520			_aPartial blade pitch is investigated as a means for wind turbine power regulation after the rated wind speed. Traditionally blades are pitched fully along the span, which is becoming increasingly difficult as the blades are getting longer. Since the power is generated from the outboard section, a partial blade twist of the outboard section is investigated. Two models are used in this study: (1) the BEM model and (2) the CFD technique. The BEM offers speed and versatility and is only used to explore the concept of partial twisting, whereas the CFD can examine effects of flow separation at the blade discontinuities caused by the partial twist. Further, two wind turbines are investigated: (1) the NREL Phase VI and a small lab wind turbine. The NREL VI turbine is examined to compare the model results to published data, whereas the lab model was pursued to test in the lab in future studies. The results found that it is possible to use partial blade twisting for power regulations
