Performance evaluation of a hybrid wind-diesel-compressed air energy storage system

One of the main concerns of hybrid power system is the fluctuation of voltage and frequency of the system due to variation in the load and renewable power. A number of different types of energy storage techniques, which are theoretically and operationally available, have been proposed to remedy such fluctuations. One long-term storage option is compressed air. In this paper, the effects of the working pressure and system design of a typical compressed air storage system on the overall performance of a hybrid system is investigated. The model of a hybrid wind-diesel-compressed air generating system is developed and simulated using MATLAB. It is shown that the energy storage system and the proper sizing of the same play a vital role in increasing the renewable energy penetration.
