Techno-economic Optimization of Hybrid Energy (Solar Photovoltaic and Wind) System for Rural Electrification

摘要

At present, standalone solar photovoltaic, wind systems have been promoted around the globe on comparatively larger scale. These independent systems cannot provide continuous source of energy, as they are seasonal Hence, energy storage systems will be required for each of these systems in order to satisfy the load demands. Usually storage system is expensive and the size has to be reduced to a minimum possible for the renewable energy system to be cost effective. Hybrid power system can be used to reduce energy storage requirements. A hybrid renewable energy system combines the generation of powerthrough solar and wind systems installed to meet the load demand of a particular location with adequate solar insolation and wind velocity. Two case studies are attempted at places Poompuhar and Ottapidaram located in Tamil Nadu, India. The model developed is used for design, analysis and optimizing of a hybrid system considering various location parameters. The effects of efficiency in the module, inverter and battery are studied. The effects of variation in number of days of autonomy, insolation and wind velocity on energy generation of the hybrid system is observed. The PV-wind hybrid option is techno-economically viable for rural electrification.
