Abstract: Wind power tends to be unsteady because it is influenced by natural and meteorological conditions, so, there is a need of energy storage system that takes care of this wind power variation. The integration of a battery energy storage system (BESS) with a wind turbine doubly fed induction generator (DFIG) can make this intermittent in wind power more dispatchable. This paper focuses on the development of a control strategy for optimal use of the BESS for this purpose. Two objectives are targeted in the paper. The first objective is to obtain the maximum output power of the existing wind regime. The second objective is to supply the demand power commitment to the grid. This is achieved by controlling the battery power flow. The size of the battery is calculated to accommodate excess power and to compensate for the deficit power according to the wind regime and the grid power demand.

Keywords: wind energy; doubly fed induction generator; DFIG; battery storage; power coordination; wind power; control strategy; battery energy storage system; BESS; wind turbines; battery power flow; power flow control.
