Dynamic control of energy storage system for stable operation of wind power plant

In this paper, to ensure stable operation of a wind power plant augmented with energy storage, dynamic control for energy storage system (ESS) inside the wind power plant is investigated. Control structure and control parameters of ESS are selected based on proposed small-signal stability criterion and large-signal stability criterion. Simulation result shows that with proposed dynamic control scheme for the ESS, the wind power power plant is stabilized when grid behaves as a constant power load which becomes a destabilizing factor, or when there is failure of wind turbine.
