Modular multilevel converters (MMCs) are susceptible to subsynchronous oscillations (SSOs) caused by impedance interactions in the power line. Current research into the stability of MMCs focuses mainly on voltage feed-forward control, while the effec

Abstract LCL grid‐connected inverter is good at suppressing the high frequency current, but the inherent resonance frequency of the filter will lead to the resonance peak. Therefore, the active damping is commonly used to suppress the resonance eff

Conventional finite-control-set model predictive control (FCS-MPC) and low-complexity MPC (LC-MPC) may cause variable switching frequency and high sampling frequency. To address these concerns, a new LC-MPC scheme with a constant switching frequency
