Generation scheduling with integration of wind power and compressed air energy storage

Abstract

The use of energy storage integrated with wind power is commonly considered in a system for increased operational flexibility. In past years, a fast growth in development of wind generation has been experienced in power system, due to many factors including environment and depletion of fossil fuel resources. With increasing installed wind capacity, the intermittency issues must be addressed. One way to mitigate the intermittency of wind generation is energy storage. In this paper, we study compressed air energy storage (CAES) as an alternative solution to deal with intermittency in wind generation. We present a formulation of security-constrained unit commitment (SCUC) problem with emphasis on integration of wind power and CAES. Case studies with eight-bus system are presented in detail to validate the proposed model.
