DOI: 10.1109/tsg.2018.2871085
Abstract: Renewable energy sources (RESs) have been extensively employed to replace fossil fuels for reducing carbon footprints. Since RESs are normally coupled to the power grid by fast-response power converters without providing any inertia, the power… read more here.
