“…This strategy maximizes utilization of the wind turbine rotor's kinetic energy while minimizing the necessary energy storage capacity. The authors of references [6][7][8] investigate various energy storage devices such as SCs, flywheel energy storage systems, lithium batteries, and hydrogen fuel cells to examine their effects on primary frequency regulation. From the perspective of coefficient optimization, various methods such as linear segmentation, S-function, and fuzzy control were employed in [9] to rectify the charging and discharging coefficients.…”

To address the challenge of wind turbines meeting primary frequency regulation requirements, incorporating energy storage devices to handle most of the frequency regulation tasks would result in increased operational costs. When a wind turbine rotor accelerates, it deviates from the maximum power tracking point (MPPT), leading to reduced output while retaining significant rotational kinetic energy. Based on this characteristic, a primary frequency regulation strategy is proposed that coordinates the rotor kinetic energy of a double-fed induction generator (DFIG) with supercapacitors (SCs). Supercapacitors provide power support during low-frequency conditions, while accelerating the wind turbine rotor reduces output during high-frequency conditions. Additionally, continuous attention is given to subsequent frequency changes. In case of short-term, low-frequency conditions, stored kinetic energy is released for power support, establishing a mechanism for wind turbine kinetic energy recovery and release. This mechanism reduces charging and discharging requirements for supercapacitors, extends their service life, and considers both wind turbine frequency regulation requirements and economy. Finally, using MATLAB 2020/Simulink platform allows for the verification of the effectiveness and rationality of this proposed method.
