摘要/Abstract

摘要： 构网型柔性直流输电系统接入电网,实现对受端电网电压和频率的支撑。针对构网型柔性直流输电系统受端电网引起的振荡问题,提出固定时间滑模控制方法。首先,基于虚拟同步机控制,建立构网型柔性直流输电系统的数学模型。然后,基于滑模控制和固定时间稳定理论,提出非线性固定时间滑模控制方法以抑制系统振荡。通过李雅普诺夫理论证明了所提的非线性固定时间滑模控制能够实现柔性直流输电系统在固定时间内恢复稳定。最后,在MATLAB/Simulink中建立构网型柔性直流输电系统的仿真模型,验证所提方法在振荡抑制方面的有效性和优越性。

Abstract: The grid-forming voltage source converter based high voltage direct current(VSC-HVDC)system is connected to the grid, which supports the voltage and frequency of the grid. This paper focuses on the oscillation problem caused by the receiving end grid of grid-forming VSC-HVDC system and proposes a fixed-time sliding mode control method to damp the oscillation. First, a mathematical model of the grid-forming VSC-HVDC system is established based on virtual synchronous generator control. Then, a nonlinear fixed time sliding mode control method is proposed for oscillation suppression control according to the sliding mode control and fixed time stability theory. Furthermore, Lyapunov theory proves that the proposed nonlinear fixed time sliding mode control can realize the restoration of stability of the grid-forming VSC-HVDC system within the fixed time. Finally, a simulation model of the grid-forming VSC-HVDC system is constituted on MATLAB/Simulink and the simulation results verify the validity and superiority of the proposed method in oscillation suppression.

Key words: grid-forming VSC-HVDC system, virtual synchronous generator control, oscillation suppression, sliding mode control, fixed time stability
