Energy Balance Considered Dynamic Coordination Strategy on Energy Storage System Incorporated Hybrid Energy System

Abstract

With development of renewable energy industry, the distributed energy resources, such as wind power (WP) generation in some areas has gradually increased. Due to the fluctuation of WP-alone power generation, the introductive of energy storage system (ESS) is an effective way to reduce waste power. In this paper, optimized coordination strategy of WP-ESS, featured with battery swapping station (BSS), is proposed, which aims to use batteries to realize the dynamic energy balance in the regional hybrid energy system. This paper describes and simulates the specific operation model, and compares the system without BSS under different output and load levels. The results show that the proposed system operation strategy is a feasible method to effectively increase the local utilization of WP.
