PROJECT TITLE :

Participation factor approach for phasor measurement unit placement in Power System state estimation

ABSTRACT :

This study focuses on the selection of the most effective location of phasor measurement units (PMUs) in the network for the aim of state estimation. The reduction within the error of the estimated states, that is, the quality improvement of the estimate, is the target used to pick out the foremost acceptable allocation of PMUs. The concept of participation of numerous states into the uncertainty of the error is applied to identify the foremost necessary states influencing the estimated errors. Unlike other strategies, the proposed technique considers all the elements of the state error covariance matrix and so addresses the impact of correlations between the errors. The effectiveness of the strategy has been demonstrated on the quality IEEE 14-bus and IEEE fifty seven-bus system models. The comparison of performance with other existing measurement placement techniques targeting the identical objective reflects the effectiveness of the participation issue-primarily based approach.
