Method to enable variable speed wind turbine primary regulation

This article proposes a method to enable variable speed wind turbine primary regulation. The method consists of adjusting the power-speed curve of the turbine to the grid frequency, thus varying the percentage of maximum power available injected to the grid. This is achieved by operating at rotational speed different from the optimal, and not controlling the pitch angle. Two practical implementations of the method are proposed and demonstrated by simulation exercises.
