基于集群划分的含高比例户用光伏配电网电压控制研究
Research on voltage control of distribution networks with high-proportion household photovoltaics based on cluster division
摘要
Abstract
In a distribution network with a high proportion of household photovoltaic access,changes in source and load characteristics lead to numerous over-limit voltages,necessitating an effective voltage control method for distribution networks.In this study,a comprehensive division index,considering electrical modularity index,coupling degree index and power balance index,was established to realize the cluster division of a distribution network with a high proportion of household photovoltaics.Among the nodes with energy storage systems in each cluster,key control nodes in each cluster were selected using active-voltage sensitivity.Considering energy storage for voltage regulation,under the constraints of energy storage charging and discharging operations,a voltage control model based on cluster division was constructed with the minimum voltage deviation and network loss as the objectives.According to the power demand of the clusters containing the nodes with over-limit voltage,the energy storage systems at the key control nodes were preferentially regulated to realize effective voltage control.The IEEE 33 node system with a high proportion of household photovoltaics and energy storage system access was analyzed to verify the effectiveness of the voltage control method for the distribution network based on cluster division.关键词
