Abstract

The advent of PMU-based WAMS provides a chance to improve the traditional state estimation, AC load flow model innovation (network) graph state estimation based PMUs is a new but effective estimation algorithm. By using it, this paper carries out process-oriented state estimation using all the measurements within a period of time, which can provide characteristic states within a process of time. In order to develop the new method, the operating process is divided into several processes and sub-processes according to the topology change. In each process or sub-process, a characteristic state is derived which can represent the average status of this process or subprocess. In order to compute the expected states, an expected innovation network graph is derived. The IEEE-5 bus system is used to illustrate the effectiveness of the new method.
