Supplemental Data Requests and Collection When requested by the WECC community, WECC staff, or other stakeholders the DS and SDWG will consider collecting additional data related to the system models that it maintains to assist in better studying the transmission system or managing compliance obligations. These requests are ad hoc and have their own deadlines per project. After collecting the data for a specific need SDWG will evaluate if the new fields should be added to the base case requirements though the DPM. Some examples of extra data that has been collected in the past are: RAS and contingency models GIC data Overcurrent relaying Substation definition data BA definition data Current future data sets that may be considered: Circuit data Data maintainer Generator protection relays Distance relays Support of the Anchor Data Set The SDWG will assist in developing the Anchor Data Set (ADS) on a biannual basis in support of aligning the Production Cost Model and Power Flow Modeling topology. Despite the biannual nature of the ADS it is anticipated that this work product will be ongoing for the first couple cycles to insure the quality of the ADS continues to improve. The SDWG will support the Anchor Data Set Task Force and the PCM Data Work Group in developing processes and insuring that collected data supports the needs to the WECC community. The SDWG will use existing work products as applicable and may develop new processes as necessary.
