Integrated Energy Optimal Scheduling with Multiple Energy Storage Systems

In recent years, the proportion of clean energy and new energy installed in the power supply side is increasing, and the ensuing problems of high wind and light abandonment rate and high power supply reliability are becoming more and more prominent. On the basis of the original integrated energy system, this paper considers the multi-energy storage system and the cooperative scheduling of client and energy supply side. In this paper, a multi-time scale economic scheduling model of multistorage integrated energy system considering demand response is established, and scheduling analysis is carried out on two time scales--day-ahead and intra-day. The simulation results show that the participation of demand response resources in multitime scale energy scheduling can make up for the shortage of storage capacity and reduce the operation and maintenance cost of equipment. In the dispatching stage of the day-ahead and intra-day, the demand response can further tap the dispatching capacity of the system and improve economic efficiency, reduce the situation of wind curtailment and load loss, and realize the full utilization of resources at the energy supply side and the user side.
