摘要：
The increasing wind power penetration reduces the inertia and relative reserve capacity of the smart grid, which brings challenges to load frequency control. In power system frequency regulation, the participation of wind turbine provides a new way to solve this challenge. Firstly, based on the single wind turbine model, an inertial control method is proposed for fast kinetic energy extraction, and its complementarity with the pitch angle control is discussed. Maximum of the inertial adjustment provide support for reducing the burden of the pitch angle regulation. Secondly, on the basis of calculating the active power shortage of the power system and analyzing the boundary of the frequency regulation capability of wind turbine, a conditional driving strategy for the wind turbine pitch angle to participate in the frequency regulation is proposed, aiming at reducing the participation of the wind turbine pitch angle in the frequency regulation, and further reducing the strokes of the wind turbine participation. The simulation results show that the designed control method can maximally reduce the times and amplitudes of the pitch angle adjustment, and improve the grid frequency control effectively. © 2020, Power System Technology Press.
