  • Design/Performance/Event Data
  • Common Errors
  • Example Scenarios
  • GADS Software
  • Use of GADS Data
  • Panel Discussion

 

Who Should Attend:

 

The GADS Seminar is intended for individuals directly responsible for handling the submittal of their organization’s generating availability data, or for those individuals who support that function.

NYISO Generating Availability Data System (GADS) Portal Tutorial

by ronfluegge 6. December 2014 15:51

Generating Availability Data System (GADS) data is required by NYISO to determine the amount of capacity available for the Installed Capacity Market and to evaluate the reliability within the NY Control Area. The data is used to calculate the De-rating Factors for the NYISO Capacity Market. GADS data is used as an input into NYISO and the New York State Reliability Council's (NYSRC) Reliability Studies, specifically the Annual Installed Reserve Margin (IRM) Study for the New York Control Area and the NYCA Locational Capacity Requirements calculation. There are three types of data:  Design Data identifies the unit as an unique entity; Performance Data provides a summary of unit operation for a month; and Event Data consists of specific data for each event.

The NYISO GADS Portal accepts Performance and Event data.

The NYISO GADS portal enables Market Participants to upload standard GADS data files or to enter GADS Data directly via a user interface. MPs can edit/correct data errors identified during the submittal process. For example, users have the ability to correct a specific event start date or end date. The portal can also provide MPs with a standard 12 month ICAP EFORd report which captures a rolling 12-month period.

The NYISO GADS Portal was built by the GADS Open Source Project for the NYISO and can be accessed on the ICAP page of the NYISO website. 

In order to become an authorized user and submit GADS data through the portal, Market Participants will require a digital certificate and must be granted access to the portal. The GADS Administrator at the NYISO will provide access and each authorized user will have a User Name and password to access the Portal. The User Name will be the MIS User account name and the password entered will be their MIS password. Those MPs having an existing MIS account can request additional access to the GADS portal through the NYISO’s GADS administrator

This Portal training is meant to provide a high level introduction to the NYISO GADS Portal as part of the October 2014 deployment. This presentation assumes previous knowledge of GADS data and familiarity with the NYISO requirements.

For more comprehensive information on the NYISO GADS Data requirements please refer to the NYISO Installed Capacity Manual.

For more detailed information regarding the entire functionality of the NYISO GADS Portal, refer to the GADS Portal User’s Guide.

Procedure for Establishing New York Control Area Installed Capacity Requirements

by ronfluegge 11. August 2014 23:59

Our GADS Open Source software has been included in the New York State Reliability Council’s Policy No. 5-8 - Procedure for Establishing New York Control Area Installed Capacity Requirements (see attached or go to http://www.nysrc.org/policies.asp )

"The multi-state model for each unit is derived from the collection of forced and partial outages that occur over the most recent five-year period using benchmarked GADS Open Source (OS) software as described in Appendix E."

Search the document for “GADS”, but pay specific attention to Appendix E - Development of Generator Transition Rate Matrices for MARS that are Consistent with the EFORd Reliability Index

Beginning on page 33 and continuing on page 34:

“In order to generate the metrics needed to populate the transition rate matrices for the generating units modeled in MARS, the above methodology was coded into the GADS Open Source software package but modified as described above. The GADS Open Source (GADS OS) is the software utilized by the NYISO to analyze generator performance data. It is used to calculate the generator performance indexes used in determining a generator’s UCAP value and, now, for developing the transition rates that are used in the MARS model. GADS OS allows electric generating companies to collect and report validated GADS performance data and event data. GADS OS can be found at this link:

http://gadsopensource.com/

“GADS OS, written by industry veteran Ron Fluegge, consists of two open source applications— GADS OS Data Entry and GADS OS Analysis & Reporting to analyze the GADS data. Besides the use of this software for submittal of GADS data to NERC and the NYISO, the software is also used for submittal of data to the ISO New England, PJM, and the MISO.”
