Abstract
A useful method for system frequency adjustment of wind turbines is theoretical inertia control. The classic PD theoretical inertia control has difficulty in parameter setting, and does not provide useful inertial support for the system on a case-by-case basis. Therefore, a theoretical inertia control way for wind turbines on account of Model Predictive Control (MPC) is proposed, which provides inertia support when frequency events occur. To confirm the availability of the proposed control method, MATLAB/Simulink® software was employed for system modeling and simulation. The simulation consequences demonstrate that when the system is disturbed by the load, the proposed MPC theoretical inertia control has better robustness and frequency stability than PD theoretical inertia control.
