Abstract In this paper, Integer Programming based methodology is presented for the optimal placement of Phasor Measurement Unit (PMU) that minimizes the cost of installation and provide the entire power system observability. The concepts of zero injection buses are used in this paper for further r eduction in number o f PMUs. Integer Programming may produce multiple results if neighboring buses to zero injection buses are not handled pro perly. Though a ll the results are correct but create confusion in selecting one of them. In order to mitigate this problem a criterion has been proposed in this paper to select the appropriate location of PMU in such circumstances. The proposed algorithm is tested on IEEE 14-bus, IEEE 24-bus and IEEE 30-bus systems. Keywords: Phasor Measurement Unit; Integer Programming method; Redundancy Measurement; Observability analysis. 1. Introduction In recent years, series of blackouts have been encountered in power systems. For secure operation of power systems, close monitoring of the system operating conditi ons is required. Today with the pr esence of Global Positioning System (GPS) it is quite possible to monitor the operation of power systems. This is traditionally accomplished by the state estimator which innate in the control centre computer and has access to the measurements received from different substations in the monitored system. These measurements are commonly provided by the remote terminal units (RTU) at the substations and include real/reactive power flows, power injections, and magnitudes of bus voltages and branch currents. More recently, synchronized phasor measurements have started to become available at selected substations in the system
