4 wind farms are added to the original IEEE-39-bus power system

IEEE-39-bus-4WG-power-system

A full-replica MATLAB/Simulink dynamic model of the adapted IEEE 39-bus power system, including dynamic models of 10 synchrnonous generations, 4 type-3 wind farms, 19 dynamic loads and M-class CS-TFM estimators. All the required files are included in model.zip

New features

  • 4 type-3 wind farms are added to bus 2, 8, 11, and 21.
  • The EPRI LOADSYN model has been adopted as dynamic load model
  • M-class cs-TFM PMUs are installed on each load bus for local under frequency load shedding (UFLS)

Simulation Model

The main MATLAB/Simulink model.

Initialization Files

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

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.

Wind power profiles

The wind power profiles for the 4 wind farms are at 1 second resolution and obtained by resampling the measurements at 1 minute resolution from ERCOT (Electric Reliability Council of Texas).

Initialization files for M-class cs-TFM PMUs

This file is used to initialize parameters for the M-class cs-TFM PMU models implemented on the loads.

Initialization for dynamic simulation

This file provides a guide of initialization for dynamic simulations.

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.
