摘要

Abstract

With offshore becoming the main battlefield of wind power generation

modular multilevel converter-based high-voltage DC (MMC-HVDC) transmission technology has become an ideal solution for offshore wind power integration and received rapid development. However

wideband oscillation events have seriously threatened stable operation of power systems. By far

existing oscillation mitigation methods are usually designed for specific oscillation cases and are not capable of mitigating wideband oscillations. In order to mitigate various oscillations adaptively

this article proposes an adaptive wideband oscillation mitigation control for MMC-HVDC system connected to offshore wind farms. Analytical wideband impedance models of the wind farm side MMC (WFMMC) and offshore wind farm composed of permanent-magnetic synchronous generator-based wind turbine generators (PMSG-WTGs) are derived

respectively

which are verified by measured impedances from time-domain simulations. Then

a wideband oscillation mechanism is revealed by impedance-frequency characteristics. On this basis

an adaptive wide band oscillation mitigation control is proposed

and its working principle as well as implementation process are elaborated. Case studies of a sub-/super-synchronous oscillation (SSO) event and a high-frequency oscillation (HFO) event of an offshore wind farm with MMC-HVDC system are carried out to verify effectiveness of the proposed adaptive wideband oscillation mitigation control.
