PyPSA-GB: An open-source model of Great Britain’s power system for simulating future energy scenarios

This paper presents PyPSA-GB, a dataset and model of Great Britain’s (GB) power system encompassing historical years and the future energy scenarios developed by National Grid. It is the first fully open-source model implementation of the future GB power system with high spatial and temporal resolution, and data for future years up to 2050. Two power dispatch formulations can be optimised: (i) single bus unit commitment problem, and (ii) network constrained linear optimal power flow. The model is showcased through an example analysis of quantifying future wind curtailment in Scotland. PyPSA-GB provides an open-source basis for GB operational and planning studies, e.g., sector coupling and flexibility options. •Open-source model implementation of the future GB power system.•Showcase of quantification of future wind curtailment in Scotland in 2035.•Reusable for future development and application by other energy system modellers.•Future applicability for whole system, thermal energy storage, locational pricing.
