| Summary: | Smoothing output power fluctuations of wind power generation systems is crucial for the stable operation of power grid. Based on the port-controlled Hamiltonian （PCH） model， an integrated control strategy for rotor speed tracking and power smoothing in directly-driven permanent magnet synchronous generator （D-PMSG） wind power generation systems is studied. To address the issue of low wind energy capture efficiency during power smoothing， a control strategy that integrates rotor speed smoothing control and PCH-based passive control is proposed. The strategy enables the rotor speed of the PMSG to quickly track the reference speed， improving wind energy capture efficiency while achieving DC link voltage control. Within the rated operating range of wind turbines， the strategy provides effective power smoothing support. Simulation results comparing this strategy with MPPT and other smoothing control strategies demonstrate the effectiveness and superiority of the proposed power smoothing strategy. |
