英文摘要：

The PV-based battery swapping station（BSS） is one of the typical forms of the integration of electric vehicle（EV） charging infrastructure and renewable energy utilization.This paper proposed a capacity optimization method of the PV-based BSS considering second-use of EV batteries.Based on a certain system architecture and energy exchange strategy,the objective function of the capacity optimization model was established with the objective of the maximum annual profit of the PV-based BSS according to the energy exchange demand of EVs.In order to determine second-use capacity of EV batteries in every year,the calculation model was established by Monte Carlo simulation method on the basis of EV battery capacity degradation model and statistical model of EV daily driving distance.Differential evolution（DE） algorithm was adopted to solve the optimization model and the calculation procedure of system annual profit was analyzed in detail.Finally,the planning of the PV-based BSS in a certain area was taken as an example.The analysis verifies the reasonableness of the capacity optimization model presented in this paper.
