs each year, and the total annual electricity demand is about 755.20 MWh.

Solar energy, harnessed from the sun, offers an abundant and clean power source, presenting an optimal solution for sustainable EV charging . However, solar intermittencies and photovoltaic (PV) losses are a significant challenge in embracing this technology for DC chargers.
