摘要：
With the large-scale development of renewable energy, the wind power has been integrated into the power grid in large quantities and its penetration rate has been increasing. On the one hand, the overall inertia of system is reduced because traditional power generators are replaced by wind turbines that have a smaller inertia time constant. On the other hand, the intermittency and randomness of wind power production affects the system frequency characteristics and further reduces the system frequency regulation ability. The participation of wind power units in frequency regulation is one of the effective means to accommodate the penetration of wind power. Hence, the participation of wind power in the field of frequency regulation is reviewed. Firstly, the frequency regulation control strategies of the two most commonly used wind power unit, i.e., variable-speed wind turbines of doubly-fed induction generator and permanent magnetic synchronous generator, are taken as an example, the principles, advantages and disadvantages, development tendency of the rotor overspeed control, pitch angle control, combined virtual inertia control, virtual synchronous generator control, energy storage and wind power frequency regulation, and the combination of multiple control strategies are reviewed. Subsequently, some key problems of wind farm participating in system frequency regulation are analyzed. Finally, the future research directions in this topic are summarized. © 2021, Electric Power Automation Equipment Press. All right reserved.
