Dynamic Model Data Management ERCOT SYSTEM PLANNING
Current Process Annual Flat Start Case Build TSPs DWG ? =? REs ERCOT RARF
Proposed Process • Resource Entities (REs) submit all dynamic models and parameters through RARF to ERCOT. • ERCOT will inform TSPs about the updated model and parameters. • TSP and ERCOT will work with REs to resolve any concerns on the submitted model and parameters. • ERCOT will be a single source to collect and compile all REs’ dynamic models and parameters and provide the data set to DWG for flat start base case creation.
Proposed Process: Flat Start Case Build Creation DWG Periodic Updates TSPs REs ERCOT RARF Resolve model and parameter concerns
Draft of NERC MOD Standard • MOD-026-1, MOD-027-1, MOD-025-2 • These draft standards applies to Generator Owner and Transmission Planner • Considering RARF is the adopted process in ERCOT region to collect all the model data, potential changes may be required in the future once these standards become effective
Potential changes: for NERC MOD-26-1, MOD-27-1 RARF with accepted model and parameters Flat Start Case Build Creation REs ERCOT DWG Updated Models and Parameters Acceptance Notification TP
Next Steps • Discuss with DWG • Pilot? • DWG Procedure Manual Changes?
