This repository contains startup material for dynamic simulation studies with PyRAMSES on a 5-bus system. The material is designed for the Control and Operation of Electric Power Systems (EEN452) course at Cyprus University of Technology.

The assignment focuses on understanding generator and controller behavior during disturbances, and on interpreting dynamic responses (frequency, voltage, rotor angle, and power). The test system includes:

• One synchronous generator with detailed machine, governor, and AVR models
• Composite load behavior (impedance and motors)
• External grid representation for disturbance studies
• Multiple operating points and disturbance scenarios

This material is part of the EEN452 course taught by Dr. Petros Aristidou at the Sustainable Power Systems Lab.

The full assignment brief is provided in:

• assignment.pdf

According to the assignment document, students must submit:

• A report (PDF) addressing all requested case-study questions, or equivalent answers in notebook Markdown cells
• The working notebook implementation (.ipynb) and all required input files

This assignment contributes 10% of the final grade. Late submissions are penalized according to the assignment rules.

• Transient Angle.ipynb: Example notebook for transient angle studies
• Case 2.ipynb: Example notebook implementation for Assignment Case 2
• dyn.dat: Dynamic model data
• lf1.dat, lf1solv.dat: Operating point 1 load-flow and solved state
• lf2.dat, lf2solv.dat: Operating point 2 load-flow and solved state
• obs.dat: Observable definitions for post-processing
• solveroptions.dat: Solver and simulation options
• nothing.dst: Empty disturbance file
• assignment.pdf: Official assignment handout

The assignment defines seven case studies (Cases 1-7), including:

• Set-point changes (active power and voltage)
• External system voltage dips
• Fault-and-clear events on line 1-3
• Line tripping scenarios
• Analysis of controllers (governor, AVR, PSS) and load recovery behavior

Use the notebooks as starting points and extend/adapt them to implement all required cases from assignment.pdf.

• Access to the course JupyterHub platform, or local JupyterLab
• PyRAMSES installed and available in the notebook environment
• Basic familiarity with Python and power system dynamics

pip install matplotlib scipy numpy mkl jupyter ipython pyramses

1. Open this folder in JupyterHub or JupyterLab.
2. Start with Transient Angle.ipynb or Case 2.ipynb.
3. Run cells sequentially.
4. Modify operating point files and disturbances to implement each assignment case.
5. Plot and comment on the requested observables.

• PyRAMSES documentation
• EEN452 course page
• JupyterHub 5-bus workspace
