Optimal sizing of a PV/Wind hybrid system using pigeon inspired optimization

Abstract

This paper presents an optimal sizing study of a stand-alone hybrid PV/wind energy system (HPWES)with battery storage. The main objective of the optimization is minimization of the total system cost while satisfying the reliability constraint and maintaining the healthy charge on the battery. A relatively new optimization technique, pigeon inspired optimization (PIO) has been used to optimize the system. A break-even analysis has also been performed whether the wind/battery (WB) or a PV/wind/battery (PWB) system is more cost-competitive. The effectiveness of the proposed strategy has been verified through a case study and the results indicate that the PWB hybrid system is more economical when compared to the WB system.
