Modified IEEE 33-Bus Distribution Network Dataset with Hourly Energy Community Demand and Distributed Energy Resources

This dataset provides the input data used for the case study of a modified IEEE 33-bus radial distribution network with energy communities and distributed energy resources. The network comprises 33 buses and 32 branches, with bus 1 acting as the slack bus and buses 2–33 representing 32 energy communities. The dataset includes the electrical network parameters, nodal peak demands, operational voltage and thermal limits, and a complete set of hourly active and reactive demand profiles covering a non-leap year (8760 hours). Hourly demand trajectories are complemented by synthetic and reproducible PV generation profiles for the 32 energy communities. The dataset also contains the location and capacity of existing PV and battery energy storage systems (BESS), together with the main physical and techno-economic parameters used to characterize candidate PV and BESS investments. The MATLAB data file includes, among others: IEEE 33-bus network and branch data; 8760-hour active and reactive demand profiles; 8760-hour PV capacity-factor and generation data; mapping of the 32 energy communities to network buses; existing PV and BESS locations and capacities; voltage and branch thermal limits; PV and BESS technical parameters; investment-cost and lifetime assumptions; and metadata required to reproduce the deterministic input dataset. The dataset is intended to support reproducibility and further research on probabilistic distribution-system planning, energy communities, distributed energy resources, and grid-security-oriented investment studies. The data are provided in MATLAB MAT-file format.
