A revised Matrix Manipulation approach for Optimal placement of Phasor Measure Units

This paper addresses the importance of Optimal placement of Phasor Measurement Units (PMUs) for complete system observability. PMUs are costly to install at every substation, therefore algorithms are developed to minimize the total required amount of PMUs for observability of the system at hand. The Matrix Manipulation Algorithm was developed for this purpose, yet proved to work well for small systems only. This Algorithm was revised and the revised version handles small and large systems well with minimal computational effort. In this paper it is tested and the results are compared with that of other algorithms to check the suitability of these algorithms for networks of different sizes such as networks with higher number of buses such as utility networks and those with smaller number of buses such as small microgrids. Basic Synchrophasor architecture and general functions thereof are aslo discussed.
