Studying the impact of AC-microgrid on the main grid and it's fault analysis

This paper studies the advantages of using AC-microgrids and the impact of Distributed Generators (DG's) on the main grid by studying its voltage, power flow and calculating the losses in radial as well as meshed networks. For this paper, a grid of 4 houses and 3 DG's is modelled and simulated and the results were presented and analyzed. Fault analysis is conducted on the meshed system and the inferences were drawn. It is found out that due to the integration of Distributed Generators, the power is consumed locally and hence the active and reactive power losses in the system are also minimized. Based on the simulation results conclusions were drawn.
