Parameter identification of wind turbine for maximum power point tracking control

Abstract

Wind energy is a significant and powerful resource. It is safe, clean, and abundant. Variable speed power generation for a wind turbine is attractive, because maximum efficiency can be achieved at all wind velocities. However, this system requires parameters of wind turbine for calculation of the optimum wind turbine operation speed. In this paper, a technique is proposed for maximum power point tracking control of a wind generation system. The optimum operation speed to which the maximization of the output power of the wind turbine is determined takes into consideration identification of parameters by an iterative least squares technique. The effectiveness of maximum power point tracking control with the identified parameters is verified by simulations for the wind power generation system. Additionally, the paper addresses the effect on the rotational speed and output power in the event that the wind turbine parameters used in optimum rotational speed determination have error.
