Abstract

An energy system transformation is mandatory to reach a climate-neutral energy system. Several challenges within this transformation process have to be overcome. Due to the increasing sector coupling and renewable energy power plants on a decentralised level, new challenges arise. Photovoltaic systems, heat pumps, and electromobility can provoke higher power flows at the low voltage grid level, which results in voltage issues and overloaded transformers or power lines. Consequently, curtailment of photovoltaic power is necessary, or load outages may occur. Battery storage systems provide a promising solution to counteract these challenges and enable the energy transition. The influence of three operating and three positioning strategies of home and community battery storage systems on voltage stability, transformer and line load and on-site supply for low-voltage grids have been investigated in a highly renewable and sector-coupled energy system. Power flow simulations with five representative synthetic low-voltage grids have been conducted. The results show that without further measures, the safe operation of the equipment cannot be guaranteed in the representative grids. However, home battery storage systems can reduce grid issues, curtailment and increase the self-consumption of photovoltaic energy. Using digitally interconnected battery storage systems achieve the best results, as it can serve both the self-consumption and the grid. Home and community battery storage system prove to be equally suitable.
