1 The Telecommunication infrastructure for the smart grid Challenges for DSOs EURELECTRIC Survey intermediate results Koen Noyens, Advisor Networks Unit Brussels, 5 March

2 EURELECTRIC SURVEY TELECOMMUNICATION INFRASTRUCTURE FOR THE SMART GRID Motivation for the survey Identify the future communication needs of Smart Grid applications at different levels from substation level to the consumer level Categories Present Panorama Future applications and communication needs Network ownership versus leasing of services Network security and availability 2

3 Distribution system level Present panorama a typical DSO Wired Voice and Data services Optical Fibre, PDH & SDH, IP/MPLS Wireless Data Services Digital Radio Links supporting PDH and IP Substation level Wired Services Optical fiber LAN, copper cables, wired sensors, etc. Feeder level Wireless data services GPRS and VHF Radio Consumer level Wireless data services GSM/GPRS Wired data service PLC (trials) Field level Wireless Voice and Data Services GSM/GPRS, VHF Radio Source: EDPD 3

4 The communication infrastructure business critical applications Reliable, secure, high latency and high availability Lower level of latency and availability, but higher security requirements and greater bandwidth 4

5 Present communication technologies used by European DSOs for meter reading applications Source: EURELECTRIC 5

6 Some of the future data handling & management challenges Availability and performance of the new AMI communication infrastructure Retaining double meter value process chain during the AMI roll out (existing meter value collection, MDMS, rating, billing versus new AMI based processes) Standardisation of existing communication infrastructure for SCADA, current AMR, remote control systems, etc. Management of all the new collected data Prevention of viruses getting into the smart meter reading system Define an architecture using optical fibre that is black out resistant for the critical substations Protection against cyber attacks Ensure pay back of the new telecommunication infrastructure according to regulation 6

7 What are critical applications and/or services of the smart grid? Customer oriented Operational oriented 7

8 The impact of an electricity black out on the DSO services/applications (level of availability needed) Source: EURELECTRIC Scale: 1/ Low impact or only local impact: few customers, limited in time, no financial impact, etc.. 5/ Critical impact: important financial impact for the grid operator and/or industrial customers, impact on the environment, impact on the image of the grid operator, etc. 8

9 Impact of telecommunications default on the DSO services/applications (level of availability needed) Source: EURELECTRIC Scale: 1/ Low impact or only local impact: few customers, limited in time, no financial impact, etc.. 5/ Critical impact: important financial impact for the grid operator and/or industrial customers, impact on the environment, impact on the image of the grid operator, etc. 9

10 Do DSOs own and operate their own communication networks? In most of the respondent countries: YES, but often data network components (switches and routers) are managed by service providers (for operation and management reasons) Trials with: the CAPEX+OPEX solution for the next generation telecommunication infrastructure (IP/MPLS): network components are bought by the DSO (= CAPEX), but operated and managed by the telecom provider (OPEX) some Backup circuits (dark optical fibre or active circuits) requests to telecom providers The use of communications infrastructure of public operators and / or companies outside the electric company, has the disadvantage of limited availability at critical times, when the actual time / remote is essential to restore the normal situation. In addition there is no kind of priority in the services provided by public operators to electricity companies, so specific or structural bottlenecks in the network influence the efficiency of the systems 10
