Demo 5 - Distribution Network Ancillary Services Data

This dataset contains the data underlying Figs. 5–10 of the conference paper Real World Provision of Ancillary Services by PV Energy Communities in Distribution Networks. The data support the field validation of voltage- and frequency-related ancillary services provided by five photovoltaic (PV) plants belonging to an energy community connected to a real 20 kV medium-voltage distribution network in Greece. The dataset includes measured and processed data from controlled field tests of decentralized droop-based ancillary-service functions implemented at PV-plant level. It covers the validation of the Limited Frequency Sensitive Mode–Overfrequency P(f) response with 8% droop, feeder-head measurements during the corresponding frequency-support test, validation of Q(P) and Q(V) reactive-power droop characteristics for the five PV plants, feeder-head measurements during an almost 24-hour Q(V) field test, and P(f) control scenarios affected by delayed-response and denial-of-service communication disturbances. The data include PV-plant-level and feeder-level quantities such as active power, reactive power, voltage measurements, frequency reference or emulated frequency profile, droop setpoints or theoretical characteristics, test timestamps, plant identifiers, and scenario labels where applicable. The dataset enables reproduction of the plots presented in Figs. 5–10 and supports further analysis of real-world ancillary-service provision by distributed PV plants in active distribution networks.
