Theoretical and simulation-based insights into the dynamic behavior and performance metrics of proposed model to provide critical assessments and strategies to address challenges associated with MMC-HVDC systems. Ultimately, this comprehensive study fosters the broader integration of MMC-HVDC technology into smart grid infrastructures.
MMCs are indispensable for HVDC power transmission and grid connections . The proliferation of HVDC transmission systems has been dramatically revolutionized by the utilization of MMC, resulting in a notable rise in the implementation of HVDC projects worldwide .
The breakeven range for determining whether HVDC is economically viable in the context of overhead lines is generally estimated to be from 500 to 900 km as depicted in Fig. 6. HVDC systems begin to exhibit cost-effectiveness beyond this threshold through the mitigation of losses that are common in long-distance AC transmission.
Cybersecurity Threats Detection for HVDC-MMC: As the integration of digital technologies in HVDC systems increases, so do the cybersecurity risks. This research does not address the potential cybersecurity threats associated with MMC-HVDC systems, which is a growing concern in the context of modern energy infrastructures.
As MMC-based HVDC grids encounter challenges from rapid fault currents, investigating fault detection and establishing robust mitigation strategies would significantly enhance the resilience and reliability of MMC-HVDC systems.
Regarding the configurations of HVDC converters, they primarily fall into two categories: the Current source converter (CSC) and the Voltage Source Converters (VSC). The converter for the current supply, also recognized as the Line-commutated converter (LCC), utilizes the transmission voltage for commutation.
