Frequency Regulation of Electric Grid with Wind Power Using Energy Storage System

The main objective of this work is to present energy storage technologies that are the best suited to mitigate wind variability and help balancing between generation and consumption. This work is dedicated to the study of storage technologies that can facilitate integration of wind energy as well as other resource of energy. Nevertheless, it is important to keep in mind that a single storage device can perform simultaneously several functions and consequently be used for several applications. For example, an energy storage system associated with wind generation could be used both for "frequency regulation reserve" and "wind energy time shifting". Several cost-benefit studies show that a storage device has to perform simultaneously several functions to be cost effective.
