Synthetic Electric Grid for Ghana

This document presents a synthetic power grid test case developed for Ghana, West Africa, which can be utilized for power systems studies, algorithmic benchmarking, regional research, and educational purposes. Using publicly available data and methods from prior literature, this synthetic grid provides a "realistic but not real" test case that can be utilized for various applications.

This third version is an update of earlier versions with new features to more accurately reflect the Ghanaian transmission network. We include new substations and transmission lines completed in recent years. We also include shunts on select buses to make the model AC-feasible. Finally, in this latest version, we provide the geographical coordinates (longitude and latitude) of all buses in the network.
