Modelling and Simulation of Fuel Cell Based DC Microgrid

Abstract

In the modern power scenario the deployment of distributed energy resources are gradually increasing day by day to find out the most suitable alternatives from the several choices of DERs. The natural uncertainty is inevitable in renewable energy resources such as solar and wind energy based systems. In this perspective, the Fuel Cell technology is considered as one of the promising DER which is almost free from the effect of climatic conditions. In this context, this dissertation presents a detailed literature survey on fuel cell technology and its promising applications in microgrid. This research proposes a model of Fuel Cell based DC microgrid supplying resistive loads and rotational machines such as separately excited DC motor using Matlab/Simulink software. This proposed model has the feature of critical and non-critical load selectivity which is an important property of microgrid. In addition, this work shows the scopes of future research on Fuel Cell based microgrid aiming maximum utilization of this technology as a part of solution to energy crisis in the near future.
