During the dynamic operation of a power system, unpredictable changes in load result in deviations in both frequency and voltage from their intended levels, posing challenges such as line tripping and ...

Firstly, the aggregated system frequency response (SFR) model is constructed by reducing the order of the generator governor equation, the EFC equation, and the load model equation. Then, based on the ...

The emergency frequency control of high-voltage direct-current (HVDC) receiving-end grid is investigated in this paper. While the multi HVDC feed-in system has several potential frequency stability ...

However, the conventional under-frequency load shedding (UFLS) scheme doesn’t take into account the impact above, resulting in unreasonable load shedding after a large loss of generation. To this end, ...
