Dataset for: Impact of distributed BESS controlled by optimization-based HEMS on the voltage profiles in high PV-saturated LV networks This repository contains the dataset used for the simulations and analyses presented in the research article: "Impact of distributed battery energy storage controlled by optimization-based home energy management systems implementing various objective functions on the voltage profiles in the low-voltage network with a high saturation of prosumer photovoltaic micro-installations" Authors of the Article and Dataset Roman Korab (Department of Power Systems and Control, Faculty of Electrical Engineering, Silesian University of Technology, Gliwice, Poland) - Corresponding Author Marcin Połomski (Department of Algorithmics and Software, Faculty of Automatic Control, Electronics and Computer Science, Silesian University of Technology, Gliwice, Poland) Marcin Smołka (Joint Doctoral School, Silesian University of Technology, Gliwice, Poland) Tomasz Naczyński (Joint Doctoral School, Silesian University of Technology, Gliwice, Poland) Abstract of the Article Prosumer photovoltaic (PV) micro-installations change the operating conditions of low-voltage (LV) networks. When these networks are highly saturated with PV sources, some disruptions in their operation may occur periodically. In particular, long-term overvoltages are a frequent phenomenon, the most noticeable effect of which is the shutdown of PV sources. The simulation results showed that long-term overvoltages could affect more than a third of the customers supplied from a real LV rural network and last up to 383 hours per year. As a result, the yearly generation of the PV source can be reduced by up to 25.6%. The method of overvoltage mitigation analyzed in this article consists of changing the unfavorable power balance using distributed battery energy storage systems (BESSs). However, the effectiveness of this voltage control method depends on the adopted control strategy for the BESSs. In this article, distributed BESSs are assumed to be controlled by individual, optimization-based home energy management systems (HEMSs). Using a model of a real LV rural network, the impact of BESSs operating according to the schedules resulting from two objective functions of HEMSs (i.e., energy cost minimization and maximization of prosumer financial neutrality) are compared. Better results are achieved when BESSs are operated according to profiles that maximize the financial neutrality of prosumers. In this case, the maximum duration of long-term overvoltages is reduced from 383 to 231 hours per year, compared with 251 hours when the BESSs are controlled in a way that minimizes energy costs, while the yearly reduction in PV generation is 16.1% and 17.9%, respectively. Dataset Description This dataset comprises simulation results derived from a model of an actual low-voltage (LV) rural distribution network. It encompasses various scenarios of Battery Energy Storage System (BESS) operation, with data organized into daily and yearly simulation outputs. Note on Network Model: The detailed model of the LV distribution network used for these simulations is proprietary and not publicly available due to confidentiality agreements with the network operator. However, the input data profiles provided in the subfolders allow for the replication of load, PV generation, and BESS dispatch conditions.
