Performance analysis of protection technique for AC microgrid from symmetrical faults

Abstract

The research paper is presenting an implementation of Microgrid which assumes lots of loads & sources operated under a one controllable unit system providing power to the localized area. A microgrid model is built integrating wind energy, solar energy, diesel generator and residential load model and analyzing the impact of Renewable Energy Sources with microgrid on various quantities like active power, reactive power, current & voltage as shown and presented in the research paper during normal and fault condition. The various factors on which production of energy depends are PV farm’s size & it’s efficiency and speed of wind for Wind farm. The load is residential which has a consumption profile at given power factor. Highest solar intensity is during mid-day. The development of model is aimed to provide a sustainable energy supply to load without affecting the nature and compromising the needs of the future generation. In our research work we have used high-speed tripping protection technique for symmetrical faults.
