Modeling and Simulation of Frequency Droop Control for Wind Turbines
Wind power generation technology, as a green power generation method with the deepest research depth and the widest application range, has come a long way in recent years. With the large-scale wind turbine get connected to the system in a large range, some characteristics brought by it will inevitably brought a lot of influence on the frequency regulation of the power system. At present, the most widely used type of wind turbine is doubly-fed induction wind turbine, which uses frequency converter for control. As a result, the wind turbine is completely decoupled from the system frequency, and the rotor kinetic energy of the wind turbine is "hidden", so it is unable to respond to the frequency change of the system. When a large number of wind turbines are connected to the grid, the frequency stability of the grid will be affected. Therefore, it is of great theoretical and practical significance to study the FM control strategy of wind turbine for the safe, stable and economic operation of power grid.
