Every site is described by a common entity model. This model feeds both the deterministic EMS and the AI Kernel, so explanations always trace back to the same audited records that control relies on.
| Entity | Description |
|---|---|
| Site | Top-level facility: location, utility territory, interconnection program, tariff association. |
| Asset | Generic equipment record with type, ratings, vendor, firmware, and lifecycle state. |
| PCS | Power conversion system: ratings, control map, limit set, command interface. |
| BMS | Battery management system: permissives, limits, rack inventory, fault codes. |
| Battery Rack | Rack-level capacity, SOC, temperature, and health attributes. |
| Meter | Revenue and submeter points: location in SLD, CT/PT configuration, data quality state. |
| Relay | Protection relay: role, status points, trip/permissive signals, settings reference (settings themselves are engineering-controlled). |
| Breaker | Switching device with 52a/52b feedback, close authority mapping, and operation history. |
| Alarm | Classified alarm instance: source, severity, state, acknowledgement trail. |
| Event | Timestamped operational event: mode changes, commands, trips, grid events, user actions. |
| Dispatch Plan | Approved plan: intervals, setpoints, constraints checked, approval identity. |
| Dispatch Result | Realized operation per interval: delivered power, deviations, derates, reasons. |
| Tariff / Price Signal | Rate structures and market/price signals used for value calculation. |
| Load Forecast | Site load predictions with horizon, source model, and accuracy tracking. |
| Weather Forecast | Weather inputs relevant to load, PV (if present), and thermal constraints. |
| Battery Health Snapshot | Periodic health record: capacity estimate, resistance trends, cycle statistics, anomalies. |
