For the converter-interfaced renewable energy systems, due to the inherent intermittent characteristic of renewable energy and the AC fault current limiting of interfaced converters, the conventional overcurrent protection suffers from low reliability. Distance protection can be adopted in light...

Fast and reliable black start plays a key role in improving the ability of the power system to resist the risk of large-scale blackouts. For a black start with high voltage and long-distance transmission lines, it is much easier to cause phenomena such as self-excitation and power...
