Potential Impacts of Demand-side Battery Storage on Distribution Networks with PV Penetration

In recent years, the use of energy storage systems to provide flexibility to renewable technologies has been identified as a key point to increase the effectiveness of clean technologies and reduce greenhouse gas emissions. In particular, the introduction of energy storage systems with batteries to supply consumers with self-consumption photovoltaic installations has proven to be a viable solution that can present additional benefits. One of these additional benefits can be a positive effect on the distribution network. In this paper, we analyze the potential impacts on the demand side that the integration of battery systems would have on distribution networks with photovoltaic penetration, specifically, the ability to perform peak shaving through battery systems is considered. To validate the potential of the battery system, a distribution system was simulated with real data, and a control strategy was also used to perform the peak shaving task. The results of the simulations indicate that the integration of battery systems can considerably improve peak load reduction by up to 0.2 MW in each phase on the distribution system.
