Resumen:

This paper presents a methodology to design under-frequency load shedding (UFLS) schemes in power systems, which is supported by transient studies of critical contingencies related to load/generation imbalances that deplete the system primary reserve. The load shedding and frequency set points of each stage related to the UFLS scheme are determined based on the power system inertial and primary frequency responses. The present methodology can be applied to power grids with both conventional and intermittent renewable generation power plants. To showcase the usefulness of the developed UFLS scheme, this was implemented in PSS/E Explore v35 and applied to the 39-bus New England test system including two renewable power plants. © 2023 IEEE.
