 This paper proposes a new frequency regulation support strategy using a combination of a wind power plant, WPP, and a lithium ion battery. The WPP is used to provide primary frequency control support while the battery provides additional assistance when needed. The WPP is equipped with an adaptive gain frequency deviation loop which is dependent on the rotor speed and the difference in frequency. The battery is controlled based on its state of charge and the rotor speed of the WPP. A qualitative wake effect analysis was conducted to determine the feasibility of the proposed approach. The results showed that the minimum frequency point during a synchronous generator trip obtained a higher value than conventional ones in the suggested strategy.
