4 Generation Testing Implementation Plan Responding to a PCC assignment of TSS/MVWG, Generator Testing Task Force (GTTF) prepared a Generation Testing Implementation Plan (GTIP) GTIP includes: transition plan for the new Generation Testing Policy Clarification on the treatment of identical units within the same power plnt

5 Generation Testing Implementation Plan – Issue 1 Issue 1: Generator Owners who did not perform baseline testing in accordance with the original requirements are non-compliant with the Policy. Issue 1 Response/Implementation: Generator Owners that are non-compliant with the baseline test requirement (as defined in section B.1.2 of the Policy) shall provide to WECC staff, by December 31, 2006, a schedule to perform baseline testing and model validation. The Generator Owner should coordinate the schedule with the appropriate Transmission Planner (s). The Generator Owner will be considered non- compliant with the Policy until the baseline testing and model validation is completed.

6 Generation Testing Implementation Plan – Issue 2 Issue 2: A large number of Generator Owners, who complied with the original baseline test requirement, are required to perform model re-validation. Spread generator re-validation over a five-year period. Coordinate the re-validation efforts with the respective replacement programs, as well as maintenance cycles. WECC should have the authority to accept or reject the re-validation schedule proposed by the Generator Owners.

7 Generation Testing Implementation Plan – Issue 2 (continued) Issue 2 Response/Implementation : Generator Owners that have complied with the baseline test requirements (as defined in section B.1.2 of the Policy) shall provide to WECC staff, by December 31, 2006, a schedule to perform model re-validation (as defined in section B.1.3 of the Policy). The Generator Owner should coordinate the schedule with its the appropriate Transmission Planner(s). The Generator Owner will be considered compliant with the Policy as long as the initial model re-validation is completed within 5 years from December 31, or from when the baseline test and model validation was first completed; whichever comes first. Subsequent model re-validation should be done every 5 years.

8 Generation Testing Implementation Plan – Issue 3 Issue 3: Baseline testing and model validation of the sister units in the same Generating Facility. Issue 3 Response/Implementation: In case of multiple identical generating units at the same Generating Facility, baseline testing (as defined in section B.1.2 of the Policy) shall be performed on at least one of the representative units. Model data validation (as defined in section B.1.3 of the Policy) shall be performed for all generating units.

9 Generation Testing Implementation Plan – Issue 4 Issue 4: Wind Farm Model Validation Issue 4 Response/Implementation: The technical guidelines developed in conjunction with the Policy, as well as existing WECC generator testing guidelines, apply to conventional generating units. Similar guidelines will be developed to address model data and model validation requirements for wind power plants. Those guidelines will go through the WECC approval process.

10 Proposed Motion TSS Requests PCC Approval of the Generation Testing Implementation Plan

11 WECC Dynamic Modeling Procedure Purpose Establish procedure for development and maintenance of models, and for the submittal of data to WECC. Improve the quality of the WECC Master Dynamic Data File Assist WECC staff in managing submittals of models Clarify modeling procedure for WECC members Improve interaction with program developers Identify need for new models and improvement to existing models Identify and report compatibility and conversion issues

12 WECC Dynamic Modeling Procedure (continued) MVWG is the WECC group responsible for assuring the model database is kept up to date. Any models added to the WECC master dynamic model library require acceptance from MVWG. This Procedure will formalize the process for MVWG acceptance. The Dynamic Model library will be posted on WECC website.

13 Load Modeling Development Status WECC-CIEE/PIER MOU approved by BOD Air-conditioner testing and modeling Load composition analysis (component data base) Load monitoring (white paper) Load data uncertainty analysis Finalized specification for Composite Load Model Architecture and Prototype Load Model Data Tool under development Going Forward Implement composite load model in PSLF Version 1.0 (without single phase motor model) Solicit bids and contract for load model data tool Load model validation (some validation base cases created)
