Evaluation of State Estimation performance on the IEEE 118-bus System, typically measured using Mean Absolute Error (MAE) and Normalized Performance.

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.

| Scope | Recorded value |
| --- | --- |
| Task | State Estimation |
| Dataset (including any stated split) | IEEE 118-bus System |
| Metric | MAE |
| Unit | SCALAR |
| Direction | Lower is better |
| Results loaded | 4 of 4 |
| Coverage | All results currently returned for this benchmark |

Evaluation settings may differ between results. The original papers and recorded configurations are needed to establish comparability. A shared metric name alone does not establish an identical protocol.

## Metrics

- [MAE](<https://www.sota2.com/research/sota/state-estimation-on-ieee-118-bus-system.md?metric=MAE>): Lower is better; unit: SCALAR.

- [Normalized Performance](<https://www.sota2.com/research/sota/state-estimation-on-ieee-118-bus-system.md?metric=Normalized%20Performance>): Higher is better; unit: PERCENT.
