Coordinative optimization on fatigue distribution and active power in wind farms

As fatigue damage being the most important reason and basis of wind turbine maintenance, a novel active power dispatching approach was proposed to optimize the fatigue distribution of wind turbines in large-scale wind farms. In this approach, the relationship of fatigue and active power of a wind turbine was built. The grid demanded active power of a wind farm was dispatched to wind turbines according to the inverse proportion of fatigue of wind turbines. Especially, available power and lower limit power of a wind turbine were considered well over, so as to the reference active power of a wind turbine could be carried out. The results of simulation illustrate that the proposed solution is a feasible way to optimize fatigue distribution in wind farms and trace the grid demanded output of wind farms, which may contribute to lower visit of maintenance in a wind farm thus cutting down the maintenance cost of large-scale wind farms.
