The following methods are used to evaluate the accuracy of the state estimator results:

 Continually monitor and minimize the amount of bad data detected by correcting model, telemetry, and bad status.

 Compare critical telemetry with the state estimator solution (ties, major lines, large units, etc.).

 Use measurement error/bias analysis to detect and resolve telemetry and model problems.

 Periodically review all stations to correct high residuals and minimize all residuals as much as reasonably possible.

 Compare CA results to actual system.

 Compare power flow results with actual system.

 Compare state estimator actual violations to see if they closely match actual SCADA violations.

 Compare state estimator total company load/generation/interchange integrated over time to see if it closely matches billing metering.
