Electrical Energy Storage System for Wind Turbines

Energy storage devices and solutions are required for power quality and balance within wind systems. In the context of rapidly expanding of distributed energy sources, the wind energy converters are in the center of interest. In this case, the direct dependence of the power generation capability for a given wind speed represents a major problem of wind energy conversion with regard to large-scale network integration. This paper proposes an overall solution which consists of a wind plant with a smart Storage Modular System (SSMS) where the wind source -as stochastic oneis coupled over a dc bus with two storage modules and a smart grid interface.
