Analysis of the Application and Control of the Distributed Energy Storage System in Microgrid

Abstract

Because of the intermittence and randomness of renewable energy and the continuous variability of load. By configuring a certain capacity of energy storage in microgrid, the active and reactive power throughput can be flexibly and quickly adjusted to smooth load fluctuations and reliability of power supply improvement. It can improve the power quality and keep the system stable. Therefore, the application potential of distributed energy storage system in microgrid and distribution system is huge. In terms of give full play to the performance advantages of energy storage through distribution system, it is necessary to study the core technologies of modular integration, topology, capacity design and control of energy storage through distribution system. The feasibility and value of energy storage through distribution system in power system engineering are demonstrated. Based on the analysis of relevant requirements, a energy storage through distribution system based on micro energy storage unit is proposed in this paper. This structure is very suitable for energy storage components to be connected to the micro-grid to achieve plug and play, high efficiency, high reliability and high flexibility of energy storage system applications.
