Grid model inspired to the IEEE 34 Node test feeder

Information

This model represents a grid inspired by the IEEE 34 node test feeder. In this example, the cable types and lengths have been modified in order to represent a typical distribution feeder.

The following three type of cables are in the grid: AL120, AL70, and Al35.

Simple model of a grid with 2 nodes and 1 link for medium voltage

Information

This model represents a simple grid with two nodes and a single link between them. This model differs from Buildings.Electrical.Transmission.Grids.TestGrid2Nodes because it defines a medium voltage cable instead of a low voltage cable.

The picture below describes the grid topology.
