Extension of the IEEE 39-bus Test Network for the Study of Fundamental Dynamics of Modern Power System

We provide the full-replica dynamic models of three versions of the IEEE 39-bus power systems, to be used as a benchmark for studying the fundamental dynamics of modern power systems in the presence of inverter-connected devices.

The up-to-date 4 models correspond to three configurations of the IEEE 39-bus power system with different amount of inertia:

• The original 10-synchronous machine system, noted as Config. I [topology]
• A low-inertia system, 4 synchronous machines are replaced by 4 type-III wind power plants, noted as Config. II [topology]
• Config. II implemented a Battery Energy Storage Systems (BESS) that integrated into the power grid through a Voltage Source Converter (VSC), noted as Config. II_BESS_VSC [topology]
• A very low-inertia system, 6 synchronous machines are replaced by 6 type-III wind power plants, noted as Config. III [topology]

Along with the provided dynamic models, we also upload a report where the dynamic models and the corresponding simulation results are presented in details.

Simulation notes

• It is recommend to use Phasor Measurement Unit ( PMU) to measure phasor, frequency and ROCOF. In another project CS-TFM PMU model, we provide the PMU models that relie on Compressive Sensing Taylor-Fourier Model (CS-TFM) approach
• It is worth to note that, due to the limitation of Syncrhonous Machine block in discrete system in MATLAB/Simulink, it is necessary to use a small parasitic resistive load, connected at the machine terminals, to avoid numerical oscillations. Details regarding how to use parasitic resistive load,see in Mathwork.

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 on 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
