Investigating and Comparing the Simulation of Protection Networks and Their Performance Improvement in Power Systems

Abstract

Nowadays, Phasor Measurement Units (PMUs) are used in power systems to improve the speed and accuracy of network protection and control systems. The optimal placement of these devices in the system is very important due to their high purchasing and installation costs. This study investigates the Optimal PMU Placement (OPP) problem in the system using a binary particle swarm optimization (BPSO) algorithm and MATLAB. Besides, constraints such as alternative measurement, zero-injection bus (ZIB), and traditional measurement constraint (SCADA (Supervisory Control and Data Acquisition)) are considered in the objective function of this study. This study used the system topology method to simulate the IEEE57 BUS, IEEE30 BUS, and IEEE14 BUS networks and implemented the objective function on these systems. The results showed that the entire system remained observable as a result of PMUs being installed in less than 25% of the buses. Finally, the results of this study were compared with those of similar work.
