Starting Point Selection
A Starting Point Selection Approach to Event Playback for Model Validation
Analytical basis of this method shows the existence and uniqueness of the trajectory of the underlying model.
About
To overcome the deficiency of the conventional “event playback” approach, a starting point selection approach is used to renovate the “event playback” by focusing on low-frequency responses in model validation. Analytical basis of this method shows the existence and uniqueness of the trajectory of the underlying model. The effectiveness of this approach has been demonstrated using the two-area four-machine system model.
Key Benefits
• This approach can save the cost from a staged test, and service interruption compared to the offline model validation approaches. • This approach can overcome the difficulty of PMU based model validation when high-frequency responses are incurred, and therefore make the validation procedure more applicable using the responses from major dynamical events (such as line faults and generator tripping).
