power-system-expansion-planning

This code accompanies the paper Feedback enhancement of time series aggregation for power system expansion planning by Ruiqi Zhang, Ensieh Sharifnia, and Simon Tindemans, submitted at PSCC 2026.

In this project, a Transmission and Generation Expansion Planning model is formulated on Pyomo platform using Python, incorporating potential expansion options, including wind farms and transmission lines. One example is provided with IEEE RTS 24-bus network.

Quick start

1. analysis_NoStorage_withFeedback.ipynb and analysis_NoStorage_withNoFeedback.ipynb provide ready-to-run models.
2. comparison_feedback.ipynb and comparison_ts_and_op_error.ipynb provide the code for all plots in the paper.
