利用储能系统提升电网电能质量研究综述

Summary of Research on Improving Energy Quality of Power Grid By Using Energy Storage System

储能系统可分为能量型、功率型两种类型装置,用于平抑不同类型的功率波动,典型应用场景有电源侧、电网侧、用户侧。储能系统在电网中的应用可有效解决多种电能质量问题,比如电压偏差、谐波、三相不平衡等稳态电能质量问题,以及电压波动/闪变、电压暂降、综合电能质量等动态电能质量问题。

The energy storage system can be divided into energy type and power type devices,which can be used to suppress different types of power fluctuations.Typical application scenarios include power supply side,power grid side and user side.The application of energy storage system in the power grid can effectively solve a variety of power quality problems,such as voltage deviation,harmonics,three-phase unbalance and other steady-state power quality problems,as well as voltage fluctuations/flicker,voltage sag,integrated electrical energy Quality and other power quality problems.
