Power control for a small-sized stall-regulated variable-speed wind turbine using power loop and speed loop control method

This paper focuses on power optimization for a small-sized stall-regulated variable-speed (SS-SR-VS) wind turbine system. In this paper, the behavior of the SS-SR-VS wind turbine during power optimization is demonstrated. The Speed Loop Control method with the assistance of classical Proportional Integral (PI) controller is used. Controller parameter is designed based on the linearization process, and the pole-placement procedure has been applied during the controller tuning. Further improvement is then done by using the Good Gain method. The comparison between these two methods is presented. Results show that the turbine speed, generator speed and hence the generated power can be optimized at the optimum values corresponding to the wind speed variations during power optimization
