Grid Operations & Market Clearing Architecture

A single-page, macro-to-micro walkthrough of the operating day: day-ahead SCUC, intraday reliability repair, AC state estimation, and 5-minute SCED with LMP separation under N-1 congestion.

1 · Pick a stageUse the timeline to move from market clearing to real-time operations.

2 · Read the summaryThe right rail explains what the operator or market engine is deciding.

3 · Stress demandDrag the dispatch stack line to see marginal units and congestion react.

4 · Inspect constraintsHover the heatmap or network to connect commitment, flow, and LMPs.

Day-Ahead SCUC

The day-ahead market forms a full-horizon network-constrained commitment plan, co-optimizing energy, reserves, ramping, startup/shutdown costs, and minimum up/down logic over a linearized transmission model; AC feasibility is validated downstream by EMS.

Interactive supply vs. demand dispatch stack

Drag the demand line, or focus the chart and use the up and down arrow keys, to stress SCED. The marginal segment updates the energy price; congestion adders appear when the N-1 limit binds.

Model boundary: this is an educational SCED/LMP visualization. It preserves the market/reliability split, but simplifies production-grade settlement, losses, reserve zones, and topology processing.
