Step 1: Create the Electric Network Model

Create an electric network model using the SAInt’s extensive object library. The model has the following features:

High and low voltage grid (12.47 kV / 480 V) at 60 Hz frequency
Topology: 13 nodes, 12 branches
Externals: demands, PV generators, and a generic generator representing the upstream high-voltage grid

1. Create a new project and add your network

Start by creating a new empty project. Save it with the name acpf_intermediate in its own directory. Review the units of measurement for the project, as the tutorial uses units based on the International System. Select the euro as the currency unit.

The network layout is shown in Figure 1. The network is comprised of 12 electric branches, out of which one is a transformer. Regarding the externals, there are twelve demand points, one generic generator, and five solar generators.

You can build the network yourself by referring to Figure 1 and using the details provided below, or you can make a copy of the system using the files provided in the sub-folder .\Electricity Networks\Intermediate Tutorial 1 of the folder Tutorials in the directory (C:\Users\...\Documents\encoord\SAInt-v3\Projects).

Figure 1. Diagram of the electric network used in the tutorial. The electric line lengths are not to scale.

The following tables provide the details needed to complete the network. Default values are assumed for all properties not in the tables.

3. Define properties for the externals

This network has three types of externals - electric demands, generic generators, and solar generators. See Figure 2 and Figure 3 for the location of these externals. Their properties are listed in the following tables.
