The Improvement of Weighted Least Square State Estimation Accuracy Using Optimal PMU Placement
Authors: , ,
Abstract: This paper proposed a new technique to improve the state estimation performance by optimal placement of phasor measurement units (OPP), the proposed technique is based on Simulating Annealing (SA) algorithm for OPP by comparing between the SA solution sets and choosing the optimal location of PMUs to enhance the state estimation performance. The proposed technique has been tested through IEEE 24 bus test system using power system analysis toolbox in MATLAB program. In this paper the root mean squared deviation (RMSD) has been used to determine the state estimation performance, the simulation result demonstrates that the proposed method proved its effectiveness to be one of the best methods used to improve the state estimation performance
