Day-Ahead Scheduling With Renewable Generation Considering Shared Energy Storage

Abstract

The use of renewable energy is causing changes in the energy field, among which wind and water energy power generation technologies have developed rapidly. In the new power system with new energy as the main character, energy storage will be needed to assume the role of peak shaving and valley filling, voltage regulation and frequency regulation in the power system. At present, most energy storage power stations operate in an exclusive manner, resulting in low energy storage utilization. Based on the concept of resource sharing, considering the economics and feasibility of shared energy storage system with new energy characteristics, first analyze the complementary and controllable capabilities of energy storage that promote new energy consumption, and then study the multiple energy storage sharing mechanism that promotes new energy consumption Finally, a coordinated regulation strategy for shared energy storage system that takes into account reducing wind curtailment and smoothing output is proposed to provide customers.
