Abstract

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.
