Abstract

See full text

Provided are a method and apparatus for evaluating a degree of frequency regulation urgency of a generator set, a power system and a storage medium. The method includes obtaining a power grid frequency fluctuation trend under a normal operation condition and a power grid frequency fluctuation trend under a fault condition through simulation analysis based on the proportion η of the installed capacity of each of multiple types of generator sets in a regional power grid; obtaining a degree P of frequency regulation participation of each of the multiple types of generator sets based on the power grid frequency fluctuation trends under the normal operation condition and the fault condition; and calculating a degree U of frequency regulation urgency of each of the multiple types of generator sets in a power system based on the degree P of frequency regulation participation of each of the multiple types of generator sets and the proportion η of the installed capacity of a respective type of generator set corresponding to the degree P of frequency regulation participation, and implementing frequency regulation participation of the regional power grid in the power system based on the degree U of frequency regulation urgency.
