PSO algorithm for PMU placement on IRAN’s electricity grid considering system observability

Abstract: This paper utilizes different conventional algorithms for optimal placement of Phasor Measurement Units (PMUs) and compare them by testing on IEEE standard test cases with different number of buses. Two factor is considered in objective functions; first, the number of PMUs should be minimum, second, the number of observable buses in the systems should be maximized for total observability of the system. Ultimately, the PSO algorithm proposed for proper placement algorithm, and the real electricity grid of IRAN is applied to test the proposed algorithm. Results shows the efficiency of the proposed algorithm comparing to other methods and since the number of assigned PMUs to buses is approximately one third.
