An Integrated Hybrid Power Supply for Off-Grid Applications Fed by Wind/Photovoltaic/Fuel Cell Energy Systems

This paper introduces a method to unit sizing hybrid wind/Photovoltaic/Fuel Cell generation system for a typical domestic load that is not located near the electric grid. In this configuration the combination of a battery, an electrolyser, and a hydrogen storage tank are used as the energy storage system. The aim of this design is finding the configuration, among a set of systems components, which meets the desired system reliability requirements, with the lowest value of levelized cost of energy over 20 years of operation. An energy based modelling has been developed using Matlab-Simulink to observe evolution of the system during a typical day, and the results are reported and discussed in the paper.
