Research on the FM control for hydraulic wind turbine based on virtual inertia compensation control method
Wind has been admitted as one of the most promising renewable energy resources in multinational regionalization policies. However, the intermittent wind energy volatility and the weak coupling between traditional wind generators and the power grid all influence the electrical grid frequency stability. The hydrostatic transmission wind turbine (HWT) is taken as the research object, and the hydraulic energy storage system (HESS) is introduced into HWT to improve the frequency regulation capability. First, the mathematical models of rotor, hydraulic power main transmission system, and the excitation synchronous generator are established. Then, the HWT frequency modulation characteristics are analyzed under different amplitude of load frequency fluctuation. In view of the HWT limited frequency modulation capability, the frequency modulation control strategy based on virtual inertia compensation is proposed with the HESS. Under the condition of maximum power point tracking, the effectiveness is verified. The simulation and experimental results show that the control strategy has a good control effect, and the HESS dynamic response characteristic satisfies the wind power–frequency regulation. The research results will be helpful to make wind power become grid-friendly power and solve the problem of electrical grid low frequency stability.
