ABSTRACT
This paper deals with a study carried out to determine the optimal locations of phasor measurement units (PMUs) for a given power system. Power systems are rapidly becoming populated by PMUs as they provide valuable phasor information of voltages and currents for protection, operation and control of power systems during normal and abnormal operation. This paper focuses on the use of PMU measurements in state estimators. The principle objective was to investigate methods of determining optimal locations for PMUs so that the entire power system is observable. The recently developed AI techniques, like Genetic algorithm and artificial bee colony techniques are applied to find out the optimal placement of PMUs for various systems. It is found that the entire system can be made observable by strategically placing PMUs at one-third of the system buses for a given system.
