The role of the microgrid to meet up the localized power demand is of immense importance considering the growing power demand as well as grid inadequacy in Indian power scenario. Apart from meeting localized power demand with various distributed generating sources microgrid can render support to the adjacent main grid or similar localized grid as when needed. This paper presents the techniques for identifying placement sites for Phasor Measurement Units (PMUs) in a microgrid system based on complete observability of the system. The main objective of optimal placement of PMU problem is to determine a minimal set of PMUs such that the whole system is observable. This study has been done on a 14 bus test model with the help of PSAT. [ABSTRACT FROM AUTHOR]
