PDCWG Meeting July 1, 2014
• Reviewed June frequency control.– Improved CPS1 & 2.– Frequency Profile continues to be on the high side.
• Causes were discussed: More small high frequency “events” (small up swings in frequency). Non-conforming load MW change larger on “turn-offs” than “turn-on” would contribute to larger upswings. Must have data to prove.
• Wind turbines help with high frequency but typically not with low frequency. This keeps high frequency limited to a tighter profile on the high side.
• Two “Normal” curve profiles were suggested.– Fewer Time Error Corrections in June.

PDCWG Meeting
• BAL-001-TRE– Implementation timeline was discussed. ERCOT and
TRE will meet to confirm dates.– Resources requesting a waiver from the standard as
allowed in the standard requested the process for confirming the waiver.
– RARF additional information needed for conventional steam turbines. A revision request will be written.
– Protocol and Operating Guide revisions will be needed and are being developed.

PDCWG Meeting
• Reviewed June 21 frequency event.– RRS providers had 5 Resources with below expected
performance.– Non-RRS providers had 4 Resources with below
expected performance.• Reviewed June 7 frequency event.
– RRS providers had 2 Resources with below expected performance.
– Non-RRS providers had 9 Resources with below expected performance, poor data or inaccurate HSLs.

PDCWG Meeting
• Reviewed June 23 frequency event.– RRS providers had 4 Resources with less than
expected performance.– Non-RRS providers had 8 Resources with less than
expected performance due to either on augmented energy or errors in their HSL.
• Interconnection Primary Frequency Response was excellent during each event.– -694 MW/0.1 Hz, -847 MW/0.1 Hz and -1215
MW/0.1 Hz during the 21st, 7th and 23rd events.

PDCWG Meeting
• ERCOT will provide the PDCWG an estimate of System Inertia data in each Frequency Disturbance Report prepared for the PDCWG.
• A request for high speed frequency data on each event was requested.

Notes
• Time error values from NRG True Time device can be slightly different from ERCOT’s Time Error but the daily delta times should be accurate.
![Page 22: PDCWG Report to ROS](https://reader036.vdocument.in/reader036/viewer/2022081603/568139c8550346895da17600/html5/thumbnails/22.jpg)
Time Error Corrections
• Four slow Time Error Corrections were executed in June.
• Other than the days with the TECs, 3 days had positive time error.
