The transmission of bulk power has been facilitated by high-voltage direct-current (HVDC) links. Among the different types of HVDC technology, voltage source converter (VSC) based configurations, particularly modular multilevel converter (MMC) implementations, are highly attractive due to the possibility to interconnect additional terminals to form multi-terminal HVDC systems-offering a greater controllability and system reliability. However, this flexibility comes at the expense of additional challenging requirements in terms of protection and control. This 3.5 year research project will examine these challenges and will provide novel solutions towards facilitating deployment of multiterminal HVDC systems.

高压直流输电线路促进了大容量电力的传输。在不同类型的HVDC技术中，基于电压源换流器（VSC）的配置，特别是模块化多电平换流器（MMC）实现，由于可以互连附加端子以形成多端HVDC系统，从而提供更大的可控性和系统可靠性，因此非常有吸引力。然而，这种灵活性是以保护和控制方面的额外挑战性要求为代价的。这个为期3.5年的研究项目将研究这些挑战，并将为促进多端HVDC系统的部署提供新的解决方案。
