Hybrid Energy system (HRES) combines two or more renewable energy sources used together to provide increased system efficiency as well as greater balance in energy supply. It becomes popular to remote area for power generation due to advances in renewable energy technologies and subsequent rise in prices of petroleum products. Hybrid energy system is an excellent solution for electrification of remote rural areas where the grid extension is difficult and not economical. [29] Such system incorporates a combination of one or several renewable energy sources such as solar photovoltaic, wind energy, micro-hydro and may be conventional generators for backup. Hybrid energy system has found much wider dimension than individual stand-alone renewable/conventional systems for rural remote electrification. It is a known fact that the application of hybrid energy system based rural remote area electrification will offer a quick, economic and reliable answer to the rural household‘s need for power, especially, for those of light duty appliances. However, the planning of rural remote area electrification is not always easy and a proper mix can be arrived at only after a careful technical, economic, and socio-economic study of the region involved. In order to evaluate techno-economics of any hybrid energy system configuration, it is necessary to develop a proper model for optimization and simulation. A range of hybrid configurations are possible, however, the choice must suit the
