This presents the dataset associated with the work "A Single-period OPF-based Strategy to Manage Distributed Energy Resources with Intertemporal Constraints in Low-voltage Grids". The work aims to investigate the voltage and thermal issues with the Dutch LV grid under the energy transition, and propose a new strategy to manage these issues through the use of distributed energy resources located at residential premises. The dataset includes base load, EV load, and heat pump load for both a summer and a winter cases, as well as a network topology dataset. The base load, heat pump load, and network topology data are from a Dutch DSO, while the EV load dataset is obtained from a Monto Carlo simulation process. The PV data in the study are obtained from Solcast.
