The quantitative assessment of effects and benefits of battery storage systems in households with photovoltaic (PV) generators and the effects on distribution and transmission grids need to be identified and analyzed for future energy supply systems. As analysis tool a MATLAB-based model of a distribution grid with multiple storage systems has been implemented. The model is applicable for a wide range of different battery storage systems, various PV-system sizes and diverse grid structures. Different battery management strategies such as fixed power limitation, charging interval timer with regard to typical solar radiation profiles, maximizing self-consumption and maximizing the benefit for the grid have been implemented and analyzed. If the storage is managed properly a relief for the grid can be achieved while at the same time the self-consumption can be retained at nearly the same level as a management strategy purely maximizing the self-consumption.
