This paper presents a procedure by which new PMU locations can be symmetrically determined in order to render an observable system. Monitoring and supervision of power systems are provided by the control centre, whose role is the design, coordination and network management. In this paper, an attempt has been made to control technique based on the implantation of measurement units at the network buses. A proposed methodology makes the system completely observable and calculates the optimal number of PMUs. In addition, the two different procedures have been applied to solve the PMU placement problem. One is an integer based programming (IP) method and the other one is a Genetic Algorithm (GA). A comparative study has been done by implementing both the methods to find the optimal number of PMUs. Once an optimal number of PMUs have been available, a load flow has been performed to know the bus voltage magnitude, if the bus voltage magnitude is within safe limit then the corresponding PMU will be operate otherwise not. The proposed methodology has been successfully implemented on three IEEE test systems.
