Research on Charging Method of Electric Vehicle Considering both Supply and Demand

In the context of the rapid development of electric vehicles, the study of orderly control methods for electric vehicles can effectively reduce the adverse impact of excessive grid connection frequency of electric vehicles, while also ensuring the economy and safety of the power system. As a result, this article investigates a daily billing approach that considers both consumers and the power grid. Initially, the client and grid expenses are calculated; The user's end-to-end needs grow in the first step. In the secondary planning, the peak shaving and valley filling of the electricity grid are extensively examined and obtain an EV charging and discharging strategy that considers both supply and demand. Based on this, a comparative analysis of different optimization schemes is conducted, and it is concluded that this scheme can achieve good results in reducing user costs, reducing power consumption, reducing load peaks, and reducing load volatility, so as to achieve a win-win situation for both the power system and users.
