A case study on optimal phasor measurement unit placement for emerging Indian national smart grid

India is on the way for transforming its power grid to a modern, intelligent grid called Smart grid. It can transform the Indian power grid to an efficient, reliable, resilient and eco-friendly power system network. The present Indian power grid has to undergo major reformations in wide areas like control methods, communication technologies and monitoring systems to achieve the goal of Indian national smart grid. In this regard, it is essential to incorporate phasor measurement units (PMUs) in power grid monitoring system. The higher financial burden owing to PMU placements across the grid invites the researches for its optimal placement that deliver complete observability of the grid. This paper deliberates optimal locations for PMU placement in Indian power grid for achieving complete observability. Simulated annealing approach is adopted in this paper for optimizing the PMU locations to attain complete observability.
