School of Electrical Engineering, Beijing Jiaotong University, Haidian District, Beijing 100044, China; 2. Electric Power Research Institute of Guangdong Power Grid Corporation, Guangzhou 510080, Guangdong Province, China) ABSTRACT: To execute large-scale charging load forecasting and evaluate the influence of charging load on power grid, the 2 load modeling of electric vehicle (EV) charging station is an element task for them. The load of charging station is related to following factors: the flow of EV driven into charging station, the duration of charging and charging capability of the station, 2 so it presents a complex characteristics and it makes difficulties in the load modeling of charging station. Firstly, by means of analyzing the influence of the flow of EV driven into charging station on charging load, two modeling methods based on the description of load in charging station are proposed: one of them is based on mathematical formula, by which the charging 0  load can be rapidly calculated under certain preconditions, and the another is a method based on the simulation of dynamic proc
