配电网中基于网络分区的高比例分布式光伏集群电压控制
Network Partition Based Cluster Voltage Control of High-penetration Distributed Photovoltaic Systems in Distribution Networks
摘要
Abstract
With the access of high-penetration distributed photovoltaic (PV) systems,the problem of overvoltage in the distribution network is becoming increasingly serious.The conventional centralized voltage control methods for all PV systems have become too complicated to meet the requirements of controlling the time scale.By referring to reactive/active power balance index and the coupling index of area nodes,this paper proposes an improved modularity partition algorithm,which can automatically divide a distribution network with high-penetration of distributed PV systems into optimal partitions of reactive and active power layer.And then,PV systems are divided into clusters.Based on the partition,the voltage control strategy of using reactive power first and active power second lies in controlling the key PV node to regulate the voltage of key load nodes within a partition,effectively narrow the search range of controllable PV systems and greatly reduce the number of controlled nodes to accelerate the completion time of control.Finally,a certain 10 kV actual feeder system is used as an example to prove the effectiveness and feasibility of the proposed method.关键词
