Microgrid scheduling method and system based on electric vehicle energy storage

The invention provides a microgrid scheduling method and system based on electric vehicle energy storage, and the method comprises the steps: gathering the available charging and discharging capacities of electric vehicles into a capacity-changing storage battery model, just considering the charging and discharging powers of the electric vehicles and the specific external performances at the microgrid level, and carrying out no scheduling on each electric vehicle; aiming at the particularity of isolated island operation of the microgrid, fully considering the uncertainty of renewable energy output and power load prediction, taking the minimum microgrid operation cost as an optimization target, and proposing an optimal microgrid scheduling strategy; therefore, the method has important significance for coordinated optimization operation of the electric vehicle and renewable energy after the electric vehicle is connected into the microgrid. 本发明提供了一种基于电动汽车储能的微电网调度方法及系统，将电动汽车可用充放电容量集聚为容量变化的蓄电池模型，在微电网层面只需考虑电动汽车及具体对
