Abstract

The term ‘micro’ means small; grid means ‘a network or a matrix’. Many such small networks, centrally supervised and interconnected to form a self-generated power called the Micro-grid. For a pervasive Green energy to exist, three probable solutions are taken into account; generation, economy and sustainable power generation. Sustainable power generation utilizes the renewable resources and hence are more environment friendly with lower carbon footprints. The key objective of this work is to model a self-sustained Micro-grid from the existing Indian distribution feeder, which means a small scale interconnected, centralized single controllable system where the particular region is supplied with distributed energy resources like solar and wind instead of the main grid. In this work, the existing system, implemented in PSCAD, is taken from the Indian Distribution Feeder, which comprises of 2 regions each supplied with 100 KVA transformers. One region is 33 bus systems and the other region is 38 bus systems. They are taken as two separate MGs and these further are split into two sub MGs producing a total of four MGs altogether. Distributed energy sources like wind, solar and diesel are designed individually and interconnected finally to make up a Standalone MG. The results are obtained in PSCAD software package.
