说明：  在simulink下构建模型仿真电动汽车辅助调频的功能，在知网上有对应的额论文可以参考，这是simulink模块实现的功能
(Build a model to simulate the function of assisted frequency modulation of electric vehicles under simulink. There is a corresponding amount of papers available on Zhizhi.com, which is a function implemented by the simulink module.)
