Abstract

This invention discloses a three-objective parameter optimization method for VSG-type wind turbines that considers both dynamic and steady-state performance. The method includes: establishing a mathematical model of the VSG-type direct-drive wind turbine and linearizing the turbine's operation process to obtain a linearized model reflecting the relationship between control parameters and the turbine's steady-state power characteristics and dynamic oscillation characteristics; based on the linearized model, constructing a multi-objective parameter optimization model to characterize the turbine's steady-state performance, dynamic performance, and system operating characteristics; solving the multi-objective parameter optimization model while satisfying the constraints on control parameter values ​​to determine the control parameter configuration scheme for the VSG-type direct-drive wind turbine, and applying the control parameters to the turbine control process. This invention enables the synergistic optimization of the wind turbine's steady-state power control performance and dynamic oscillation stability performance within a unified framework.
