Considering the Demand Side Response of Electric Vehicle to Grid

Abstract

When electric vehicles switch on power grid largely, it will impact on the operation of power system if there aren’t any management and control. This paper compared different characteristics of electric vehicles in charge and discharge from different regions. It divided the situations into three areas: residential area, commercial district, industrial zone; And established avoidable load model, transferable load model and combined load model based on different types of users. Through the analysis of the examples, verified that different load model can effect on loads from different regions, and finally concluded that, the models can play the role of “cut a peak to fill valley”. Therefore, it is very important to transfer part of the electro-demand from the peak period to low period through reasonable price guide.
