Wind power integrated with compressed air energy storage

Global concerns over climate change and sustainability have led to recent worldwide push toward generating electricity from renewable and sustainable resources. Wind energy is a fast-growing form of renewable resources worldwide. Integration of wind resources into the power system brings new challenges to the planning, operation, and control of power system in either short-term or long-term time interval. It´s an intermittent resource, which is not dispatchable in the traditional sense. Fortunately, a number of new technologies are making wind energy friendly, and promising continued growth in its share of total energy. These include better wind forecast, advanced power electronic devices, enhanced control techniques and energy storage. In this paper we discuss compressed air energy storage (CAES) as an alternative solution to store energy. After giving an overview about wind energy and CAES technology some CAES power plants in the world will be introduced and the integration of CAES with green power plant will be evaluated.
