Operation optimization of battery swapping stations with photovoltaics and battery energy storage stations supplied by transformer spare capacity

Driven by the demand for carbon emission reduction and environmental protection, battery swapping stations (BSS) with energy storage (BESS) distributed generation (DG) have become one of key technologies to achieve goal peaking neutrality. Therefore, this paper proposes a strategy optimize operation BSS photovoltaics (PV) BESS supplied transformer spare capacity. Firstly, it introduces mechanism uses capacity building special transformers roof PV supply power avoid investment transformers. Secondly, establishes load model charging rules swapping. Thirdly, segmented pricing rental price is formulated guide operators preferentially rent during low rate periods. Aiming at maximum daily profit BSS, an optimization established number batteries be charged status in each period; on basis, response further proposed. Simulation results show that proposed can improve through shifting load. And configuration peak-shaving ability. Moreover, exponential greatly reduce high periods burden supply.
