The energy demand in the modern power system is increasing day by day. Thus integration of microgrid with the conventional grid can fulfill the high power demand but it can cause many changes in the power system. In this paper, a real valued Damodar Valley Corporation (DVC) grid connected microgrid system is formed with the help of Power System Analysis Toolbox (PSAT) software and analyzed the performance by Continuous Power Flow (CPF) method. A three phase short circuit fault is also introduced in the main grid and voltage profile is observed. It is also observed that the voltage profile of the faulty system is improved when a microgrid is connected with that main DVC grid system. [ABSTRACT FROM AUTHOR]

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]
