Period definitions within classical multi-period models

When new periods are added in a multi-period model, a new embedded plant case representation is created. These can be modified to define the per-period case configuration.

A base single-plant single-period model always has a master case, and usually many subcases used for scenario analysis:

A multi-period model is initially based on a single period. When this is created, a master topology is created with a single period spanning the entire planning horizon:

Adding new periods to the model creates new embedded cases. Each of these embedded cases represents the configuration for that period. Scenario analysis is performed using subcases and overriding embedded case settings within the subcase:
