Handbook for Planning Data Services <br />7. ERCOT Dynamics Database <br />Description: <br />Make available Owner data required for updating the ERCOT dynamics databases. <br />Section 6.2 of the ERCOT Planning Guide states: "The Facility owner shall provide <br />appropriate dynamics data to ERCOT including the data for a planned Facility. <br />Dynamics data for a planned Facility will be updated by the Facility owner upon <br />completion of the design for the Facility. Updated dynamics data for an existing Facility <br />shall be provided to ERCOT when field tests, inspections, or other information <br />demonstrates that the dynamics data should be changed to accurately represent the <br />dynamic characteristics of the Facility. "To meet the requirements of Section 6.2, LCRA <br />and Owners will perform the following: <br />Owner Shall: <br />1. Provide the load composition data necessary to develop load models for use in <br />dynamic simulations (Also see Section 3- ALDR). <br />2. Provide the location, settings, and estimated load to be interrupted. Estimated load <br />should be the consistent with the seasonal peak and off -peak loads used in the <br />ERCOT SSWG Dataset A cases (Also see Section 4- UFLS). <br />3. Provide vendor data for dynamic equipment (e.g., static var compensation) <br />connected to the system. Data shall be appropriate for development of a dynamic <br />model to be included in the ERCOT Dynamics Working Group (DWG) Flat Start <br />cases. When available from the vendor, the vendor should be requested to provide a <br />dynamics model compatible with the current version of software used to develop the <br />DWG Flat Start cases. <br />4. Facilitate the acquisition of data needed to develop the dynamic models to be <br />represented in the DWG Flat Start cases for resource Entities with facilities <br />connected to Owner's system. <br />5. Be accountable for the data produced including accuracy, timeliness, and <br />completeness. <br />6. Provide a name and contact information to include with the data submittal to ERCOT <br />as necessary. <br />11 f Pag, Rev, 0 <br />
