With the introduction of advancements in industrialization, the need for electricity generation with stable voltage and current generation. The High Voltage Direct Current i.e. HVDC is a system that is implemented in power grids to enhance the power generation capacity of the system but the HVDC system suffers from the issue of commutation failure. During commutation failure, the voltage of the power system goes down and current increases. Therefore, in this work, the HVDC system with hybrid converters is developed. For the purpose of hybridization, the CCC and LCC converter is used. The simulation is done by introducing the AC and DC fault on inverter and converter both. The results prove that the proposed fault mitigation system performs efficiently to reduce the fluctuations in voltage and current of the power system.
