Research on MMC Reverse Model Predictive Control Strategy
模块化多电平换流器MMC(modular multilevel converter)的模型预测控制存在权重因子难以精确设计和计算负荷大等问题,针对这些问题,提出一种MMC逆向模型预测控制策略.通过逆向预测交流侧相电压和每相上、下桥臂总电压,并利用取整函数和目标函数寻优,计算上、下桥臂投入子模块数,独立控制交流侧电流和桥臂环流.所提方法在无需设计权重因子,且每个采样周期只需进行2次循环寻优的同时,还可使交流侧最大输出2N+1电平,并有效控制桥臂环流…查看全部>>
In the model predictive control ( MPC ) of modular multilevel converters ( MMCs ),it is difficult to accurately design the weight factor,and the amount of computational load is usually large.To solve these problems,an MMC reverse MPC strategy is proposed.The AC-side phase voltage and the total voltage of upper and lower bridge arms of each phase are predicted by reverse prediction,the number of input sub-modules of upper and lower bridge arms is …查看全部>>
