86. Optimum Operation of Wind Turbine Energy Conversion System on Effect of Loss Modelling on the Permanent Magnet Generators

Permanent magnet synchronous generator (PMSG) wind energy converters system (WECS) with variable speed operation is being used more frequently in the wind turbine application. Variable speed systems have several advantages over the traditional method of operating wind turbines, such as the reduction of mechanical stress and increase in energy capture. To fully exploit the last mentioned advantage; this paper proposes a simple new sensor-less maximum power point tracking (MPPT) control scheme far PMSG WECS and show the optimum operating points of the PMSG for true maximum output power is not necessarily operating at maximum power coefficient (Cp) value. This is to propose a controller with minimal losses as well as optimum power extraction.
