8 ESS in Demo4 ESS main characteristics Battery technology: Li-ion Max power: 1 MVA Energy capacity: 1 MWh Number of cycles: 2000 Efficiency: > 80% Grid4EU Project It will be installed a storage system (1 MVA 1 MWh) in a MV/LV substation that can be connected to several feeders. The goal is to study a new centralized/decentralized solution for voltage regulation and hosting capacity rising. In particular, thank to this particular installation, it will be possible to move the storage in different feeders depending of the results of an optimization procedure (ESS optimal location). 8

In particular, the ESS will be used to control energy exchange profiles between the HV/MV substations and the National Grid to make them more predictable (1h - 24h ahead).

11 ESS in MV/LV substation ESS in the Isernia Project Isernia Smart grid Integration of renewables Storage (1) Customer Engagement (demand response) (8.000) Electric Vehicles (5 Charging pole) The project born following a call of the Italian Regulator (AEEG). Inside the selected project, the Isernia project had the highest score in the innovation classification, because propose several promising solutions for a secure and reliable operation of the network and to increase the hosting capacity. The involved network is a MV busbar of the primary substation of Carpinone with 8000 LV customers, 26 MV customers (9 have renewable plants). 11
