TSO experience with voltage control from wind power plants
Modern wind power plants (WPPs) are equipped with sophisticated controllers that allow various schemes to be used by manufacturers to meet grid code requirements. This includes active and reactive power controls as well as voltage control. Voltage control can be achieved in a number of different ways to satisfy the different grid codes, but also the project specific needs. Hydro-Québec TransÉnergie (HQT) has performed numerous dynamic studies related to the integration of WPPs and optimisation of their control schemes including voltage control. This study presents the HQT experience with various voltage control issues including tuning of the WPP controller and study cases of angle and voltage stability issues.
