Research on Economic Operation of Distribution Network Considering Energy Storage and Electric Vehicle Charging Station

The penetration of electric vehicles and energy storage devices in the power system is increasing, and they can participate in the optimal dispatch of the distribution network as adjustable resources. Firstly, based on the tidal model, energy storage operation model and electric vehicle cluster charging station model, a distribution network economic dispatching model is established, with minimization of network loss and minimization of charging cost of energy storage and charging stations as the day-ahead dispatching objectives. Secondly, a distributed solution scheme based on alternating direction multiplication algorithm with master-slave structure is designed for this optimization model to give full play to the autonomous coordination of resources within the distribution network. Finally, the simulation shows that the participation of energy storage and charging stations in the distribution network dispatch is beneficial to the energy storage operator and the distribution network in both directions, and the distributed solution scheme based on alternating direction multiplication algorithm is effective.
