The Prescient Simulation Cycle

Note

This was taken from a previous write-up and needs to be revisited.

Prescient simulates the operation of the network throughout a study horizon, finding the set of operational choices that satisfy demand at the lowest possible cost.

Prescient loops through two repeating phases, the reliability unit commitment (RUC) phase and the security constrained economic dispatch (SCED) phase. The RUC phase determines which dispatchable generators will be active in upcoming operational time periods. For each operational period within a RUC cycle, the SCED phase selects the dispatch level of each committed thermal generator.

The RUC phase occurs one or more times per day. Each time the RUC phase occurs, Prescient generates a unit commitment schedule that indicates which generators will be brought online or taken offline within the RUC’s time horizon. The SCED phase occurs one or more times per hour. Each SCED selects a thermal dispatch level for each committed generator.

The RUC Phase

More detailed description of the RUC…

The RUC phase occurs one or more times per day. Each time the RUC phase occurs, Prescient generates a unit commitment schedule that indicates which generators will be brought online or taken offline within the RUC’s time horizon. The RUC schedule may begin immediately, or it may begin a number of hours after the RUC is generated.

The SCED Phase

More detailed description of the SCED, including a high level description of the optimization problem being solved, and possibly a conversational description of some things that can be tweaked (such as how often a SCED runs).

Future Values in SCEDs
