Various Frequency Control Methods for Wind Turbines: Theory and Simulation

Abstract

When wind power generation increases, traditional power plants replace previous power sources. Currently, frequency control is mainly supported by governors. However, for high ratio of wind power, wind turbines must have the capability to provide frequency controls. In recent years, different frequency regulation methods for wind turbines have been developed. This study summarizes and compares the control theories of these methods to implement power system simulations. Based on the simulation results, an important reference for designs of wind turbine control is provided by investigating the advantages and disadvantages of various frequency control methods.
