Aiming at the problems of renewable energy output uncertainties and single scenario operation mode of energy storage systems, a cooperative game robust optimization control method for wind-solar-shared energy storage system based on dual-settlement mode of power market is proposed in this paper.
Considering the high investment cost of the energy storage system, it is proposed that the shared energy storage will participate in the operation mode of the multi-virtual power plant system as an independent subject, which will help to realize a win-win situation in cooperation between the VPP operator and the shared energy storage operator.
Shared energy storage is applied to integrated energy systems, providing power auxiliary services to renewable energy and power grids within a certain region through interconnection, coordinated control, and overall management of power devices at different levels.
We adopt a cooperative game approach to incorporate storage sharing into the design phase of energy systems. To ensure a fair distribution of cooperative benefits, we introduce a benefit allocation mechanism based on contributions to energy storage sharing.
The simulation results show that the cooperative game robust optimization model achieves the optimal operation of the wind-solar-shared energy storage system considering multiple uncertainties, which can improve the ability of the system to cope with the uncertainty risk and the reliability of the system. 1. Introduction
For example, multiple buildings within a community or business park can share a centralized storage facility, enabling them to collectively manage their energy needs more effectively. This application not only lowers individual energy costs but also enhances the community’s energy resilience.
