Abstract :

This paper presents analytical method to find optimal location of PMU to make power system observable. This Optimal PMU Placement (OPP) is optimization problem which has been solved using BILP (Binary Integer Linear Programming). The analytical method has been coded in the MATLAB and applied to different IEEE test systems up to 118 buses. Moreover OPP is offline optimization problem. The method has also been implemented for certain contingent conditions like line outage and PMU failures. The number of PMUs required is almost one third of system buses however their numbers actually depends on the topology of the network.
