Information

1. Purpose of model

The superstructure component provides a representation of a certain region in terms of consumption and production of power and gas. This representation is comprised of multiple elements that connect with the central electric and gas ports and either consume or generate gas or electrical power. Superstructures are to be used as arrays enclosed in superstructure portolio masks for maximum utilization.

See usage guide for more information.
