In this paper, we present a computationally inexpensive model to calculate wind turbine blade fatigue caused by waking and partial waking. The model accounts for steady state on the blade, as well as wind turbulence. The model is fast enough to be used in wind farm layout optimization, which has not been possible with more expensive fatigue models in the past. The methods introduced in this paper will allow for farms with increased energy production that maintain turbine structural reliability.

The Savonius and H-Darrieus stacked blade can be operated at a wind speed of 1.90 m/s and torque of 1.31 N-m under no-load. We demonstrated that a PMSG electrical generator is able to generate a high starting torque; which is not typical of low speed wind turbines. Using the PMSG with a skewing angle magnet-coil of 15–0 degrees in combination with the blade, the cut-in was found to be at 2.1 m/s in a fully operational vertical wind turbine.
