Abstract This paper presents an optimal placement of Phasor Measurement Unit model considering measurement redundancy using real coded genetic algorithm(RCGA) for state estimation. This model ensures complete observability of power system for normal conditions as well as contingencies considering Zero injection measurements. Single PMU outages and single branch outages are the contingencies considered in this paper. The optimum solution is obtained by considering objectives such as minimum number of PMU and maximum redundancy. The New England 39, IEEE 57, IEEE118 and practical networks of Indian Grid such as Western regional Indian Power Grid and Northern regional Indian Power Grid are considered for the optimal placement of PMU and it provides verification of globally optimum solution of the proposed model.
