2. Goal: help industry to better meet NERC compliance requirements
More stochastic and dynamic behavior observed in today’s power grid
Good model quality is critical for secure and economic planning and operation
WECC policy and NERC standards requiring periodic model validation 2

3. Key Innovation of TIP352 project
Sponsored by BPA TI and DOE Advanced Grid Modeling (AGM) program
Gaps
Not easy to prepare cases for model validation studies
Link to PMU measurements
Link to operational information
Available calibration techniques are standalone tools, not integrated with validation function in commercial packages. Not easy for users
We are developing a more integrated tool
Directly use real-time EMS cases for validation
Ease of use in creating archives of data needed for model validation/calibration, e.g., PMU data, EMS snapshots and calibrated parameters 3
