###### Abstract  
Wind curtailment and inadequate grid-connected frequency regulation capability are the main obstacles preventing wind power from becoming more permeable. The electric hydrogen production system can tackle the wind curtailment issue by converting electrical energy into hydrogen energy under normal operating circumstances. It can be applied as a load-reducing method during frequency regulation to help the system restore the power balance. First, this study proposes the concept of a hybrid plant station that combines the production of hydrogen and wind energy. This plant station will be referred to as a hybrid station with centralized hydrogen production and distributed energy storage. By mimicking the synchronous generator's frequency control features, the primary frequency regulation mechanism of a hybrid plant station is examined. Secondly, due to the frequency regulation requirements of the power grid's full-time domain hybrid power station, this paper proposes a hybrid plant station control strategy based on the EEMD variable parameter control algorithm. In frequency regulation power, the electric hydrogen production device load reduction responds to the low-frequency component, and the supercapacitor responds to the high-frequency component. The impact of the dynamic characteristics of alkaline electrolyzers on the frequency regulation effect is analyzed in this article, along with a comparison of the matching of various energy storage devices and electrolyzers in power grid frequency regulation. Finally, the feasibility and soundness of the proposed control strategy are confirmed by creating a simulation model representing a hybrid plant station involved in primary frequency management under various operational scenarios. d 2023 13 12394 13 November 2023 16 November 202  
grid-connected wind turbines should possess the same frequency control capabilities as synchronous generators [6]. Previous research has shown that wind turbines are coupled with the system frequency through additional control and have frequency regulation capabilities [7; 8]. References [9; 10] suggested a way for wind turbines to react to variations in system frequency by adjusting the rotor kinetic energy and simulating the frequency regulation features of synchronous generators. However, this control method is affected by the status of the wind turbine and cannot provide stable power for frequency regulation. References [11; 12] by adjusting the rotor speed and pitch angle, reserve power for system frequency management; nevertheless, this increases the system wind desertion rate at the expense of the MPPT state. A multi-machine collaborative frequency regulation control strategy was proposed by [13; 14]. The control system is complicated, and the wind turbine operating status may be more consistent given the wind power aggregation effect. Simultaneously, existing research has suggested using wind turbine energy storage devices as power absorption elements to fulfill the system's frequency regulation needs [15]. The distributed energy storage architecture is provided by [16]. The DC-DC converter connects the energy storage device to the wind turbine DC bus. References [17; 18] examine the collaborative wind turbine energy storage device's frequency regulation features and suggest a wind storage combination control technique for frequency regulation. Reference [19] suggests using the energy storage device in conjunction with the extra control of the wind turbines to aid in the recovery of the system frequency. On the other hand, an energy storage device alone has a large frequency regulation capacity at a high investment cost. Wind electricity hydrogen production provides a new reference for wind turbine grid-connected frequency regulation [20]. Under normal working conditions, the power-to-hydrogen (P2H) device consumes electricity and hydrogen production to improve the absorption capacity of wind power, and the hydrogen generated can supply the hydrogen downstream industry and improve the system economy [21].
