基于异步迭代模式的电力系统分布式状态估计方法
Distributed State Estimation Method for Power Systems Based on Asynchronous Iteration Mode
摘要
Abstract
The integration of modeling and computation has made an obj ective demand on the distributed state estimation(DSE) for the safe operation of the interconnected power system.In order to provide a more accurate fundamental calculation model for the advanced application of distributed energy management system based on the asynchronous iteration mode,a new DSE algorithm based on asynchronous iteration mode is proposed to eliminate the power mismatch in traditional two-level state estimation.On the basis of equivalent network equivalents measurement correction ideology, a basic distributed state estimation algorithm is obtained by the construction of a fixed point iterative scheme for the boundary state.During the asynchronous iterative process,the external network equivalent measurement data are forced into a non-bad data set and the coordinated calculation is implemented with the external network measurements,thus the bad data close to the network boundary region will be identified.The proposed method is illustrated with the IEEE 1 1 8-bus system,and the results verify the validity.关键词
