Global parameters

You can define global parameter variables for use within calculations. These behave in the same way as global parameters for use in planning optimization.

Global parameters act as arbitrary optimizable variables that can be used within one or many calculations. You can use them to link different calculations together. A global parameter can be of two types:

• Time-Averaged: the global parameter has the same value across a period, and may have different values in other periods, unless constrained otherwise.

• Multi-Period: the global parameter can have different values at the beginning and end of the period. The closing value must be assigned as the result of a calculation, and is then carried forward as the opening value of the following period. You must define an opening value for the first period when creating the global parameter.
