Guest Editorial: Special issue on real-time simulation and validation of modular multilevel converter-based high-voltage direct current systems

Abstract

Modular multilevel converter-based high-voltage direct current (MMC-HVDC) technology is advancing rapidly in modern power systems, striving for higher voltage levels and greater power transmission capacity. Real-time simulation has become an essential tool for the design, analysis, and validation of MMC-HVDC systems. However, the complexity of MMC-HVDC with its numerous fast-switching power electronic components presents significant challenges in accurately capturing dynamic responses. Advanced simulation techniques are indispensable for modelling the intricate behaviours of converters, control systems, and protection mechanisms, which are critical for the reliable operation of MMC-HVDC systems.

We are honoured to have been invited by High Voltage to serve as guest editors for this special issue, which highlights key achievements in the field of real-time simulation and validation of MMC-HVDC systems. This issue comprises both invited and submitted papers. After rigorous peer review, four outstanding articles were selected showcasing cutting-edge research in real-time simulation technologies, advanced computational methods, and innovative platforms for emerging new power systems.

We extend our heartfelt gratitude to all contributing authors for their exceptional work and to the reviewers for their meticulous and insightful feedback, which have been instrumental in ensuring the quality of this special issue. We also sincerely thank the editorial team of High Voltage for their support and dedication throughout the preparation process.

We hope this special issue serves as an inspiring and educational resource, offering valuable insights and advancing the field of MMC-HVDC systems. Happy reading!
