模块化多电平变换器能量平衡控制的能量谐波稳定性分析

The energy-balancing control (EBC) plays a crucial role in the proper functioning of the modular multilevel converter (MMC). However, regarding the stability analysis of MMC energy balance, the discussion on internal energy balance is usually ignored, whereas it has been demonstrated in the existing literature that the capacitor energy harmonics may affect the system stability. This article consid...
