摘要利用逆变型分布式电源对微电网中的谐波、无功功率和不平衡进行补偿是一种有效的微电网电能质量管理方法。本文分析了谐波源不在分布式电源接入点情况下进行补偿时补偿效果的影响因素,并在此基础上提出了一种微电网中基于逆变型分布式电源控制的重要节点电能质量管理方法。该方法选择逆变电源附近重要程度最高的节点并以其为目标对微电网的电能质量进行管理,充分利用微电网中现有设备提高整体的电能质量。此外,本文提出的方法还能够根据实际需要灵活地选择补偿目标节点和补偿水平,具有重要的实际意义。仿真结果证明了本文提出方法的有效性。

Abstract：It is a kind of effective method for power quality management in microgrid that with distributed inverter source the harmonic, reactive power and unbalance are compensated. The influences that harmonic sources are absent in access point of distributed source are analyzed. With such basics, a method to manage power quality of important node based on distributed inverter control in microgrid is proposed. In this paper, the most important node objected nearby the inverter is chosen to control power quality, and the existing equipment are used to improve power quality of microgrid integrally. Furthermore, there is practical significance for this new method which can choose the target node and compensation level flexibly. The simulation results show the availability of the proposed method.

Key words： Microgrid distributed generation power quality inverter control harmonics compensation
