Concepts

• Slots and the horizon. The engine prices time in slots (10 minutes by default) over a horizon (48 hours by default), in UTC.
• Series and forecasts. Every input other than the plant's setup is a time series: a value holds until the next sample, and a forecast input is the series of its issues. The engine reads each as it stood at a moment.
• Inputs. Each input's meaning, its name on every surface, and which command needs which.
• Units. A series carries its unit; the engine works in kW, kWh, a fraction for the SOC, and the prices' currency per kWh, whatever that currency is.
• The plant model. How the plant behaves, behind a port: it projects the flows, and the price rule reads them.
• Outputs. What a valuation gives per slot: the marginal cost, the regime, the surplus, the certainties, the values by source and the supply stack.

Terms of the trade (SOC, DC bus, hybrid inverter, ...) are in the glossary.
