Integration of wind farm with compressed air energy storage

Abstract

This paper proposed two methods to reduce the intermittent nature of renewable and makes it dispatchable by integrating wind farms with energy storage systems. In the first proposed method wind farm is integrated to grid and electricity of wind farm is used to drive the compressors to generate compressed air. With the second proposed method wind farm is totally separate from the grid and still generating compressed air by placing the compressor on the nacelle of wind tower. Energy is stored in underground caverns in the form of compressed air or in high pressure pipelines which is called compressed air energy storage (CAES). An analysis considering economically and technically aspects is made. A comparison of two hybrid systems is also made.
