Transmission system protection screening for integration of offshore wind power plants
Renewable Energy, 2018 Abstract This paper develops an efficient methodology for protection screening of large-scale transmission systems as part of the planning studies for the integration of offshore wind power plants into the power grid. This methodology avails to determine whether any upgrades are required to the protection system. The uncertainty is considered in form
