MANAGEMENT AND CONTROL OF A WIND-DIESEL HYBRID SYSTEM FOR ISOLATED SITE ELECTRIFICATION

Abstract

The Algerian south is very vast where the presence of a broad community seen far from the electric distribution several hundreds of kilometers .Currently the power is provided by generators for domestic consumption and the pumping for irrigation of farmland. This solution is not beneficial in the long term from the economic and technical point of view where the integration of a hybrid system will be useful by the diet based on wind power will be interesting because the wind speed covers the majority of these sites throughout the year as the city of Adrar. This article examines a strategy for the management of a system ensuring optimum use of renewable energy in a System of Energy Hybrid (SEH) using a wind turbine, a diesel generator and a battery storage system as bank representing a technology which the technical - economic aspects will be more profitable. Operating conditions depend on performance and weather conditions (wind speed, temperature, terrain) which have an influence on the performance of the wind turbine but the characteristics of other equipment (rectifier, inverter, controller, type filter, etc...); for this reason we present in this paper a suitable management of a hybrid system (SEH) having a strategy to balance the exploitation of these sources, and the permanent transfer of energy between the source and the load ensuring a continuity of adequate appreciable service at an economic cost.
