    1. Advanced System Simulation to Support Operator Training Idaho Center of Excellence Electricity Infrastructure Operations Center Idaho National Laboratory Pacific Northwest National Laboratory Presented to the NERC RC Trainers July 12, 2007

    2. Introduction WHO are we? Michael Assante - INL Jeff Dagle – PNNL Rick Byrne - NERC WHY are we here? Explain concept WHAT do we want today? Feedback on concept

    3. What is the Idaho Center of Excellence (ICE)? Combined effort of Idaho National Labs and Pacific Northwest National Labs Promotes advanced control systems testing and training for the electric industry

    4. Rationale Meets 2003 Blackout recommendations for advanced training An incremental upgrade on current INL/PNNL work Captures and applies knowledge from aging workforce Promotes excellence in training programs Establishes relationships with vendors to improve training and product

    5. Emulator Features More realistic and advanced More accurate and detailed models and calculations than in classic simulators Mimics the dynamic nature of system components Allows for continuous activity Multiple users on a scenario Flexibility for different types of training Users operate on familiar interface

    6. Real-Time Electric System Modelling and Testing Ability is a Vital North American Need Real-time electric system modeling capability is essential for: Simulating wide-area energy systems Testing system contingencies Effective equipment testing: SCADA RTUs Relays PLCs EMS, etc.

    7. RTDS Racks used by Grid Operators World-Wide

    8. Expand Real-Time Simulation Ability Real-time electric system modeling boosts SCADA testing capability … Would you test SCADA with off-line software models that emulate a few commands?

    9. Add Realism to Operations/SCADA Training/Evaluation

    10. Real-Time Simulation Equipment is Industry Proven and Scalable

    11. Real-Time and Dynamic Simulations Give Real-World Inputs

    12. Engineering Draft File Defines The System (Connections, Models, and Parameters)

    13. Operator Run-Time Interface is One Form of a Power System Control Board

    14. Example of How a Load Flow Contingency Analysis Can Mislead

    15. Dynamic Simulation Voltage Magnitude Results Show That All Is Not Well …

    16. System Models Must Include Load Dynamics Bus 6 to Bus 7, Line 1 trip by SCADA Bus 9 to Bus 10, Lines 1 and 2 trip by relays Type of control necessary to successfully damp oscillations depends on load dynamics

    17. Load Dynamics Significantly Influence System Stability

    18. How Large of a Model Is Necessary?

    19. Divide the System Into Regions Use System Equivalents Outside Test Area

    20. Multi-regional Training

    21. Additional Roles for the Emulator Training for other key personnel Planning model validation Real-time contingency analysis Control and protection equipment testing and qualification Cyber security scenarios

    22. Vision for the Future Recruit expert volunteers Work with a few utilities to develop prototype demonstrations (proof of concept) Progress to larger areas, more complex models Bring training coordinators/senior operators to the center to develop scenarios Train the trainers and system operators at the center Develop wide area training capability (regional training centers, asset-owner training center) Obtain current network models from participating utilities Obtain current dynamic data to populate scenario models

    23. Questions?

    24. Real-Time Test Center Will Expand North American Testing Capabilities Model Actual Grid NA Simulate/Run Abnormal System Conditions: Extended Duration Faults Power Swings Voltage Collapse Cascading Overloads Equipment Outages Test RAS Effectiveness Test Wide-Area Schemes

    25. Area of Interest Shown in Red

    26. Area Details Remain Intact While Preserving Overall System Dynamics

    27. We Need to Validate Electric System Response to SCADA Disturbances

    28. We Need to Test SCADA Response to Electric System Disturbances Power swing blocking and tripping Eliminate “best-guess” compromises Bus protection operation Breaker failure operation Generator Dynamics: Non-optimal PSS AVR limits IPP Start-up/Shut-down sequencing Load rejection Load-shed schemes

    29. Reliability Coordinator Training
