Methodology for Identifying Representative Rates of Change of Frequency (ROCOFs) in an Electric Power System against N-1 Contingencies

Engineering Proceedings, 2023
An Electric Power System (EPS) is a dynamic system that, due to continuous variations in the load, the presence of disturbances, switching operations, and/or the operation of the protection system, is never in a steady state.
