    Abstract: To address the challenges posed by the large-scale integration of new energy into the grid on the frequency stability of the power system, this paper explores a load-frequency control (LFC) strategy for interconnected regional power grids equipped with energy storage devices.A state space model of a two-area interconnected system incorporating thermal power units is constructed, and the power constraint characteristics of energy storage units as frequency modulation actuators are analyzed. A load-frequency regulation method for regional interconnected power systems based on the hawkfish optimization algorithm (HFOA) is designed. This method ensures asymptotic stability of the system frequency while achieving optimal allocation of frequency modulation output signals from the hybrid energy storage system (HESS). A preset performance controller is employed to quickly converge the area control error within a target range. Simulation experiments are conducted using the MATLAB/Simulink platform, the results show that, compared to the grey wolf optimization algorithm, the proposed strategy can better maintain the stability of the regional interconnected power system and improve the system's frequency modulation performance.
    Key words: regional interconnected power system; load-frequency control; hawkfish optimization algorithm; grey wolf optimization algorithm;hybrid energy storage system ; area control error
