4 A2A Reti Elettriche SpA A2A is a DSO which operates in the cities of Milan, Brescia and in 46 other municipalities in the northern part of Italy. A2A s grid is spread across both highly dense urban areas as well as extraurban, lacustrine and mountainous environments which therefore present diverse characteristics and issues.

8 SubstationAutomationSystem Protection relays are used to protect assets in primary substation in case a fault occurs. e.gopeningthemainbreakerofthemvline HV/MV and MV/MV substations % 100 Today SAS are based on proprietary standards. Goal is to progressively adopt IEC Primary substation in Brescia This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 8

9 SubstationMonitoringSystem Provides further electrical information e.g. the actual load of MV/LV transformer(a) and environmental parameters, e.g. room temperature(b) MV/LV substations % 50 GoalistocoverallMV/LVsubstions a Snapshot of the SMS User Interface This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 9 b

12 Today s overallpicture A2A s grid already has a good level of technology penetration, but from an application stand point, those systems are: Centralized: field devices transfer data to the center only, i.e. there is no processing occurring at substation level with some exceptions for SAS Vertical: central applications do not exchange information amongst themselves natively, making the workflow management not efficient This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 12

13 Today s overallpicture Even though PSs are already connected via high performance FO connection from a communication point of view: In SSs, each system uses a dedicated GSM/GPRS apparatus which causes low efficiency and unnecessary operating costs Device SIM/modem LVC 8720 SMS RTU 3726 SCADA RTU Total number of GSM/GPRS equipments There s a need to re-design the ICT infrastructure A2A selected some research projects to evaluate possible alternatives This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 13

15 Project Summary INTEGRIS: INTelligent Electrical GRId Sensor communications THEME: ICT-Energy Grant no The goal of the INTEGRIS project is the design and the test of an ICT architecture enabling the Smart Grids that is: 1. heterogeneous, i.e. integrating multiple communication technologies (broadband power line BPL, wireless), 2. distributed, i.e. enabling the distribution of intelligence across the network, 3. open, i.e. underpinned by non-proprietary standards (e.g. IEC 61850, IEC 62056, SNMP ) This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 15

17 WhyHeterogeneous? There is no one single communication technology that possesses the right balance between performance and total cost (including operational ones). In fact a pervasive FO cabling is costly and requires long deployment time. The solution envisioned is therefore a mix: FO where already present or easy to install BPL over MV cables HR wireless (Wi-Fi) to add redundancy BPL over LV for the next generation of metering applications This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 17

18 WhyStandard? Standardization is extremely relevant for exploitation. INTEGRIS aims at extending the IEC standard beyond PS. Regarding smart meters DLMS/COSEM has been chosen. At SS level, a DLMS gatewayis need to merge data from different domains This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 18

19 Whydistribution? Information is growing exponentially. Grid management has to evolve from the present centralized model to a distributed model.

20 Tomorrow s overallpicture All those goals are achieved by equipping substations with INTEGRIS Device IDEV which integrates: Communication functionalities Protocol management(including security) Electrical algorithms This information was prepared by A2A and it is not to be relied on by any 3rd party without A2A s prior written consent. 20

22 Conclusions A2A has set a road map both for the short-term and the medium-term innovation. To make this vision real, research and pilot projects are a fundamental step. INTEGRIS is one of the most important piece of this puzzle,butisnottheonlyone.
