Limiting Use of Potential Energy Storage Compared to Batteries for a Lebanese Hybrid Wind/PV System

Abstract

In Lebanon, hybrid wind/PV systems are used to provide electricity when the public electricity is cut off. This paper treats the storage problems of electrical energy generated by the used renewable sources. A theoretical study on two types of electrical energy storage systems is given. These systems are the electrochemical energy storage devices (batteries) and the potential (or hydraulic) energy storage system. In order to find the limiting case of use between these two energy storage systems, economical study and comparison between them are discussed and analyzed.
