计及共享储能分布式多能源系统的多目标优化

The energy network including shared energy storage is equal, open, economical, and efficient, which is the development direction of new energy system with new energy as entity. However, the coupling and contradiction between the benefits of shared energy storage and the cost ol energy users limit the planning and scheduling ol the system. On this basis, this paper proposes a multi-objective planning and optimization method for the distributed multi-energy system containing shared energy storage (MDES-SES). The synchronous optimization of unit capacity and output for MDES-SES is investigated as well. The optimal configuration of the system with two objective constraints is obtained by using the main objective function method and TOPSIS method. The operation of 1 -4 system (1 shared energy storage serves - 4 distributed energy systems) is further analyzed through the proposed optimization method. The results show that with the increase of shared energy storage capacity, the non-inferior solution becomes better, which comes from the compromise between the revenue of shared energy storage and the operating cost of distributed multi-energy system. Despite that, the improvement of the non-inferior solution narrows down with the increase of shared energy storage capacity.
