基于节点搜索的网架重构方法
Network-Reconfiguration Scheme Based on Node Search
摘要
Abstract
The modelling method based on line break state for complex power system network-reconfiguration has the problems that the dimension of optimization problem is too large and searching the target network may result in redundant results.Aiming at these problems,this paper proposes a modelling method with taking node recovery or not as state variable.The method takes the nodes in the power system as the search object,and obtains the unique sequence of recovery nodes through optimization.The target network can be obtained by connecting lines between those recovery nodes selectively,which meets the conditions of constraint,namely topological connectivity,safe and stable operation constraints.Meanwhile,according to the drawback of existing method for network connectivity assurance,this paper proposes a target network selection method based on Dijkstra algorithm,and verifies the validity of the proposed method with taking IEEE 118-bus system and a regional power grid as examples.关键词
