Design and Simulation of Small Scale Microgrid Testbed

Microgrid systems is a new technology for improving reliability and providing alternative energy supplies to the grid system. Low voltage faults in the system are one of the critical issues that require distributed generating sources to disconnect from grid provide energy to the load. Therefore the techniques used in the micro grid system with micro sources can be important in reducing the problems in the grid system. In this paper two different micro sources photovoltaic (PV) and wind turbine (WT) with battery storage for a small scale micro grid system are simulated. The aim is to observe the effect of micro sources parameter on the outputs at the point of common coupling. Most of the results can be used for develop a small scale micro grid system for practical applications.
