虚拟同步发电机技术在风力发电系统中的应用与展望
Application and Prospect of Virtual Synchronous Generator in Wind Power Generation System
摘要
Abstract
With the increasing penetration of wind energy and due to the large-scale utilization of wind turbines,the present power grid is developing into a system with the loss of rotational inertia,thus it brings about various stability problems. However,as the virtual synchronous generator (VSG) technology can mimic the characteristics of the conventional synchronous generator,the equivalent inertia and damping coefficient of wind turbines and the penetration rate of wind energy in the grid are improved.Firstly,the research prospect of VSG technologies which applied in the field of wind turbine control are introduced.Then,the coordinated control of maximum power point tracking(MPPT)and frequency support is discussed, as well as the energy balance between the actual turbine shaft and virtual shaft is revealed.Also,the designs and stability analysis of key parameters of VSG controlled wind turbines are elaborated.The specific applications in wind turbines are illustrated via the simulations on a permanent magnetic synchronous generator(PMSG)-based wind turbine and a doubly-fed induction generator(DFIG)-based wind turbine.Moreover,the feasibility and prospect of the VSG controlled wind turbines in the area of large wind farm aggregation and specific control methods are addressed.Finally,some remaining difficulties and perspective solutions are also demonstrated.关键词
