Abstract：Power distribution method is the key issue of PV-based battery switch stations(BSS). This paper first introduces the system structure of PV-based BSS and the functional model of basic units. In order to evaluate system operating performance, indicators such as battery swap service availability and renewable energy utilization ratio are established. On this basis, the dynamic power distribution method of PV-based BSS considering battery reservation is proposed. For one aspect, by introducing the prediction results of short-term battery swap demand, battery swap service model is established. For another, the power distribution model is given according to the available batteries and PV power in a certain period of time. By simulated calculation of a practical PV-based BSS, analysis about the power balance and operating performance indicators demonstrates the rationality and accuracy of these models. Simulation results indicate that on the premise of ensuring battery swap service availability, the proposed method will increase local utilization ratio of PV power effectively. This method will provide a theoretical basis and technical support for optimal operation of BSS in demonstration cities.
