Fast Fault-Tolerant Grid Frequency Measurement

open access: yes2025 IEEE Power & Energy Society General Meeting (PESGM)
As power systems adopt greater levels of asynchronous generation, operators increasingly need to accurately monitor and manage their systems. With inverter-based generation progressively displacing traditional synchronous generators, power systems generally experience increased rate of change of grid frequency and wider propagation of voltage ...
