OPTIMAL PLACEMENT OF PHASOR MEASURING UNIT IN POWER SYSTEM

This paper present different methods for optimal placement of phasor measuring unit (PMU) in power system for complete observability of the system. For smooth and efficient working of the system installation of phasor measuring unit become necessity. But due to high cost of PMU, it is not feasible to place it on every bus system. So, optimization becomes the crucial need. In present work for optimization power system toolbox (PSAT) is used. The proposed methods have been used and verified on IEEE-6, IEEE-9 bus system.
