Enhancing Resilience and Efficiency in Low‐Voltage Resistive AC Microgrids Through Distributed Control Strategies

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
A distributed secondary control strategy for low‐voltage resistive AC microgrids is proposed, where consensus‐based algorithms dynamically adjust both the slope and offset of V‐I droop characteristics. This dual adaptation enables accurate proportional power sharing and effective voltage regulation at the PCC, while ensuring fast transient response and

Multi‐Layer MTDC Protection: Design and Simulation Assessment

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a novel multi‐layer protection architecture for multi‐terminal DC systems that separates fault current‐limiting and interruption functions. By combining a thyristor‐based fault current limiter with an active resonance circuit breaker, the scheme significantly reduces peak fault currents and di/dt stress, enabling a more compact ...
