A Literature Review on Optimal Placement of PMU and Voltage Stability


In the present scenario, it is difficult to manipulate the nature of the power system which makes the system unstable. Therefore, real time monitoring is needed for checking out the possible outcomes of the failure in the system. Hence Phasor Measurement Unit (PMU) proves to be promising device as its gaining importance for its wide area application in real time which will be beneficial from both these aspect i.e reduction of contingencies and improving security system. This paper focuses on the various optimal placement techniques of PMU, discusses about the voltage stability and shows some of the real time applications of PMU.

Keywords: Global Positioning System (GPS), Phasor Measurement Unit (PMU), Observability Optimal Placement of PMU (OPP), State Estimation, Voltage Stability
