NERC Recommends Approaches for Underfrequency Load Shedding Programs
février 24, 2022In a recently released reliability guideline, NERC recommends additional approaches for Underfrequency Load Shedding (UFLS) program design to help utilities effectively consider the effects of Distributed Energy Resources (DERs). The guidance was developed to address the accelerated transition of the power system to locally installed, decarbonized resources that depend on inverters. These new technologies introduce operational controls issues into the electric grid. UFLS data gathering and analysis methodologies may require modification to address reliability risks.
