Optimal fractional order control of wind turbine pitch angle by considering probabilistic wind model

In this paper, a new method for optimal design of fractional order controller for controlling the pitch angle of wind turbine is presented. The proposed controller is optimized utilizing a meta-heuristic algorithm, named whale optimization algorithm (WOA). For these purposes, the dynamic modeling of the components involved in the system is initially performed. In this design, we have also incorporated intermittent nature of wind energy, which means stochastic wind model is combined with a conventional diesel generator in the system. Simulation is performed to evaluate the performance of the proposed controller utilizing two different performance criteria. Finally, the comparisons of the proposed model with conventional models have been considered
