This invention provides a method, system, equipment, and medium for frequency regulation optimization control of a wind-storage combined power station. During primary frequency regulation, the system releases rotor kinetic energy through virtual inertial control of the wind turbine to dampen frequency drops during the inertial response phase. Energy storage compensates for the later-stage power output decline of the wind turbine and avoids secondary frequency drops caused by the wind turbine, effectively improving the frequency response characteristics of the system during primary frequency regulation.

When the actual rotating direction of the rear wheel is inconsistent with the target rotating direction, namely, the rear wheel is running towards the target position by overcoming the inertia control of the actuator, whether a safety risk exists or not is judged according to a deviation value between the actual rotating angle of the rear wheel and the target rotating angle represented by the target steering instruction and a first deviation threshold value; the first deviation threshold value is greater than the second deviation threshold value. The judgment threshold value of the rear wheel steering controller is properly prolonged, and the situation that the front impulse generated by an actuator exceeds the preset monitoring threshold value due to rapid reversing operation, and consequently the rear wheel steering controller enters a safe state unexpectedly is avoided.
