The participation of wind power in grid frequency support is pivotal to maintaining the safe and stable operation of the grid. MATLAB， as common simulation software， can only build small-scale power system models containing wind power， and the simulation speed is low. To carry out wind power frequency support control research in MATLAB and improve the research efficiency， a fast simulation model based on the simplified model of wind turbine and grid frequency response model is constructed. Then， a method is proposed to obtain the SFR （system frequency response） model excluding the wind power frequency support. Finally， the validity and efficiency of the fast simulation model are verified by the example. The results show that the frequency response of the constructed fast simulation model is consistent with the complete power system model， and the simulation speed of the wind farm can be increased by more than 130 times when a single unit equivalent is used， and by nearly 1，100 times when all units of the wind farm are retained， which significantly improves the efficiency of wind power participation in grid frequency support research under MATLAB software. |
