Frequency regulation in power system In power systems, frequency is the continuously changing variable which is influenced by the power generation and demand. A generation deficit results in frequency reduction while surplus generation causes an increase in the frequency.
Challenges of frequency regulation in modern power systems Frequency regulation, a method for assessing grid stability following a disturbance or fault, is evaluated by considering frequency nadir, steady-state deviation, a dynamic rolling window, and the rate of change of frequency.
Power systems maintain frequency within the limits defined by grid codes by dynamically matching the generation and demand for secure operation. Large frequency excursions cause the tripping of loads and generators, which may lead to system collapse [, , , ].
