A sensorless control method for maximum power point tracking of wind turbine generators

Wind energy has been regarded as an environmentally friendly, logistically feasible and economically responsible alternative energy resource. In order to produce as much power as possible in variable speed wind turbine generators, the maximum power point tracking (MPPT) becomes a hotspot of research in this field. In this paper, a simple control method for maximum power point tracking (MPPT) in a variable speed wind turbine by using a boost converter without mechanical sensors is proposed. A climbing algorithm is used to achieve MPPT. Simulation and experimental results are presented to validate the proposed technique.
