Since multilevel converters provide the combination of outstanding harmonic performance and low switching frequencies, they are a potential option in Small-Scale DC Power Network. With the addition of redundant sub modules in the cascaded converter chain, dependability may be further increased. Next-generation small-scale electric power networks, DC microgrids have extremely low line impedance and have been on the rise.This phenomenon creates significant currents in the micro grids with even a little change in voltage, making quick transient response and accurate power flow regulation essential for a power flow controller. In order to achieve fast and precise power flow regulation in a dc micro grid, this research employs multi-level converters as the controllers. Because of the use of a multi-level converter, the output filter may be made rather compact. The current ripple requirement is met by the design of an LC filter at the multi-level converter's output, which is shown in this project. By comparing the performance of a multi-level converter with that of a traditional two-level converter, we find that the latter is unable to manage the flow of power via low-impedance lines at fast speed and with the same degree of accuracy. Step response analysis utilising MATLAB/Simulink simulation results assesses the control performance of each output current in light of transient changes in the power flow.
