Summary:The paper envisages a novel algorithm for optimal location for placement of phasor measurement unit (PMU) ensuring complete power network observability. Based upon the network connectivity information, a two stage method has been proposed to keep the number of PMU's minimum in the network. In stage1, the PMU's are added starting with the highest valency bus whereas in stage 2 they are eliminated from less important buses while ensuring complete system observability. The proposed novel algorithm has been tested on various test systems viz. IEEE-14 bus, 30-bus, 57-bus and New England 39-bus system. On comparison with already known techniques available in literature, it was found that the algorithm designed in the present study is simple to implement and better in requisites of accuracy and computational speed.
