摘要

逆变型分布式电源能够在输出基波功率的同时对微电网中的谐波进行补偿，但是多个逆变型电源同时独立补偿存在交互影响问题。采用相对增益矩阵方法分析2个独立补偿逆变型电源之间的交互影响，并提出了一种多逆变型分布式电源协调控制的微电网谐波控制方法。首先选择微电网中的一个节点作为谐波控制的目标节点，然后将检测到的目标节点谐波电压相量分解，通过补偿量分配实现多逆变型分布式电源的协调控制。仿真实验结果证明提出的方法能够有效地协调多个逆变型电源对微电网中的谐波进行抑制。

Abstract

Despite the inverter interfaced distributed generator's capability of compensating for the harmonic current when outputting fundamental power，interaction takes place if compensation is made independently by multiple inverter interfaced distributed generators at the same time.A study is made of the interaction between two independent inverter interfaced generators using the relative gain array method，and a coordinated microgrid harmonic control method based on multiple inverter interfaced distributed generators is proposed.First，a bus is selected as the target bus of harmonic control in the microgrid.Secondly，the detected harmonic voltage phasor of the target bus is decomposed.Then the coordinated control for the multiple inverter interfaced distributed generators is achieved by allocating the compensation quantity.Simulation results show that the proposed method is able to effectively realize harmonic suppression in the microgrid by coordinating multiple inverter interfaced generators.
