Optimal PMUs Placement Using Hybrid PSO-GSA Algorithm

This paper exposes a hybrid algorithm using particle swarm optimization and gravitational search algorithms to resolve the optimal PMUs placement (OPP), to achieve full observability of the power network. The principal purpose of the proposed technique is to reduce the total number of PMUs with and without zero injection bus and in the case of one PMU loss while improve the measurement redundancy. The proposed PSO-GSA has been applied to the IEEE 14, 30 and 57-bus.The outcomes show that the number of PMUs is similar to or less than the corresponding results of recently published papers, while the system topological observability is complete.
