DESIGN &COST OPTIMIZATION OF WIND –SOLAR HYBRID POWER SYSTEM

Abstract

Hybrid solar PV and wind generation system become very attractive solution in particular for stand-alone applications. Combining the two sources of solar and wind can provide better reliability and their hybrid system becomes more economical to run since the weakness of one system can be complemented by the strength of the other one. The integration of hybrid solar and wind power systems into the grid can further help in improving the overall economy and reliability of renewable power generation to supply its load. Similarly, the integration of hybrid solar and wind power in a stand-alone system can reduce the size of energy storage needed to supply continuous power. Solar electricity generation systems use either photovoltaic or concentrated solar power. The focus in this paper will be on the photovoltaics type. Electricity from solar PV and concentrated solar power plants is significantly expensive and requires significant drop in cost or change in policies by either subsidizing or forcing the use of these technologies to be able to achieve significant market penetration. The output can be extracted from both solar as well as from wind too. To perform this project long mathematical analysis has taken in to consideration and the design and simulation is done on Homer software. Finally, we proposed that standalone system (solar/wind/ battery) is economically feasible and environmentally friendly to replace the existing diesel-only power supply system for Lenda town, Ethiopia.
