###### Abstract
In frequency regulation, P2H devices can be used as a large-capacity, controllable load to participate in system frequency regulation through load reduction [22]. The energy storage device quickly compensates for the power when the load changes abruptly and assists in the frequency recovery of the system [23]. The synergistic effect of electric hydrogen production devices and energy storage devices becomes a new way for wind power stations to respond to system frequency regulation [24]. Reference [25] analyzes the inertia response mechanism of the synchronous generator. The paper proposes to use the power throughput of energy storage devices to enable wind power stations to have inertial response capabilities. However, the primary frequency regulation is not considered. Reference [26] proposed a power fluctuation suppression method based on the active release of wind turbine rotor kinetic energy and an energy storage device, but did not consider grid frequency changes. References [27; 28] establish the mathematical model of the electric hydrogen production device and analyze its operating mechanism. The analysis shows that the electric hydrogen production device can respond to system frequency changes by reducing load. Still, the impact of its dynamic characteristics on the frequency regulation effect is ignored. Reference [29] proposed a power allocation model to coordinate the control strategies of energy storage devices and electric hydrogen production devices. However, the article does not explain the connection between system frequency and power commands. References [30; 31] construct a micro-grid architecture including wind power, energy storage, and controllable load, and a hierarchical collaborative frequency regulation method based on the model prediction algorithm is raised. However, the frequency regulation advantages of each unit and the reasonable distribution of power instructions are not considered. This research examines the main operational mechanism for frequency management in a hybrid plant station in order to address the aforementioned issues. It suggests a variable-parameter ensemble empirical-mode decomposition (EEMD) algorithm-based control technique for primary frequency regulation in a hybrid plant station. 1. A hybrid plant station, which is based on a synchronous generator, combines energy storage, electric hydrogen production, and wind power generation. It participates in the primary frequency regulation characteristic analysis and can support system frequency recovery in the same way as a traditional power station. 2. After establishing a mathematical model of the energy storage device and the electric hydrogen production device, the two were selected based on their respective economies and dynamic properties, as well as their effects on the system. An analysis is conducted on the capabilities of hybrid power plants to regulate frequency. 3. The influence of various EEMD parameters on the power distribution results is analyzed, and a multi-energy cooperative frequency regulation control strategy based on a variable parameter control EEMD algorithm is raised. This is all based on the EEMD algorithm to achieve a rational distribution of frequency regulation power. The main frequency regulation simulation model for a hybrid power station under varying wind speeds is developed, and the simulation's outcomes confirm that the suggested control strategy is effective.
