Optimal operation model of multi-energy microgrid considering a large number of EVs

Aiming at the problem of insufficient development of electric vehicle charging facilities due to the rapid development of clean energy vehicle technology, an electric vehicle charging station with multiple energy conversion including electricity and heat, a multi-energy micro-grid model and its optimal scheduling strategy are proposed. Based on the above background, first study the input and output characteristic models of electric and thermal energy. Then, with the multi-energy micro-grid operating cost as the minimum goal, a model of multi-energy micro-grid coordination and optimization of electric vehicle charging stations is established, and the variable particle swarm algorithm is used to solve the problem. Finally, based on the data of the operation of a multi-energy micro-grid in a city in my country, a simulation model of the multi-micro-grid optimization operation of electric vehicle charging stations is established. The simulation results show that this paper proposes a multi-energy micro-grid that considers the charging and discharging of a large number of electric vehicles in different scenarios. Optimized operation model, the charging station has a certain peak-shaving capacity on the grid under the premise of charging the EV.
