Given the differences between wind and thermal power in frequency regulation (the former is capable of rapid response while the latter possesses sustainable characteristics)
this paper proposes a primary frequency regulation control strategy
which realizes efficient coordination among the two power sources and the energy storage system. Firstly
tailored to the diverse operational states of wind turbines in wind farms
a power distribution strategy based on a frequency regulation reserve factor is introduced
ensuring their safe and effective participation in frequency regulation. Moreover
a fuzzy control-based strategy for coordinating thermal and storage is designed to recover rotor speed. This strategy facilitates rapid and economical restoration of rotor speed
addressing the issue of secondary frequency drops in the system. Simulation results indicate that this strategy effectively achieves the coordinated primary frequency regulation of wind
thermal and storage systems
while ensuring economic benefit and reliability
which takes full advantage of the frequency regulation capacity of wind power
effectively improving the system's frequency characteristics.
