摘要/Abstract

摘要： 为解决配电网中分布式电源(DG)高比例渗透引起的电压偏差问题，提高系统电压稳定性，提出一种DG并网逆变器和电压检测型有源滤波器（voltage detection based active power filter，VDAPF）参与电压治理的SVG优化配置策略。采用分区思想，提出基于社团理论的分区方法，选取各区域的主导治理节点作为SVG候选接入节点；建立SVG总投资成本最小和系统电压偏差治理效果最优的多目标SVG优化配置模型，并采用改进的遗传算法对配置模型进行求解；考虑DG并网逆变器和电压检测型APF剩余容量的不确定性，采用多场景分析技术构建一系列电压治理运行场景。以IEEE 33节点配电网结构为算例进行分析，验证了所提优化配置策略的有效性和合理性。

Abstract: To solve the voltage deviation problem caused by the high penetration of distributed generation (DG) in the distribution networks, a strategy is proposed for optimal allocation of static var generator (SVG) with consideration of voltage mitigation of DG grid-connected inverter (GCIN) and voltage detection based active power filter (VDAPF). Firstly, a partitioning method based on community theory is proposed. And then, the dominant nodes in each region are selected as the candidate nodes of SVG to be installed. A multi-objective SVG optimal allocation model is established with minimum total cost of SVG and optimal mitigation effect of system voltage deviation, and the improved genetic algorithm is used to solve the allocation model. Considering the uncertainties of the remaining capacity of GCIN and VDAPF, the multi-scenario analysis technique is adopted to construct a series of voltage mitigation operation scenarios. A case study of the IEEE 33-bus distribution network is conducted to verify the effectiveness and rationality of the proposed strategy.
