The paper begins by detailing the electrical wiring and structural configuration of the regional grid. It then performs a thorough evaluation of traditional fault current suppression techniques during a single-phase-to-ground fault in transmission lines powered solely by renewable energy. To improve low voltage ride-through capabilities, the study introduces an advanced strategy that employs an adaptive control of positive and negative sequence components, combined with DC bus voltage stabilization. The efficacy of this approach is substantiated through hardware-in-the-loop simulations and empirical field testing. Results show a substantial reduction in the regional grid's negative sequence component and harmonic content by 18.5% and 81.7%, respectively. Moreover, the DC voltage oscillation is effectively suppressed following the initiation and clearance of a single-phase-to-ground fault. a variable inverter-dominated renewable energy power system back-to-back MMC-based VSCs fault ride-through strategy adaptive positive and negative sequence composite control Full Text Additional Declarations No competing interests reported.
