Regional Load Flow Voltage Regulation Package

Calculates deterministic SSC-05 regional load-flow metrics from a task-owned synthetic source pack. The template combines load growth, transformer loading, feeder current, voltage drop, regulator boost, minimum-voltage margin, PFC requirement, feeder loss, and an overall synthetic pass score.

with-tool: The model is given an executable Python calculator script.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

All inputs remain visible at every tier

For this template, difficulty scales through parameter and scenario ranges rather than hidden information.

Scenario archetypes

Each generated task is drawn from one of these realistic scenario bands.

Site contexts ground each scenario in a real locale the model can use to infer hidden values.
