摘要

为提高储能系统的利用率

改善微电网与电网并联运行下的电能质量

本文首先在分析非线性、敏感性负荷模型特征对并网点电压谐波分量扰动的基础上

提出了一种基于多功能储能变流器(power conversion system

PCS)的微电网电能质量综合补偿策略

在不改变储能变流器运行状态的前提下

结合多目标补偿电流的生成原理

利用PCS闲置容量快速并精确地选择性补偿谐波、无功及不平衡电流

以实现对并网电流补偿分量在畸变电压干扰下的输出电流控制

最后

搭建含储能装置的微电网系统

并对所提出的控制策略进行相关实验

结果表明其具有较好的电能质量治理能力。

Abstract

For enhancing the utilization of energy storage system and improving the power quality of micro grid and power grid in parallel operation condition

in this paer

a kind of comprehensive compensation strategy on power quality of microgrid on the basis of multi-function energy storage converter（power coversion system

PCS）is proposed. On the premise of not changing status of energy storage converter

the harmonic current

reactive power and imbalance current are compensated selectively by the use of spare capacity of PCS with combination of generation principle of compensation current and by the use of spare capacity of PCS

so to achieve the output current control of the grid connected current compensation component under the interference of distortion voltage. Finally

the microgrid system containing energy storage device is set up and related experiments on the proposed control strategy is performed. It is shown by the result that it has better power quality control capability.
