Optimal sizing of stand-alone hybrid wind/PV system with battery storage

Abstract

In this paper, a new methodology developed to design a hybrid wind/photovoltaic (wind/PV) system, is presented. Based on an optimization process using a deterministic algorithm, the developed methodology helps the authors to obtain the optimal number and type of PV panels, wind turbines and storage units ensuring that the system total cost is minimized while guaranteeing the permanent availability of energy to cover the load energy requirements. The hybrid system configuration and modeling are presented and the used deterministic algorithm (DIRECT algorithm) is described and implemented in MATLAB environment to optimize the hybrid wind/PV system.
