Reduced-Order-VSM-Based Frequency Controller for Wind Turbines

Reduced-Order-VSM-Based Frequency Controller for Wind Turbines

Frequency support capability is becoming an important requirement for wind turbines, as wind power is increasingly integrated into power systems. In this paper, a frequency controller is implemented and validated. Such a controller allows wind turbines to help regulate the system frequency automatic...
