Towards cooperative ESS for distribution systems with high penetration of RES and EV the Storage4Grid vision

Storage4Grid (S4G) is a 36-months project funded by the European Commission under the call LCE-01-2016, area 1 (Storage). S4G proposes an innovative holistic methodology for modelling, planning, integrating, operating and evaluating distributed Energy Storage Systems (ESS) including storage at user premises and storage at substation level, Electrical Vehicles (EV), innovative energy metering and energy routing technologies. This paper presents a systematic strategy used by S4G to generate the use cases for two scenarios related to two test sites: in Bolzano focused on cooperative EV charging and in Fur addressing the impact of user and grid side storage coordination to the medium and low voltage distribution network. The paper summarizes the S4G vision, solutions, and approaches for evolving the cooperative and coordinated ESS scenarios into use-cases and related requirements.
