AB - Renewable energy generation is spreading apace worldwide, bringing integration challenges for distribution system operators. The focus of this study is to investigate the possible solutions to increase the hosting capacity of an actual low voltage (LV) feeder in Hungary. This pilot site already has significant photovoltaic (PV) generation, but more installations are expected in the near future. Simulations were carried out to compare the available technical options increasing the hosting capacity. Detailed on-site measurements were taken, which included the neutral line, to have a better understanding of the basic situation. It showed that the voltage is close to the limits with significant unbalance. Therefore, an unbalanced model was adopted with a new calculation method in order to incorporate the neutral line and the groundings. The simulations compared local PV inverter control, inline voltage regulator, tap-changing transformer and phase balancer and found the inline voltage regulator as the most effective and versatile solution for this case. A new device was developed and installed that implements an inline voltage regulator, optimized for local circumstances. Then, a longer series of measurements were taken which proved the effectiveness of the unit, showing that it can be a cost-effective grid development alternative to grid reinforcement. © 2023 IEEE.

Although there may be many challenges to the spread of renewables, such as their impact on the balance of the electricity system and on distribution networks. There are many pilot projects around Europe with the scope of flexibility. E.ON Hungary with their DSOs already participated in some H2020 projects which helped to conceive a comprehensive project approach in terms network hosting capacity. Flex.on is a Hungarian program led by E.ON distribution system operator subsidized by Hungarian government which conceptualized a comprehensive flexibility platform and eventually developed an IT system. The platform covers all DSO voltage levels with particular challenges. Several local flexibility platforms are under development in Europe, but there is no seen such wide scope in terms of voltage levels what Flex.on flexibility platform brought into focus. This ambitious goal meant that significant challenges had to be faced both in terms of research questions and IT development. This article outlines the scope of the programme, the system being developed and the challenges it poses. © The Institution of Engineering and Technology 2023.
