complement each other. During the period of bright sunlight, the solar energy is utilized for charging the batteries, The Meaning creating of Sufficiency enough Economy energy reserve to be drawn during night, while the wind turbine produce most 250of the International energy during Conference monsoon when solar power generation is minimum. Thus the hybrid combination uses the best of both means and can provide quality, stable power supply for sustainable development in rural areas. These systems are specifically designed to draw 48 volts DC power output from the solar cells/ wind turbines and combine them to charge the storage batteries. The system does require availability of diesel generator, though for much reduced number of hour’s operation. It is also designed to give priority Figure to solar I: and Solar-Wind wind power Hybrid so that operations System of with generators Diesel can Generator be minimized and to the extent possible Battery Bank Back-up Figure I: Solar-Wind Hybrid System with Diesel Generator and Battery Bank Back-up Biomass hasn’t Biomass figured hasn’t much figured in research much studies in in research combination studies with in Solar combination PV-Wind Hybrid. with Solar Hence, it becomes PV-Wind imperative Hybrid. to assess Hence, various it becomes renewable imperative energy based to assess local various solutions renewable of alternative energy energy generating based electricity local solutions at the community of alternative level.

Methodology generation solutions and compares them with an optimized proposed model which is a hybrid of the above solutions. A conceptual model consisting of hybrid of Solar PV, Wind and Biomass technologies along with electricity demand. Biodiesel generator backup has been proposed to meet the local electricity demands as an alternative to centralized conventional mega power generating projects’ scheme. Figure II illustrates the concept as a Sufficiency Economy Development Initiative. 2.
