Abstract：With the emerging frequency security problem of power systems, the application of quick response energy storage devices to the primary frequency control is an effective measure to ensure frequency security. This paper proposes a control strategy for primary frequency regulation with the participation of a quick response energy storage. The core idea is to design a whole transfer function based on the expected frequency response of the system and to design a primary frequency control strategy of the energy storage based on the whole transfer function. The demand for energy storage capacity is minimized with the optimization of the parameter. The control strategy is beyond the frame of traditional integrated inertia control and thus has a wide universality. The proposed strategy is applied in a simplified system to minimize the maximum frequency difference with the goal of obtaining a frequency response curve without overshoot. Results of the study verify that the control strategy proposed in this paper can significantly improve the frequency response characteristics compared with the traditional integrated inertia control strategy.
