13.2.7 Droop problem: how I think about it

USA = 60 Hz (problem could specify something different)

Droop percent = 5% so 60 Hz X .05 = 3.

There are 30 increments of .1 in three

Unit size is 600MW (whatever from the problem).

To get MW/Hz divide MW by Hz

600/30 = 20 MW change per .1 Hz difference

Problems often say something like: Frequency is at 59.3 Hz, so there is a .7 Hz change from 60 Hz.

20 MW/.1 Hz times 7 increments equals a 140 MW change.

There may be another step because the question could say: Unit started at 300 MW, what is the new output?

In this case, add the 140 MW to 300 MW and end up with a new output of 440 MW.

(NI_A − NI_S) − 10B (F_A − F_S) – I_ME

NI_A – Net Actual Interchange 

NI_S – Net Scheduled Interchange

10 – Factor to make (F_A − F_S) bigger

B  – Frequency bias (each BA responds to adverse conditions a little bit, to help out)

F_A – Actual Frequency

F_S – Scheduled FrequencyI_ME – Meter Error (nobody cares, not used in operations)
