Abstract

Improvements in power system control and protection is achieved by utilizing real time synchronized phasor measurements. The trend in recent years is the steady increase of Phasor Measurement Unit (PMU) installations worldwide for various applications those targeted for State Estimation enhancement. This paper solves the optimal placement of phasor measurement units for complete observability using Integer Linear Programming (ILP) solution methodology. ILP is used to determine the optimal number and location of PMUs needed to make the network completely observable. This method is tested on Thirunelveli network and complete system observability after placing optimum number of PMUs has been verified.
