December 16, 2011 GADS Open Source Release

by ronfluegge 31. December 2011 01:19

I will provide more details on each item below, but in summary, the December 16, 2011 GADS Open Source release already posted to the download/install sites will work just fine … no updates or reinstallation is necessary.  Some manual settings may need to be changed as indicated below if the 3 items below apply to your situation.

However, if you ONLY collect/report “gross” capacities (GMC, GDC and GAC … in other words, no NMC, NDC or NAC at all) AND you only want to report the minimum “required” GADS data to NERC, you have two options discussed as a part of Item (3).

(1) ISO-NE

In our 12/23/2011 email, we indicated that we had received an email from the ISO-NE entitled “Changes in GADS Reporting Requirements as of January 1, 2012” dated December 21st indicating that their reporting requirements have changed.

Quoting the referenced email, “ISO New England (ISO-NE) has been working with NERC to become the Delegated Reporting Entity (DRE) for the New England region generators. This has been done to ease the burden on participants by allowing one data submission to ISO-NE. We will then be responsible for forwarding the data to NERC.  While we require units 5 MW and higher to submit the required dataset to ISO-NE, we will only forward data for units with nameplate ratings of 50 MW or higher in 2012 and for units 20 MW and higher starting in January 2013 -- unless you specifically ask that we forward data for smaller units to NERC.

“When ISO-NE has submitted the data to NERC, you will receive a notice from NERC’s webGADS data submittal system.  If NERC finds problems with the data, or if the data was not submitted by the deadline, they will contact the generator owner and also notify the appropriate data submittal agent(s) of the problem.  In other words, the ultimate responsible party for the timely submittal of accurate data is the generator owner.”

For generating units 50 MW and higher, data must be submitted for all the required fields as noted in the spreadsheet attached to the email you should have received from ISO-NE to be in compliance with NERC.

Since ISO-NE will be submitting the NERC required data on your behalf, you will simply select “NERC Format” instead of “ISO-NE Format” under the “Write Data” menu item in DE or select NERC in the Dashboard. 

Then when writing out your GADS data, also simply check the box for “Write expanded 05/07 data format”. 

If you want to submit only the NERC “required” data, uncheck “Write ALL Data Including Voluntary to NERC”.  If “Write ALL Data Including Voluntary to NERC” is CHECKED, all GADS data fields (required AND voluntary) will be included in the 05/07 ASCII files.

(2) NYISO

We also indicated that we had sent an email to NYISO asking if they too are planning similar changes.

In their 12/28/2011 reply to our email, in summary they write:  “The NYISO will not be reporting data to NERC on behalf of generators at this point … We have told our MPs that they will need to submit their data in the 05-07 format beginning with the January [2012] data.“ 

When writing out your NYISO data beginning January 2012, simply check the box for “Write expanded 05/07 data format” before pressing the OK button.

(3) NERC

During our code and changes review, we requested clarification from Mike Curley, Manager, NERC GADS Services, on several identified items.

There is some apparent conflict in the NERC GADS DRI on what is required.  The 2012 DRI states that the NMC, NDC, NAC and NAG are REQUIRED and GMC, GDC, GAC and GAG are voluntary

The DRI states that the Net capacity values are REQUIRED on the Performance data (Figure IV-2 Record Layout of Section B – Unit Generation Performance) and derating Event data (Figure III-5 Record Layout of Section B – Event Magnitude) as shown below:

Gross Maximum Capacity (GMC) (Record 01, columns 16-21) - Voluntary
Gross Dependable Capacity (GDC) (Record 01, columns 22-27) - Voluntary
Gross Actual Generation (GAG) (Record 01, columns 28-36) - Voluntary
Net Maximum Capacity (NMC) (Record 01, columns 37-42) - Required
Net Dependable Capacity (NDC) (Record 01, columns 43-48) - Required
Net Actual Generation (NAG) (Record 01, columns 49-57) – Required

Gross Available Capacity (GAC) as a Result of the Event (Record 01, columns 56-61) – Voluntary
Net Available Capacity (NAC) as a Result of the Event (Record 01, columns 62-67) – Required

The DRI also states:  “For consistency in calculating statistics, if Net Actual Generation [NAG] is reported (negative integer or positive integer), NMC or NDC must also be reported.” (emphasis /clarification added)

Based on the DRI, when writing out the “required” data fields with the December 16, 2011 GADS Open Source release, only the Net values are written out in the 05/07 files; no Gross values.

We posed the following questions to Mike Curley:  “So if a generator does not now collect Net values and only submits one or more Gross values will it pass OATI/NERC’s edit checks?  Or must the required Net values be estimated and submitted to pass?”

His response on 12/23/2011 was:  “Only NAG and any one of the capacities is required.” (emphasis added)

However, if you submit only one capacity or gross capacities only, the NERC editing program will apparently calculate any missing GMC, GDC, NMC, or NDC using the following criteria:

Fossil, Nuclear, and Fluidized Bed:  5.0% difference between gross and net values
Gas Turbine/Jet Engine:  2.0% difference between gross and net values
Diesel:  No difference between gross and net values
Hydro/Pumped Storage:  2.0% difference between gross and net values
Miscellaneous:  4.0% difference between gross and net values

For example, if you report only GMC and GDC for a Fossil unit, then the program will take your GMC and multiply it by 0.95 to determine the new NMC. The same operation would occur for determining the NDC from the GDC number.

If you report only one capacity (for example GMC), then the program will assume the GMC and GDC are equal and will record the unit as such. It will then calculate the NMC and NDC using the calculation stated above.

According to the DRI, if you think the differences between gross and net are different than those numbers stated above, then “complete all capacities (maximum and dependable) with the correct numbers”.

NERC will also use the delta (difference) between your gross and net capacities from your performance records to calculate the differences between GAC and NAC on your derating event records!

Remember that when NERC calculates all of your “equivalent” factors and rates (e.g., EAF, EFOR, EFORd, etc.), they use the capacities to calculate the per cent derating when determining the equivalent hours and in calculating all capacity-weighted statistics for your units.

If you ONLY collect/report “gross” capacities (GMC, GDC and GAC … in other words, no NMC, NDC or NAC at all) AND you only want to report the minimum “required” GADS data to NERC, you have two options:

1. Using the December 16, 2011 GADS Open Source release, CHECK “Write ALL Data Including Voluntary to NERC” and all GADS data fields (required AND voluntary including all Gross capacities) will be included in the 05/07 ASCII files.  Note you must still input the Net Actual Generation (NAG) as required by NERC.

2. We will be posting a 12/30/2011 release tomorrow that writes out the available NERC-identified required data plus the Gross capacities if you only input Gross values if you so choose.  Download and install this version.

If you have any questions, please give me a call.


 

ISO-NE Changes in GADS Reporting Requirements as of January 1, 2012

by ronfluegge 23. December 2011 16:46

We just received an email from the ISO-NE entitled “Changes in GADS Reporting Requirements as of January 1, 2012” dated December 21st indicating that their reporting requirements have changed.

As a result, we are reviewing our code to ensure that the GADS performance and event files created for ISO-NE for 2012 meet these requirements.

If you submit data to ISO-NE and …

• have not already downloaded the 12/16/2011 update, please wait until we have made these necessary code changes.  
• have already installed the 12/16/2011 update, we would recommend that you download and install the upcoming update when it is available.

We expect to post the ISO-NE update on or before December 30th.

We have sent an email to NYISO asking if they too are planning similar changes.

You will get a follow-up email when the update(s) is posted.

GADS Open Source Version 11.12.16.0 Update

by ronfluegge 16. December 2011 17:33

We have just posted to the websites GADS Open Source Version 11.12.16.0.

Because this release includes NERC GADS mandated changes for 2012, we highly recommend that you install this update.

This is GADS Open Source Version 11.9.9.0 of the Windows UI that has been updated to address the 2012 GADS changes received from NERC as recently as December 12th and the issues as listed below.

Note:  We are modifying the GADS Open Source software to give you the choice to submit to NERC only the mandatory (required) data or the entire GADS data set. 

You will still be able to collect all of the data such as fuel data, event verbal descriptions, etc. but only the data "you choose" will be written into the 05/07 file to be sent or uploaded to NERC/OATI.

If you are a non-North American user, you will not be affected by these changes unless you indicate that you are planning to submit data to NERC in the Unit Setup Console software.  The changes you will see, such as the event verbal description no longer being a required field, will be available to both North American and international users.

----------------------

Manual Settings Changes Required (Users submitting to NERC ONLY)

Unit Setup Console 11.12.16.0 - Manual Settings Changes Required (Users submitting to NERC ONLY)

1. On tab 3 for each unit ensure that "Display the Cause Code Extension / Amplification Code field" is CHECKED
2. On tab 3 for each unit ensure that "User can also enter custom values (editable)" is NOT checked.
3. Make sure that you have installed and run the Cause Code Updater application.
4. With full event data reporting, including RS events, now a requirement for most generating units, on tab 2, if your event reporting has changed over time (e.g., in January 2012, you now start reporting RS events), you should enter that change in event reporting using the button on the bottom right.  This ensures that Analysis correctly calculates the factors and rates for the units.

Data Entry 11.12.16.0

1. The default option when writing NERC data is to write out only the REQUIRED data.  If you want to write out ALL GADS data, check "Write ALL Data Including Voluntary to NERC" to write out both the required AND the voluntary NERC GADS data to the files.  Make sure that "Write expanded 05 / 07 data format." is checked when writing files to send to NERC/OATI.

Dashboard 11.12.16.0

1. The default option when writing NERC data is to write out only the REQUIRED data.  If you want to write out ALL GADS data, check "Write ALL Data Including Voluntary to NERC" to write out both the required AND the voluntary NERC GADS data to the files.  Make sure that "Write expanded 05 / 07 data format." is checked when writing files to send to NERC/OATI.

----------------------

Code Changes

Data Entry Admin Console 11.12.16.0

1. Can now create a default location to write out the NERC and ISO ASCII files

Data Entry 11.12.16.0

1. The default option when writing NERC data is to write out only the REQUIRED data.  If you want to write out ALL GADS data, check "Write ALL Data Including Voluntary to NERC" to write out both the required AND the voluntary NERC GADS data to the files.  Make sure that "Write expanded 05 / 07 data format." is checked when writing files to send to NERC/OATI.
2. Confirmation of event record deletion on Submit
3. Confirmation when deleting (Rev X) any event
4. Added Browse button to select a folder other than the default when writing ASCII files
5. New cause codes for Pumping (9345) and Synchronous Condensing (9340)
6. Event Verbal Description field is no longer mandatory ... can be left blank.
7. NC events can have available capacities > 0 -- No NC event records in GADS ASCII file per NERC

Changes required by NERC and PJM

8.  Changed D1 validations per NERC – Amp Codes no longer required
9.  All U1s must have an Amp Code (PJM only)
10. All transition U1s - any Amp Code except Amp Codes T1, T2 or 84, or none per NERC
11. All U1s from online - only Amp Codes T1, T2 or 84 allowed per NERC
12. No NC event records in GADS ASCII file per NERC

Dashboard 11.12.16.0

1. The default option when writing NERC data is to write out only the REQUIRED data.  If you want to write out ALL GADS data, check "Write ALL Data Including Voluntary to NERC" to write out both the required AND the voluntary NERC GADS data to the files.  Make sure that "Write expanded 05 / 07 data format." is checked when writing files to send to NERC/OATI.
2. Changed individual event record deletion functionality to mark records for deletion.
3. Added Delete All Events tab

Analysis Admin Console 11.12.16.0

1. A new tab, "Delete All Data", has been added.  This allows you to reset all Analysis & Reporting tables that are mirror-images of the Data Entry event and performance data tables. This essentially forces the software to snapshot all of the data from the Data Entry data tables and to recalculate all the historical data. This is useful if you need to “start over” for any reason.  If you click "Yes" on the two confirmation message popups, the GADS data will be deleted from the Analysis & Reporting tables and will have to be reloaded from DE for the program to have data to use in the calculation process. This option is useful when it is necessary to start over; for example, when it appears that the data in the Analysis & Reporting tables has been corrupted.

Analysis 11.12.16.0

1.  Modified Chronological Event Listing to show contribution code 3 event records if selected
2.  Added list of selected units to footer for custom unit selections when selecting the “Summary Only” option   
3.  Modified code to allow for sorting for Event Details with Cause Code Extensions report
4.  Individual Events | Customized Event Records report allows sorting
5.  The menu item "Delete all Event and Performance Data" to delete all AR performance and event input data has been moved to the AR Admin Console.
6.  Added report to export to Excel NYISO-specified GE MARS input data
7.  Checking "Suppress Page Breaks on Report" suppresses the page breaks on some of the reports (e.g., Chronological Events Listing) so that it prints fewer physical hardcopy pages.
8.  On the Event Details Report the MWh LOA column has been widened to allow for bigger data to be displayed.
9.  Corrected a bug in the Chronological Events Listing report for units in IR and MB status
10. Corrected a bug when running User-defined or Peak Period Set reports

 

If you do install any of the above updates, we recommend a full update of ALL GADS/OS apps.

If you plan on using Microsoft Access for your storing your GADS data, you cannot use Windows XP; however, you can use Windows Vista or Windows 7.  When datasets from Microsoft Access are loaded into SAP Crystal Reports, Crystal Reports generates the unhandled exception that we cannot trap or fix.  This only occurs when running Analysis & Reporting on Windows XP in combination with Access databases.  If you are not able to switch to Windows 7, we recommended using SQL Server 2005 Express or SQL Server 2008 R2 Express (with tools) instead of Microsoft Access (SQL Server Express is free from Microsoft).  We can assist in installing SQL Server Express on your machines if you would like to implement this solution.  Or you can change your machines to Windows 7.

The full installation and source code can be found at

http://gadsos.codeplex.com/releases/view/65217

Except for bug fixes, the next major release is currently scheduled for May 2012.

If you have any questions or encounter any problems, please give me a call.  Our hours of operation are Monday through Friday 8:30 AM to 5:30 PM Central Standard Time. Please note that my team’s offices will be closed on Friday 12/23/2011 and Monday 12/26/2011 in observance of the Christmas holiday.  The offices will also be closed on Friday 12/30/2011 and Monday 01/02/2012 in observance of the New Year's Day holiday.

I wish you happy and safe holidays on behalf of the entire Project team.
