考虑集群划分的分布式光伏无功电压控制策略
A reactive voltage control strategy for distributed PV based on cluster segmentation
摘要
Abstract
In response to the voltage over-limit in distributed photovoltaic(PV)distribution networks,a reactive voltage control strategy considering cluster segmentation of distributed PV is proposed.Firstly,a modularity index based on reactive voltage sensitivity is introduced;taking account of the reactive balance and coupling within clus-ters,an improved modularity index is obtained and used for cluster segmentation.Then,a strategy for reactive volt-age control within over-limit clusters and a coordinated control strategy between clusters are proposed.When over-voltage clusters cannot restore voltage to a safe level internally,the strategy involves selecting lead nodes from safe clusters with adjustable reactive power capacity to allocate the remaining adjustable reactive power capacity to the overvoltage clusters.Finally,simulations are conducted using an IEEE 33-bus distribution network to validate the effectiveness of the proposed strategy.关键词
