A Coordinating Control for Hybrid HVdc Systems in Weak Grid
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 ...
