Résumé

In most remote areas, the diesel generator is the main source of electrical energy. For these regions, the price in extending the electricity grid is very prohibitive and the remoteness highly majors the fuel price. Paradoxically, most of these communities are situated in regions characterized by sufficient wind resource for a commercial exploitation. The use of wind-diesel hybrid system (WDHS) in these autonomous networks could reduce the operating deficits. However, the profitability of the WDHS is reached at the condition of obtaining a high penetration of wind energy (PRWE) which is only possible through the use of storage systems. The compressed air energy storage (CAES) is one of several technologies that can be used with WDHS. In this paper, two case studies will be presented to demonstrate the numerous advantages of CAES for hybrid wind-diesel systems.
