A tab for the Constraints grid appears in the data type selector panel at the top of the display area for Scenarios and Forecasts. The grid shows all constraints that are binding in the optimal dispatch solve, and provides information for understanding what is driving price and dispatch in any particular solve. The column data is described in the following table.

Column Description
Constraint Type
The type of constraint that is binding:
  • Circuit Equation - an equation constraint
  • Region Risk Fast (or Sustained) - risk in a reserves region set by an AC (generator) risk
  • Import Risk Fast (or Sustained) - risk in a reserves region set by a DC (HVDC) risk
  • Unit risk -
  • Max Gen Fast (or Sustained) - a unit providing reserves is constrained such that dispatched reserves plus dispatched generation equals maximum output in MW
  • Max Gen Slope Fast (or Sustained) - a unit providing reserves is constrained such that dispatched reserves is a fixed factor of dispatched generation in MW
