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.

As the penetration of wind energy is being dramatically increased, the impact of wind energy on the power system should be roundly studied, especially for the fault characteristics analysis and applicability analysis of low voltage ride-through (LVRT) requirements for a whole wind farm (WF) and an individual wind turbine generator (WTG). This paper firstly describes a detailed modeling of a permanent magnet synchronous generator (PMSG)-based WF and analyzes the fault characteristics of the WF under various fault conditions. The validation of the fault characteristics analysis is carried out with the EMTP-RV generated data, with the consideration of different fault positions, fault types, and wind speeds. The relay protection and the related grid code are also taken into account. In addition, the applicability analysis of LVRT requirements for a WF and a WTG is also implemented, from the points of minimal grid-connection time and minimal dynamic reactive current support ability. The fault characteristic analysis of a PMSG-based WF could be helpful for developing new control or protection methods for a PMSG-based WF. Meanwhile, the applicability analysis of LVRT requirements could serve as a reference for WTG manufacturers, WF administrators, and grid operator.
