This paper presents Modular Multi Level Converters (MMC) are used for high voltage high power DC to AC conversion. The MMCs with increased number of levels offer close to sine wave operation with reduced THD on the AC side. This is a new type of voltage source converter (VSC) topology. The use of this converter in a high-voltage direct current (HVDC) system is called by a MMC-HVDC system. The MMC-HVDC has the advantage in terms of scalability, performance, and efficiency over two-and three-level VSC-HVDC. The proposed HVDC system offers the operational flexibility of VSC based systems in terms of active and reactive power control, in addition to improved ac fault ride-through capability and the unique feature of current-limiting capability during dc side faults. The proposed VSC-HVDC system, in this project assesses its dynamic performance during steady-state and network alternations, including its response to AC and DC side faults. In this project using a fuzzy controller and the proposed topology is implemented in MATLAB/SIMULINK environment and the simulation results are observed.
