Multi-Terminal HVDC Implementation for Connecting Indonesian Islands: Technological Review

Multi-terminal high voltage direct current (MTDC) systems have emerged as a modern technology for the integration of renewable energy sources and the enhancement of power system stability and reliability. The development of the MTDC system continues to produce a more efficient and reliable system. This development of MTDC systems includes the system configuration, converter topology, control strategy. Each of those development offers its own benefits in optimizing the MTDC system. This system is suitable for countries that have renewable energy potential in meeting the needs of well-distributed electrical energy and making the energy transition, such as Indonesia. Indonesia has a huge amount of renewable energy potential that needs to be utilized optimally. This paper provides a comprehensive overview of converters and control strategies in MTDC systems. The advantages and disadvantages of each converter and control strategy are presented as a reference in designing the MTDC system.
