The application of vehicle-to-grid (V2G) technology to control the charging and dischargingprocesses of electric vehicles can effectively alleviate the problems above by peak shaving and valley fillingmanagement and smoothing out renewable energy. In the past decade, this technology has become a hotresearch topic in the field of electric vehicles and power systems. Firstly, the paper introduc...
