IEEE-39-bus-power-system

A full-replica MATLAB/Simulink dynamic model of the IEEE 39-bus power system, including dynamic models of conventional generation and dynamic load profiles.

Simulink model

Transmission line parameters

The IEEE 39-bus does not specify any line lengths; therefore, we choose them to obtain a propagation speed just below the speed of light.

Loads profiles

We include two types of load profiles: constant and realistic. The constant load profiles are the original data of the IEEE 39-bus system. The realistic load profiles are active and reactive components inferred by time series data, adapted from a monitoring system based on Phasor Measurement Units (PMUs) installed in the 125-kV grid of the city of Lausanne, Switzerland. The resolution of the time series is 20 milliseconds and the profiles are voltage and frequency independent.

The real-time simulator

We use the Opal-RT real-time digital simulator OP5600, coupled with the eMEGAsim PowerGrid running on the RT-LAB real-time simulation platform. For installation, user guide and more information of the real-time simulator go here.

Software

The following software is required to run the model:

• MATLAB Version 8.5.1 (R2015aSP1)
• Simulink Version 8.5.1 (R2015aSP1)
• ARTEMIS Blockset Version 7.2.2.1206 (R2015a)
• RT-LAB Version v11.2.2.108 (R2015a.x), available here

  Note

  Before building the model, you need to add an S-function file (sfun_discreteVariableDelay.c) in the files section of your model. This file can be found under the following path C:\Program Files (x86)\MATLAB\R2015aSP1\toolbox\physmod\powersys\powersys. Add the file and choose ascii in Mode, S-Function in Category, and Before Compilation in the Transfer Time.
