Abstract: A modified Invasive Weed based methodology for optimal measurement of Phasor measurements units (PMUs) for complete observability of Power system is presented in this paper. The prime objective of this Optimization problem is to reduce the number of PMUs and to maximize the redundancy at power system bushes. In this paper MIWO (Modified Invasive Weed Algorithm is implemented for three bush systems namely 7, 9, IEEE 14 standard bus systems. The proposed algorithm is very easy to understand and it’s result is as satisfactory as results of other algorithm methods.

Keywords: Invasive Weed Algorithm, Phasor Measurement Units, Observability, Optimal Placements.
