Modular Multi Converter for DC Fault Protection based Levy Multi-Objective Gray Wolf Optimization

The main aim in this research provides a definition of the Modular Multi-Level Converter, a novel converter network topology created for HVDC applications, as well as details on how it operates and the outcomes of simulations. This study offers a more effective levy based multi objective grey wolf optimization technique to effectively address the DC failure problem. A grid device recovers the quality of the power in systems that are connected to the grid. It is a hybrid of a two-level converter and a modular multilevel converter; each arm has H-bridge cells. As a result, the MMC can operate in a sweet zone where AC and DC energy flow in the same direction. Because the executive switches in the MMC alternate the length of conduction for each arm, fewer cells are stacked. The MMC can support the ac grid and continue to control the current in the phase reactor. The loss estimation and simulation results in this study are in line with the characteristics of the MMC.
