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 ...

A Coordinating Control for Hybrid HVdc Systems in Weak Grid
IEEE Transactions on Industrial Electronics, 2019 A coordinating control strategy is proposed for a hybrid high voltage dc (HVdc) system comprising a capacitor commutated converter connected in series with a two-stage voltage source converter called “Vernier.” This approach ensures that 1) the tap changers and switched capacitor banks are eliminated by Vernier controls that maintain constant firing ...
