A Literature Review on Minimizing the number of Phasor Measurement Units (PMUs) and their Optimal Placement in Power Systems

Ketanpreet Kaur


This paper compares 12 methods of optimization techniques for the optimal placement of phasor measurement units (PMUs) in power systems. These techniques are further explained for minimizing the no. of pmu’s in the real time power system. The planned methodology result in a reduction in the number of PMUs even though the system topological observability is complete. First, the number of PMUs is minimized in such a way that the system topological observability is complete. The optimal placement is also done to maximize the measurements redundancy which allows a bus to be observed more than one time. All these methods are categorized under Mathematical Programming Methods, Heuristic Methods and Meta-Heuristic Methods have been discussed.
