摘要
Abstract
In allusion to that traditional fixed partition method could not reflect changes of topology structure of power grid operation which may result in low calculation efficiency,this paper proposes a kind of new dynamic partition method which is based on physical topology structure of power grid operation and is able to gradually search all radial network partition, partition only with electrical connection lines and partition only with electrical connection node. The paper also proposes a kind of overall state estimation method based on sensitivity coordination of boundary node state quantity. By means of two examples,this method was proved to be able to rapidly respond to changes of topology structure of power grid,reduce af-fects on state estimation on other regions by errors of measuring data of some area and improve overall accuracy of state esti-mation on power grid.关键词
