With the increasing demand of Renewable energy, Hybrid Renewable Energy Sources (HRES) has been used widely in the remote areas. HRES involves combining of the two renewable energy sources with the aim of providing higher energy efficiency along with the greater energy output. In case of providing higher output load, we can combine the two renewable energy sources resulting to the 100% efficiency. To implement the HRES system there should be a well-defined standardized set of frameworks such as demand assessment, covering areas, resource assessment and the barriers. Some common configurations used in the HRES are:
PV/Wind/diesel generator HRES,
PV/wind/fuel cell HRES
Biomass/wind/diesel generator HRES
PV/Wind/Biomass/fuel cell HRES
For ensuring continuous supply of power to the load there has to be critical storage technology. There are many types of energy storage that can be used in hybrid renewable energy system for example, compressed air energy storage (CAES), Pumped hydro storage (PHS), hydrogen fuel cells, flywheels, supercapacitors, superconducting magnetic energy storage (SMES) and batteries.
