Optimal scheduling of isolated microgrid with battery switching station for electric vehicles

Since entering the 21st century, China has been developing rapidly, and electric vehicles have gradually entered the public eye as an alternative to gasoline vehicles. At present, the issue of battery swapping in electric vehicles is becoming the main factor restricting their development, and the rational development and research of new energy has become the top priority. Microgrid has become a reasonable product that meets the requirements. However, microgrid systems are not perfect. Today's battery swapping stations have integrated charging and discharging storage functions, which interact with microgrids to form energy exchange. However, microgrid systems today face issues such as tight energy supply and demand relationships and unstable loads. How to coordinate the good interaction between the two operating entities of microgrid and electric vehicle swapping station, ensure their respective interests, and ultimately achieve the goal of energy conservation and emission reduction, which is beneficial to society development has strong practical significance. This article conducts research on the economic dispatch strategies of electric vehicle battery swapping stations and isolated microgrids. Establish an economic dispatch model based on the dual layer optimization theory, treating the converter station and isolated microgrid as two independent entities; integrating the two into a system based on multi-objective optimization theory to study the economic benefits of isolated microgrids.
