Transmission corridors

The concept of transmission corridors is used to provide a common umbrella for individual transmission options between areas. They do not have any direct application within the mathematical description, but simplify the overall framework structure.

Introduced type and its fields

EnergyModelsGeography introduces only a single concrete type. Hence, it is not possible to provide any additional subtype to change the behavior.

The fields of the type are given as:

from::Area and to::Area:
The field from denotes the area in which the corridor is originating while field to denotes the area to which resources are transported in the corridor. This is especially important for unidirectional transmission. It does not have a meaning in the case of bidirectional transmission.
modes::Vector{<:Transmission}:
It is in general possible to include an arbitray number of transmission modes within a single corridor. As an example, you could consider both AC and DC power flow between area 1 and area 2.

Directional flow

The design of EnergyModelsGeography differentiates between bi and unidirectional flow. While bidirectional flow is the standard for power transmission, it is not necessarily possible to utilize it for pipeline transport. Hence, it is important to be certain about the from and to area with respect to the flow direction.
