为了使得柔性直流输电MMC-HVDC更加稳定地接入电网,并且有效地抑制其桥臂环流,提出了一种改进型的控制策略.首先,实时监测上、下桥臂电流以及子模块电容电压;通过计算得到环流抑制分量以及子模块电容电压平衡分量,将两者叠加到MMC的调制波中,从而有效地抑制桥臂二次环流分量,同时也降低了系统的开关损耗.然后,利用并网控制策略,独立地控制系统的整流侧和逆变侧的电力潮流,保证直流母线电压在负荷改变时保持恒定,实现了子模块电容电压的动态平衡.最后,搭建MMC-HVDC系统的仿真模型,仿真结果表明,桥臂环流被有效地抑

Abstract ——This article deals with a phase-locked loop (PLL)- based novel control for wind turbine driven doubly fed induction generator interfaced to utility grid with a battery energy storage (BES) connected at the dc link. The control of grid-side converter (GSC) is modified to export/import constant power to/from the grid. The state of charge of BES helps in deciding the reference export power to the grid apart from the manual selection using averaged wind power in a particular period of time. An off maximum power point tracking logic is incorporated in the rotor-side converter (RSC) control to operate the BES within its constraints and, moreover, to feed constant power to the grid. In addition, the energy management scheme of the system is presented in the form of flowchart for both exporting and importing power to/from the grid. The RSC and GSC have taken care of unity power factor operation at stator terminals and to mitigate harmonics and grid currents balancing, respectively. The system performance is found robust as the PLL response is not affected even under grid voltages with dc offset. The system is modeled and simulations are carried out in MATLAB using SimPowerSystems tool box. Moreover, the control scheme performance is compared with conventional control algorithms both in terms of PLL and converter controls. To validate the effectiveness of the control scheme, a prototype of the system is developed. Test results demonstrate the satisfactory performance of the system under various operating conditions.
