Microgrid Optimal Dispatch Model Considering Energy Storage System

In order to alleviate the impact of grid-connected new energy micro-grid including wind power and photovoltaic on the safe operation of the system, a micro-network optimization scheduling strategy considering energy storage system under time-sharing electricity price is proposed. The investment cost, pollution penalty cost and main network purchase cost are considered respectively, and the micro-network main network joint operation optimization model is established. The simulation results are used to analyze the optimization results under different scenarios. The results of the example show that the proposed strategy and model can effectively realize the micro-network optimization scheduling, effectively reduce the annual operating cost of the micro-grid including electric vehicles and storage batteries, and ensure the joint safe operation of the micro-network and the main network.
