A Novel Digital Twin Platform for Accelerating Power Systems Restoration

Energy Internet, Volume 3, Issue 2, Page 111-141, July 2026.
Hardware Architecture Design of DT System in Laboratory. ABSTRACT With the global energy structure transforming towards the goal of net zero emissions, the penetration of an inverter‐based resource (IBR) in power systems is increasing. This transformation poses two critical challenges: the system post blackout restoration process becomes extremely ...

Single Pole-to-Ground Fault Analysis of MMC-HVDC Transmission Lines Based on Capacitive Fuzzy Identification Algorithm

Energies, 2020
The probability of a single pole-to-ground fault in high voltage direct current (HVDC) transmission lines is relatively high. For the modular multilevel converter HVDC (MMC-HVDC) systems, when a single pole-to-ground fault occurs, the fault current is ...

Towards Power Import and Regional Grid Interconnection: A Singapore‐Centric Energy Internet

Energy Internet, Volume 3, Issue 2, Page 86-91, July 2026.
ABSTRACT Singapore is accelerating its energy transition by pursuing large‐scale cross‐border renewable power import and regional grid interconnection. Targeting up to 6 GW of low‐carbon power import by 2035—equivalent to nearly half of its projected electricity demand—Singapore is poised to transform from a gas‐dominated urban power system into a ...

Attractive Space Evaluation Method for HVDC Transmission Lines

Energies
High-voltage direct current (HVDC) transmission lines are increasing in number and overall length. This means their lightning protection must be of higher importance as well. Probability-modulated attractive space (PMAS) theory is a proven geometry-based method for lightning protection calculations.
