In this proposed PI balancing method, the sub-module capacitor voltage of modular multilevel converter (MMC) is applied to one of the applications, HVDC power transmission i.e. MMC-VSC-HVDC. The proposed PI control strategy provides a useful and economical way to transmit electrical power over a long distance. MMC-based VSC-HVDC has lesser power losses, excellent harmonic performance without the need for any filter or PWM technique and carries continuous current in all converter valves. The dynamic performance and stability of the MMC-based VSC-HVDC transmission system increased by using the FUZZY logic controller technique. Both the control techniques of the HVDC transmission system are simulated by using the MATLAB SIMULINK software.
