Performance analysis of a grid connected microgrid system under fault condition.

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]
