Utilization of Thermal Energy Storage for reducing battery bank size of hybrid (wind-PV) systems

Abstract

Hybrid systems are becoming popular for remote area power generation applications. Any effort to decrease capital and operating costs, contributes to increase penetration of hybrid systems in power generation systems. In this paper combining of hybrid systems and Thermal Energy Storage (TES) has been proposed for lowering the costs of hybrid systems in hot climate. Since nowadays TES is known as an economical option in various sectors, therefore TES is selected for combining with hybrid systems. Optimization results show that, using TES in hybrid systems leads to significant reduction of the battery bank size or consumed fuel by backup systems like diesel generator. Therefore in hot climate, the hybrid systems which equipped with TES will be more economical than the conventional ones.
