MV/LV Transformer Station Load Measurements — Slovenian pilot site network (STREAM Project, 2025)

This dataset contains active power (P) and reactive power (Q) measurements recorded at MV/LV (20/0.4 kV) transformer stations in the Ajdovščina distribution network in western Slovenia. The measurements were collected as part of the STREAM project (Horizon Europe, Grant Agreement No. 101069681). The dataset covers the year 2025 at 15-minute resolution. All timestamps are in UTC (UTC+0). Transformer identities are anonymised (TR1, TR2, …). A separate dataset provides the corresponding technical parameters for each transformer (rated power, impedance characteristics, and losses).
