  • 11. Uso: PubblicoFunctions of the ESS in the distribution grid The Enel Distribuzione experimentations POI G4EU Ventotene Isernia 11Christian Noce
  • 12. Uso: Pubblico The Isernia smart grid project ESS in the MV/lv substation Isernia “Smart grid” Customer Engagement Integration of Electric Vehicles Storage (1) (demand response) renewables (5 Charging pole) (8.000)The project born following a call of the Italian Regulator(AEEG).Inside the selected project, the Isernia project had thehighest score in the innovation classification, becausepropose several promising solutions for a secure andreliable operation of the network and to increase thehosting capacity.The involved network is a MV busbar of the primarysubstation of Carpinone with 8000 LV customers, 26 MVcustomers (9 have renewable plants). 12 Christian Noce
  • 13. Uso: Pubblico ESS in MV/LV substation ESS in the Isernia Project Isernia Project The local control system will use the ESS to optimize both the active and reactive power exchanges between the node and the feeder; alongside the mitigation of the PV emission and EV recharging impact on the network, a real optimization of both local and global parameters will be taken into account by the integration with the Enel’s DistributionESS main characteristics Management System.Battery technology: Li-ion The installation of the ESS has been carriedMax power: 1 MVA out.Energy capacity: 500 kWhNumber of cycles: 2000Efficiency: 85%Installation area: 90 m2 13 Christian Noce
  • 14. Uso: Pubblico ESS in MV/LV substation ESS in the G4EU Project G4EU Project The Italian Demo Region of the European project G4EU is located in the Italian region Emilia Romagna. Enel, that lead this demo, will install a storage system (1 MVA – 1 MWh) in a MV/LV substation that can be connected to several feeders.ESS main characteristics The goal is to study a new centralized/decentralized solution for voltageBattery technology: Elettrochemical regulation and hosting capacity rising. InMax power: 1 MVA particular, thank to this particular installation,Energy capacity: 1 MWh it will be possible to “move” the storage inNumber of cycles: 2000 different feeders depending of the results of an optimization procedure (ESS optimalEfficiency: > 80% location).The goal of the GRID4EU project is to carry on demonstration pilots of Smart Grids solutions ona large scale basis. The project involves 27 partners in 12 EU countries; it is coordinated byERDF, the main French distribution company, and has its technical management belonging toEnel. The initiative will implement 6 demonstration projects in 6 EU countries (Italy, France,Germany, Sweden, Spain and Czech Republic), to be integrated into a single one. 14 Christian Noce
  • 15. Uso: Pubblico ESS in a microgrid ESS in the Ventotene Project Ventotene Project In Ventotene island an ESS will be installed by Enel Produzione for the renewable energy integration and the network stabilization. The network is a MV microgrid not connected to the Italian transmission/distribution system, where the electrical energy is supplied by a diesel generator and several other dispersedESS main characteristics generators.Battery technology: Li-ion The goal is to increase the hosting capacity ofMax power: 1 MVA the grid allowing the connection of newEnergy capacity: 500 kWh renewable sources. Moreover, the installationNumber of cycles: 2500 of the storage system will optimize the loadEfficiency: 85% curve of the diesel generator (enabling costsVentotene scenario reduction) and stabilize the network.Load: 0.15 MVA ÷ 1.15 MVANot-renewable installed power: 4 Diesel generators for total 2.7 MVARenewable installed power and new request: 76 kW today, new request for 74 kWMin Load = Max renewable generation → NO hosting capacity without ESS 15 Christian Noce
  • 16. Uso: Pubblico ESS in HV/MV substations ESS in the POI Project POI Project Three ESS will be used to reduce the variability of the power flow in the parts of the network with high penetration of RES, alleviating fast power flow variations in case of wind gusts or passage of clouds. In particular, the ESS will be used to control energy exchange profiles between the HV/MV substations and the National Grid to makeESS main characteristics them more predictable (1h - 24h ahead).Battery technology: Li-ion DirilloMax power: 2 MVA CampiEnergy capacity: 1 MWh (2), 2 MWh (1) salentinaNumber of cycles: 2000 ÷ 4000 ChiaravalleEfficiency: 85%Max installation area: 200 m2/MWh 16 Christian Noce

  • 19. Uso: PubblicoStorage introduction in Enel distribution network Concusions The impact of Renewable Energy Source (RES) on Italian distribution network is very high The costs for the systems (regulations and reserves) increase and ESS can be a key factor to reduce them but, today, incentives are necessary to develop ESS solutions Enel Distribuzione have around 3400 HV/MV transformers in Italy that feed the 85% of the Italian distribution network Enel Distribuzione have 6 pilot projects to test the ESS functions for the distribution network ESS connected to HV/MV substation can contribute to reduce the costs for power reserve for the electrical system In case of positive pilots Enel Distribuzione identified 46 further installations in the next years 19Christian Noce
