Optimization of Battery Energy Storage System Operation in Distribution Grids

MSc thesis of Luca Argiolas

This research aims to evaluate the potential business case for BESS in Distribution Grids by integrating market application and additional DSO services. The feasibility of the solution is verified via a case study of a Photovoltaic - Fast Charging Station (PV-FCS). Three players are involved, namely PV-FCS owner, DSO, and BESS owner. The study shows that the BESS owner would have additional revenues, the DSO benefits from a reduced peak power and the possibility of deferring network investments and the PV-FCS owner from an overall 30% tariff reduction thanks to the peak shaving performed by the BESS.
