An efficient and reliable system should have a real time process implemented in the distribution system which looks after the discrepancies in systems such as Phase differences in amongst the Voltages and Currents in the Power flow. PMUs are such units that provide a solution for the same. In this paper the minimization of PMUs using optimum placement techniques is implemented. For the same, Power System Analysis Toolbox in MATLAB is used and results are found better by 10-12% of cost saving. KEYWORDS: PMUs, Phasor, PSAT. I. INTRODUCTION In Past it is seen that many countries around the world were affected by power failures such as blackouts, which are caused by several reasons that may be inadequate power distribution system infrastructure and its maintenance or exponential electricity consumption growth that overstresses the power transmission and distribution system. Consequently, the power supply companies suffer from heavy losses and also impose inconveniency to private users and business customers. In order to prevent the frequent and blackouts, there is a dire need to invent such a technology that may be helpful in real time estimation of the state of a network. These technologies may be helpful in achievement of highly controllable and reliable networks for a greater stability of the power system network. A similar device that may be introduced for such a purpose is a Phasor Measurement Unit (PMU). PMU basically works on the synchronization of voltages and currents with a continuously available click frequency signal, that may be received from a global network such as geo – satellite or GPS systems. Integrating with the GPS receiver the base station may be able, to receive the synchronous data from each PMU in real time. A system may be of such a design that the location of the defect and problem over transmission can be identified in a real time and phase differences between different PMUs are detected. PMU: Phasor measurement unit is a unique combination of both hardware and software. The applications of PMUs were first published in 1980s. Virginia Technology developed first ever prototype of Phasor Measurement Unit (Phadke and Thorp, 2008), Macrodyne fostered the former PMU i.e. model ‘1690’ in the year 1992. The growth in the concern of governments over and around the world for climate changes and environmental alterations has forcedthem to make decisions on to produce, consume, and store energy. More specifically in view of existing framework and infrastructure established already in transmission, the requirement is on the transformation of our present electricity grids into smart grids, a step crucial for the successful uptake of renewable energy sources into the grid while reducing in the same time carbon dioxide emissions in the atmosphere. A smart electricity grid could be viewed as a copy of a traditional electricity grid (the attention is more focused here on the distribution grid compared to both production and transport grids as the former is more concerned with the uptake of renewable energy sources) with a communication structure capable of help maintaining the stability, the reliability and the quality of the grid in a context of interconnecting wide-area electricity networks II. METHODOLOGY In this research IEEE 24 bus test systems are taken for studying the various optimal PMU placement methods and comparing their results. Ideal number of PMUs & their location will be detected in the test bus system. To
