Unmet Load
Unmet Load components are special "last resort" generators with very high penalty costs. They allow the optimization to solve even when demand cannot be fully met, providing diagnostic information about system capacity shortfalls.
An unmet load component is connected to exactly one bus. If it dispatches in your results, this indicates insufficient generation or transmission capacity to meet demand at that location.
Diagnostic Component
Unmet Load should only dispatch when the system genuinely cannot meet demand. If you see unmet load in results, it typically indicates a modeling issue or genuine capacity shortage that needs attention.
Attributes
Unmet Load components have two types of attributes:
