Frequency modulation, the process of adjusting the power frequency to maintain grid stability, is essential for preventing blackouts and ensuring consistent electricity supply. The grid operates at a nominal frequency, usually at 50 or 60 Hz, depending on the region. This service is crucial in the early moments of a disturbance—before traditional generators can ramp up. For example, if frequency drops below a threshold. . recovery through primary frequency modulation alone. Given this headac ch can fully meet the assessment requirements of AG.
