Frequency response too slow
Hi guys in my dynamic simulation of a generator tripping event, the frequency recovered very slowly from the lowest point (the Nadir point or Point C in NERC's definition) to the first stable point (Point B By NERC). This simulation is to replicate a historical event which actually recovered pretty fast, only 8sec from Point C to Point B, while my simulation takes 20 to 30 secs. Any idea what could be reasons? Thanks a lot!

Any idea what could be reasons? Thanks a lot!

Added on Mar 25: To all experts on this matter, can you list the factors that affect the recovery rate of frequency from lowest point to the first stable point? I have tried load response rate, amount of available generator governors, and droop characteristics. However, if I adjust some of these factors to provider faster frequency support, then my Nadir point could be too high compared to actual.
