Fault analysis on a smart grid

Abstract

With the finite amount of non-renewable energy resources nearing their end, and their negative effect on the environment rising, the world needs to start integrating more renewable energy sources into pre-existing systems and developing smart grids. This addition of clean energy sources to the system will be studied to determine whether their integration will improve the system or not. For testing purposes, a solar farm and a wind farm were chosen as the integrated systems. The benchmark for this simulation will be the standard IEEE 9 bus system which will be subjected to multiple fault cases, such as transmission line fault, and sudden increase and decrease of a load. Each fault case will occur on the grid as a standalone system and with both cases of solar and wind integration, and load flow analysis will be done for each fault scenario in order to compare the results and confirm improvement.
