摘要: This study presents a backstepping power control (BPC) design for the grid-side voltage source converter (GSVSC) in converter-based high-voltage dc (VSC-HVDC) wind generation system. First, dynamic model by taking parameter variations and external disturbances into account is derived on basis of space-vector theory to achieve decoupling characteristic GSVSC VSC-HVDC. Moreover, based procedure, BPC scheme developed sense Lyapunov stability theorem satisfy multiple objectives stable HVDC bus grid connection with unity factor. The salient feature proposed introduction additional error terms laws reduce chattering phenomena traditional control. In addition, effectiveness demonstrated numerical simulations doubly-fed induction generator farm VSC-HVDC connection, its advantage indicated comparison proportional-integral strategy under wide range operating conditions possible occurrence uncertainties.
