Fluctuations Mitigation of Variable Speed Wind Turbine through Optimized Centralized Controller
Abstract: A wind energy
conversion system (WECS) including a variable wind turbine in grid-connected
mode is considered to control. In this paper, each component of WECS model is
systematically presented and then the integrated overall model is
validated.Regarding to nonlinear nature of WECS and the complex system
structure as multiple-input multiple-output (MIMO), it is difficult to find a
proper control strategy. To simplify the control design, a centralized
controller, which is compatible with systematic modelling, is employed. In
addition, to enhance the centralized controller performance, an optimization
based on genetic algorithm (GA) is accomplished. Simulation results demonstate
the effectivesness of the proposed control startegy to mitigation fluctuations.
