Abstract: Frequency disturbances in the power grid frequently occur in wind power generation. To address the issue that doubly fed motors cannot effectively respond to grid frequency disturbances, leading to significant output power disturbances, this paper draws on a doubly fed wind turbine model to establish a doubly fed wind turbine frequency response model. The parameters of the speed control loop were optimized using a multi-objective optimization-weighted genetic algorithm. The study demonstrates that this model achieves frequency response while effectively reducing output power overshoot and recovery time, thereby enriching existing research findings on the transient stability of new energy grids.
