Hybrid Solar and Wind Power Generation with Grid Interconnection System for Improving Power Quality

Demand of electricity is growing very rapidly for industrialization & urbanization of India. Renewable energy sources being available abundantly in nature can be considered as a better option over conventional energy sources. Solar and wind energy are available in large amount and can be considered as reliable source of power generation. Hybrid solar and wind energy systems can be used for rural electrification and modernization of remote area. In this paper, simulation and hardware model of hybrid solar and wind power system connected to grid is done. For this analysis is carried out on simulated model to determine sag, swell, source voltage, source current, percentage of THD. The prototype hardware model of single phase is developed. Seven level inverter is used for converting dc power generated from solar into ac. The advantage of using seven inverter is used to improve the overall power quality of the system. The proposed system is simulated through math's laboratory simulation package and also design of seven level inverter studied. The hardware prototype model of the proposed scheme was also developed for single phase power system.
