Optimal Placement of Phasor Measurement Units for enhancing Observability of Power Systems by Using Genetic Algorithm

With the increasing expansion of power grid in the recent years, the need for new monitoring and controlling systems for better control and exploitation of power systems, is felt more than ever. In the meantime, the use of synchronous phasor measurement units (PMU) has recently attracted the attention and interest of the researchers and designers of power grids. These units, by measuring the voltage and current phasor with high-speed, provide the conditions for accurate and real-time observability of the system. The important point here is that the necessary condition for the full observability of the power system is the optimal placement of these units in the power grid. In this paper, the primary objective is the optimal placement of the PMU units in a conventional power grid by using genetic algorithms to enhance the observability of the system; then, in the end, by comparing the results obtained from the proposed method with other conventional methods, the efficiency of the model is assessed.
