摘要

为了克服基于“dqo”的控制问题,将基于互连和阻尼分配的无源控制(IDAPBC)与相位无关地应用于模块化多电平变换器(MMC)。此外,还提出了一个平衡点估计器来确定非线性控制器输入所需的MMC的时变平衡状态。该控制策略提供了MMC对其交流和直流侧变化的全局鲁棒稳定性。控制+估计器策略结合了MMC的状态空间模型和能量动力学模型。

Energy concept-based nonlinear stabilization and control for Modular Multilevel Converters for voltage oscillation reduction
The Interconnection and Damping Assignment Passivity-Based Control (IDAPBC) is applied phase-independently to the Modular Multilevel Converter (MMC) in order to overcome “dqo”-based control problems. In addition, an equilibrium point estimator is proposed to determine the time-varying equilibrium state of the MMC needed as input for the non-linear controller. This control strategy provides global robust stabilization of the MMC against variations on both its AC and DC sides. The control + estimator strategy combines both the state-space and energy dynamics models of the MMC.
