一种针对LCL滤波中压并网变流器的预测参考模型预测直接电流控制策略

In this paper, a new model predictive direct current control (MPDCC) strategy is proposed for a medium-voltage (MV) neutral-point-clamped converter with an LCL-filter-based connection to the grid. The proposed strategy addresses the issues of resonance damping and harmonic attenuation through the virtual resistor (VR) concept, and is thus, termed MPDCC-VR. Because MPDCC is capable of achieving ver...
