Description

technical field [0001] The invention relates to the field of power grid frequency regulation optimization, and more specifically, relates to a frequency regulation auxiliary service optimization system and method considering the frequency regulation performance of a unit. Background technique [0002] The essence of frequency modulation is to perform real-time balance of active power. According to the operating characteristics of the Southern Power Grid, the main reasons for power changes are: first, power fluctuations caused by load forecast deviations and random changes; second, system failures that may cause generator trips, safety automatic device cut-offs, and partial grid disconnection , Some users have power outages, etc., which cause the system power to lose balance. When the power imbalance occurs in the system, the frequency will change and deviate from the normal control range. A series of power adjustments are required to bring the system back to a balanced stat...
