Abstract
Phasor measurement units (PMUs) play a significant role in future smart grids for real-time control and monitoring. This reflects greater reliability and better stability and further increases the operating efficiency of power grids. It is better to determine the optimum placement of PMUs in power systems using the heuristic algorithm, which can solve the problem more efficiently and precisely in less time, compared with traditional techniques. This paper investigates the effect of varying GA parameters and operators on the overall solution of the problem of PMUs placement. Different population sizes, selection functions, and crossover and mutation rates are studied. As a case study, the IEEE-30 bus system is considered for the analysis. MATLAB SIMULINK is used for the modelling and simulation.
