Integrated control strategy of multibrid wind power generation system

Multibrid wind power generation system (MWPGS) has aroused more and more attention for its high energy conversion efficiency, high reliability, and flexible grid-connected power control. In order to achieve the coordinated control of MWPGS during the operation of various, an integrated control strategy is developed, which incorporates pitch control, the improved hill-climb searching (HCS) control with a fuzzy logic controller (FLC) and PMSG speed control, grid-side voltage orientation control (VOC), and the control of braking resistor based on power balance method. Simulation of control performance for MWPGS is carried out in Matlab/Simulink, and the results verify the correctness and feasibility of the integrated control strategy proposed in this paper.
