1 A PROOF OF CONCEPT ON A IEEE BASED SMART METERING ARCHITECTURE WSPLC 2015, Klagenfurt Daniel Rohrmoser September 2015

2 AGENDA Smart Metering approach at Salzburg AG Proof of Concept: Metering based on IEEE Results and conclusion WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

3 SMART METERING APPROACH AT SALZBURG AG Smart Metering Target architecture developed in 2013 Main Targets 1. Open Standards for sustainable investments and vendor independence 2. Internet Protocol to separate communication and application 3. Security state of the art security techniques on multiple OSI layers 4. Powerline (PLC) in Last-Mile and usage of own telecominfrastructure in Second-Mile WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

4 SMART METERING POC Pilot project based on new PLC Standard IEEE Technology supplier Cisco, Itron Lab-Environment + 3 low voltage grids (~250 meters) Pre-defined Use Cases for operation Timeframe: June 2014 August project-phases Phase1: PLC in CENELEC A Band (9-95 khz) Phase 2: PLC in FCC Band ( kHz) WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

5 POC SCHEMA IP END-TO-END COMMUNICATION Head-End- System Fibre Transformer Router PLC Smart Smart Meter Smart Meter Meter Smart Meter IP WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

6 SECURITY-KONZEPT IM POC OSI L. 7 Application DLMS (LLS/HLS) End2End OSI L. 3 Network IPsec VPN OSI L. 2 Data Link IEEE 802.1X IEEE i PLC Network WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

7 RESULTS AND CONCLUSION OF PHASE 1 PLC in CENELEC A Band (9-95 khz) Performance of daily readouts ~90% successful (for 2 sites) 65% <6h 25% 6<12h not sufficient for Austrian requirements PLC problems at 3 rd site high noise level in CENELEC A Band caused by heating power plant 67% success in readouts WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

8 RESULTS AND CONCLUSION OF PHASE 1 insufficient information about channel capacity Layer 3 measurements planned with TU Dresden for phase 2 version of DLMS (Green Book 7.3) not optimized for lowbandwidth networks improvements in new version (GB 8.0, 07/2014): Multicast addressing support Long Term Application Association Access-Requests WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

9 RESULTS AND CONCLUSION OF PHASE 2 PLC in FCC Band ( kHz) + RF Mesh ( e/g in 2.4 GHz Band) Performance of readouts >98% for daily load-profile readout in <6h PLC worked well even for noise-affected site of phase 1 usage FCC Band showed performance improvement improvements in DLMS GB 8.0 result in good performance RF Mesh in 2.4 GHz band is useless in Austria due to the location of the meter in basements/cabinets WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

10 ADDITIONAL SUB-PROJECTS Long Term PLC Measurements (TU Graz) IP Performance Measurements (TU Dresden) 870 MHz RF Mesh survey in Salzburg WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

11 LONG TERM PLC MEASUREMENTS TU GRAZ Measurement campaign during 7 days at different low-voltage grids Frequency range: 50kHz to 2 MHz Impedance Noise Attenuation Conclusion: recommendation to use Frequency range >100 khz WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

12 IP PERFORMANCE MEASUREMENTS (TU DRESDEN) FCC Band used 25 PLC modems installed at low-voltage grid in city of Salzburg (residential area) in distribution boxes Measurement during 6 weeks + Datarates up to 55 kbps in field + reliable links with high modulations (8PSK/QPSK) over long distances (500m) + FCC brings flatter network (less hops) than CENELEC A network instability during high traffic load TCP not well supported because of packet loss problems identified and solutions will be provided in future releases WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

13 870 MHZ RF MESH SURVEY IN SALZBURG IEEE e/g MHz (400 khz channel spacing) 10 battery powered meters (to ease installation) placed in transformer station (outside) and at meter locations in customer buildings (basement, meter cabinets) modulation rate of LR (6.25kbps) and some locations at modulation rates from FSK (75kbps) to OFDM (200kbps) Could be a good extension to PLC to reach 100%! WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

14 870 MHZ RF MESH SURVEY IN SALZBURG WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept

15 CONCLUSION Recommendation for usage of Narrowband PLC in FCC Band rather than CENELEC A Band Improvements in DLMS GB 8.0 achieve good results in metering performance Well known security techniques (802.1x etc.) can be applied to PLC network IP Performance measurement showed that IEEE will be a adequate solution for smart metering implementation problems showed up accepted by vendor and solutions will be provided RF Mesh in 870 MHz band in combination with PLC could improve reachability of meters WSPLC 2015, Klagenfurt Daniel Rohrmoser, Sept
