Modeling and Simulation of a Wind-diesel Hybrid Power System for Isolated Areas

Abstract

In many isolated areas situated in south Algerian, the diesel generators are the major source of electric energy. Indeed, the alimentation power of these remote areas still poses order problems (technical, economical and ecological). The electricity produced with the help of diesel generators is relatively inefficient, very expensive and responsible for the emission of greenhouse gas. These isolated areas have significant wind energy potential; which puts him in good position for the exploitation of clean and sustainable wind energy. The use of Twinning Wind-Diesel (TWD) is widely recommended especially to reduce operating deficits. However, the profitability of TWD is attained the condition to obtain a high penetration ratio of wind energy: which is possible only when using energy system storage. For hybrid energy storage systems plays a vital role, different storage technologies, we chosen for our study the battery energy storage system (BESS) still represent the most cost-effective technology. The subject of this paper is to present the modeling of a Wind Diesel Hybrid System (WDHS) comprising a Diesel Generator (DG), a Wind Turbine Generator (WTG), the consumer load, a Ni-MH Battery and a Distributed Control System (DCS).
