With the ever-increasing permeation of wind energy into electrical grids, the low operating efficiency and poor stability seem to become major challenges for the power industry because of the stochastic characteristic of wind speeds. Aiming at these problems, this article designs a novel hybrid control method for a permanent magnet synchronous generator–based wind energy conversion system. A port-controlled Hamiltonian with dissipation model is proposed to apply in the models of the machine and grid-side converters of the permanent magnet synchronous generator–based wind energy conversion system. Then, this port-controlled Hamiltonian with dissipation model is used to the energy shaping method of interconnection and damping assignment. The hybrid control strategy, containing the outer-loop proportional–integral control and inner-loop passivity-based control, is finally designed in this article. To achieve the analysis, a Simulink model of the 1.5 MW permanent magnet synchronous generator–based wind energy conversion system is established under various types of wind speeds. A comparative analysis between the proposed hybrid control strategy and conventional proportional–integral vector control is conducted through the electrical behaviors and the harmonic distortion rates. The simulation results verify that the hybrid control strategy has better regulation performance than that of conventional proportional–integral control strategy in terms of maintaining at optimal state and improving system stability. It is also demonstrated that the proposed control strategy optimizes the quality of supplied power, which is of significance to reduce the harmonic pollution of wind energy.

随着风能不断渗透到电网中，由于风速的随机特性，低运行效率和较差的稳定性似乎已成为电力行业的主要挑战。针对这些问题，本文设计了一种基于永磁同步发电机的风能转换系统的新型混合控制方法。提出了一种具有耗散模型的端口控制哈密顿量模型，以应用于基于永磁同步发电机的风能转换系统的电机和电网侧变流器的模型中。然后，将该端口控制的哈密顿耗散模型用于互连和阻尼分配的能量整形方法。混合控制策略 本文最终设计了包含外环比例-积分控制和内环基于无源性的控制。为了实现分析，在各种风速下建立了基于1.5 MW永磁同步发电机的风能转换系统的Simulink模型。通过电气行为和谐波畸变率，对提出的混合控制策略与常规比例-积分矢量控制进行了比较分析。仿真结果验证了混合控制策略在保持最佳状态和改善系统稳定性方面比常规比例-积分控制策略具有更好的调节性能。还证明了所提出的控制策略可优化供电质量，
