  1. Power Line Communication (PLC) an important part of a Smart Grid Amit Grauer VP Product Management Yitran Feb 2011

  2. Agenda • What is Smart Grid ? • Where does PLC fit in Smart Grid? • About PLC • About PLC Standard activities • Applications and Markets • About Yitran

  3. Smart Grid Applications AMI Applications Other Applications Business Intelligence Applications Automatic DR Applications Smart Grid Management & Control EMS/NMS/SGMS Distribution Network Control Home Appliance Control Demand Response Infrastructure AMI/AMR Smart Meters Smart Home Elements What is smart Grid?

  4. Why do we need a Smart Grid? • Reduce peak to average consumption from the Utility point of view • Reduce the power consumption during peak demand periods • Enable Utilities to get real time information regarding each device/Meter on the Grid • Enable adaptive tariff according to the consumption (TOU)

  5. Smart Grid Applications AMI Applications Other Applications Business Intelligence Applications Automatic DR Applications Smart Grid Management & Control EMS/NMS/SGMS Distribution Network Control Home Appliance Control Demand Response Infrastructure AMI/AMR Smart Meters Smart Home Elements Where PLC can fit?

  6. Utility Grid GPRS GPRS GPRS 1 1 1 2 2 2 3 3 3 PLC Network #1 PLC Network #2 PLC Network #N 220 200 300 GPRS CFE Sub Station Back Office

  7. LV Transformer PLC – GPRS Bridge 1 Concentrator GPRS 2 3 400 PLC Network PLC Remote 1. One Concentrator under the transformer 2. Up to 1000 Smart Meters 3. Each Meter can serve as a repeater PLC Remote

  8. Home Demand Response: Higher price indication, encourages consumers to reduce demand, thereby reduce the peak demand for electricity.

  9. PLC Communication The Channel: • High attenuation 60dB-90dB • High noise in the grid – white noise and color noise • Impedance modulation – correlated to 50/60Hz, loads in the home. PLC Modem • TDD – Time Division Duplexing • Operate between 9Khz-500Khz • Rates 5Kbps up to 500Kps • Modulation: Spread Spectrum, OFDM, SFSK • PLC Networking Layer – “Mesh”

  10. PLC: A no new wire technology • Using the existing Power Line infrastructure • Simple installation • PLC unit integrated in the unit • No need for additional components ( e.g. antenna ) • Automatic network creation • Cost effective • One chip solution including AFE • Application embedded in the PLC chip • Support - Remote software download ( maintenance) • Performance • More then 90dB dynamic range • Distance – can communicate over 1Km point to point • Designed for Command and Control • High reliability • Low power consumption

  11. Standards Activities • HomePlug CC • ITU G.hnem activity • IEEE P1901.2 activity • PRIME – Ibedrola initiative • G3 – Cooperate with EDF • Others
