Collaborative Control Strategy of Wind Farms for Frequency Support Considering the Frequency Distribution Characteristic

Year: 2026

Type: article

Abstract: The lack of power system inertia caused by the large-scale integration of renewable energy seriously threatens frequency stability. In this paper, a control strategy for collaborating multiple wind farms in frequency support considering the frequency distribution characteristic is presented. Firstly, the DC power flow analysis model of the power system is established, the analytical relation between the node frequency and the active power disturbance is derived, and the system frequency distribution characteristic is mathematically analyzed. Secondly, based on the frequency distribution characteristic, a control strategy for collaborating multiple wind farms using virtual inertia control and droop control to provide frequency support is presented. Finally, the four-machine two-area system integrated with two wind farms is implemented in Matlab 2020, and the effectiveness of the proposed collaborative control strategy for frequency support is validated through simulation results.
