Optimal Placement of Phasor Measurement Unit using Binary Particle Swarm Optimization in Connected Power Network

This paper suggested binary particle swarm optimization (BPSO) technique to place phasor measurement units (PMUs) optimally at suitable sites in a connected power network so that the connected power network can be fully perceptible. The goal of the suggested approach is to minimize number of PMUs as it is unwise to site PMUs at each bus to measure the state of connected power network as the PMUs and communication facilities are very expensive. The suggested method is applied on standard test systems such as IEEE 14, 30, New England 39 and IEEE 57-bus test system for optimal placements of PMUs with and without deliberation of zero injection bus. The outcomes compared with the existing standard results in literature. It is observed that the suggested approach ensures that the connected power network with minimum number of PMUs is fully observable.
