Buildings.Electrical.Transmission.Grids
Package that contains different types of grids
Information
This package contains different types of grids that can be used to represent electrical networks. The topology of the network is specified by
- the number of nodes,
- the number of links,
- the length of links, and
- the connection between links and nodes.

Buildings.Electrical.Transmission.Grids.IEEE_34_AL120
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.

Modelica definition
Buildings.Electrical.Transmission.Grids.TestGrid2NodesMedium
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.
