Abstract

In the process of combining renewable energy with energy storage,a multi-microgrid low-carbon economic optimization model considering shared energy storage is established to address the interactive relationship between multiple entities and the low utilization of energy storage. Energy storage station is built within the multi-microgrid area,and the shared energy storage dispatch center sets an energy storage discount service price based on net load fluctuation of each microgrid,and promotes charging and discharging transactions among microgrids through real-time charging and discharging prices. In the microgrid,users adjust their electricity demand according to the incentive demand response mechanism,and the microgrid model is established considering the carbon emission costs. The particle swarm optimization algorithm and solver are used to solve the shared energy storage-microgrid two-layer optimization model,and four operation scenarios are set for comparison. The simulation results show that the proposed model can effectively improve the operational benefits of each entity and reduce the carbon emissions of the system.
