Abstract
Modular multilevel converter (MMC) plays a significant part in high voltage power electronic industries due to its wide range of benefits such as modularity and reliability. The circulating component exists between three-phase half-bridge MMC causing certain issues in the design of MMC such as system loss, voltage instability, current disturbance, etc. To handle such problematical factors, a novel circulating current control mechanism named ‘hybrid ebola gannet based generalized type 2 fuzzy controller (HEG-GT2FC)’ is proposed in this paper. Here, the main controlling parameters of MMC namely harmonic distortion, current ripple, and circulating current settling time are adjusted or minimized using the generalized type 2 fuzzy controller. The hybrid ebola gannet algorithm solves the high voltage conversion problem by determining the optimal solution. The proposed HEG-GT2FC mechanism is evaluated using the MATLAB/Simulink tool. The performance of the proposed HEG-GT2FC mechanism is investigated in terms of measures such as current ripple, total harmonic distortion, and circulating current settling time. The simulation results illustrate that the proposed HEG-GT2FC mechanism achieves a very low percentage of current ripple (0.09%), total harmonic distortion (4.98%), and circulating current settling time (0.8 sec) than other compared state of art techniques.
