DOI: 10.1109/access.2024.3510415
Abstract: The implementation of low-voltage-ride-through (LVRT) requirements for distributed generation (DG) sources in medium voltage (MV) distribution networks introduce challenges for the existing protection systems. These challenges stem from coordination issues between line protection systems (fuses… read more here.
