Energy Exchange Model of PV-Based Battery Switch Stations Based on Battery Swap Service and Power Distribution

The integration of renewable energy sources(RES) and electric vehicles´ charging and swapping facilities can effectively improve the efficiency of clean energy utilization and carbon emission reduction. How to establish a reasonable energy exchange model of a PV-based battery switch station(BSS) is still an important research field which is being studied. This paper focuses on the model building about energy exchange in PV-based BSS. According to the battery swapping demand of EVs, the basic principles of energy exchange strategy is proposed, then the battery swap service model and power distribution model are established. Analysis about the system balance of power and energy validates the rationality of the optimization model. The proposed model can provide foundation for the planning and design of the PV-based BSSs.
