  1. Overview of the Smart Grid Smarter Networks, Bristol, June  23-24th Guillaume d’Eyssautier, CEO

  2. What is the Smart Grid • The Smart Grid is a developing network of transmission lines, equipment, controls and new technologies working together to respond immediately to our 21st Century demand for electricity Consumer Engagement Smart Homes & Meters Distribution Intelligence Plug-In Electric Vehicles Renewable Energy Grid Operation Centers

  3. What Makes a Grid “Smart?” • digital technology that allows for two-way communication between the utility and its customers • sensing along the transmission lines • Like the Internet, the Smart Grid will consist of controls, computers, automation, and new technologies and equipment working together

  4. What does a Smart Grid do? • The Smart Grid represents an unprecedented opportunity to move the energy industry into a new era of reliability, availability, and efficiency that will contribute to our economic and environmental health. • The benefits associated with the Smart Grid include: • More efficient transmission of electricity • Quicker restoration of electricity after power disturbances • Reduced operations and management costs for utilities, and ultimately lower power costs for consumers. • Reduced peak demand, which will also help lower electricity rates • Increased integration of large-scale renewable energy systems • Better integration of customer-owner power generation systems, including renewable energy systems • Improved security

  5. Challenges for the implementation of a Smart Grid • Hundreds of million of devices will be connected • Power Generation • Metering devices • Sensing devices – Outage detection • Static Power consuming devices ( Industrial, Commercial, Consumer Appliances) • Mobile Power consuming devices ( EVs ) • Etc… • How do we manage all of this ?

  6. Need for a Smart Electricity Network • Integrated communication infrastructure that enables near real time , two-way exchanges of information and power • AMI that record and communicate detailed information about energy usage • Sensors and monitoring systems that check the flow of energy and performance of the network’s assets • Automatic controls that detect and repair network problems • Advanced infrastructure that improve network performance • IT systems with integrated applications and data analysis

  7. The need for Distributed Intelligence No real time feedback on usage Largely based on modelisation Not yet smart • The Smart Grid will allow the customer to participate in the market: • Benefit from dynamic pricing • Managed their power consumption • Resell micro generated power • Store and give back power ( PEVs) Need to be educated

  8. Smart Metering : what does each one need? Utilities need Low cost meter Technical performances; PLC, low power, reliability,… Open and multi-manufacturer solution Meter manufacturers need To fulfil technical and economical specifications Fast time to market Design based on open standards

  9. Communication Technology for the Smart Grid :Market trend • Numerous technologies are vying for the smart metering market • Narrow Band PLC is the best, most comprehensive, communication solutions PLC : narrow band ( 50KHz) Power Line Communication BPL : Broad band ( MHz ) Power Line communication

  10. Communication Technology for the Smart Grid- Wireless

  11. Communication Technology for the Smart Grid- Wireless : ZigBee prevails

  12. Communication Technology for the Smart Grid - Wireless : Zigbee • Zigbee support 3 frequencies, the worldwide is 2.4Ghz which have a big attenuation with the concrete walls and high humidity environments. • Big attenuation, means big number or repetitions and hops. Decreasing a lot the theoretical data rate • . 2.4 GHz ISM Worldwide 250 kbps 16 868 MHz Europe 20 kbps 1 ISM Americas 40 kbps 10 915 MHz 2 MHz Channel 0 868MHz / 915MHz PHY Channels 1-10 868.3 MHz 902 MHz 928 MHz 5 MHz Channels 11-26 2.4GHz PHY 2.4 GHz 2.4835 GHz

  13. Communication Technology for the Smart Grid - Wireless : Zigbee Red Areas indicate where communication is not possible 10m 20m 10m Test in building made of walls reinforced with iron, Bricks walls and Plasterboard walls. 29m ZigBee Board 9m

  14. Communication Technology for the Smart Grid PLC vs Zigbee • Zigbee was designed for in-home applications starting from a start type network for small number of nodes • to create a big network it requires to add coordinators and routers which are power consuming. • PLC support bigger network with less cost. PLC network is created with the structure of electrical cable and support a higher number of nodes without extra cost and penalties on the data rate and much less power • . PAN coordinator Router Zigbee Network End Node

  15. Communication Technology for the Smart Grid PLC vs Zigbee • PLC support bigger network with less cost. PLC network is created with the structure of actual electrical cable and support a higher number of nodes without extra cost and penalties on the data rate and much less power Base Node transmits Beacons (BPDU): BC0 Switch transmits its own Beacon (BPDU): BC1 T=(0,1) T=(0,3) T=(0,4) T=(0,2) S=(1,0) T=(0,3) S=(2,0) T=(0,4) BC4 transmitted by S(2,0) T=(1,1) T=(1,2) T=(2,1)

  16. Communication Technology for the Smart Grid :Market deployment Top European Utilities

  17. C ompany Facts ADD Semiconductor (Advanced Digital Design S.A.) established in 2001, started operation in 2007 Spin-out of the University of Zaragoza 45 employees, 30 dedicated to Research & Development Offices in SPAIN, USA, CHINA, INDIA • Provider of the world’s best, low cost and highly efficient, Power Line Communications (PLC) solution for smart grid and lighting applications consisting of chipsets, modules and software stacks

  18. ADD Focuses on Metering and Control • System on Chip (SoC) PLC for low and medium voltage electric grid transmission medium • Low cost solution for Smart Metering communication • Low power PLC chips for Lighting, Solar PV and Home & Industrial Automation • Full Digital Process using patent pending DSP technology to implement analog functions on standard low-cost digital process gives ADD SoCshigh efficiency at a very low power • All ADD designs are based on standard, open and cost-free protocols • ADD is able to develop on demand proprietary SoC solutions for specific applications • Current solutions are based on 180 nm technology, but new chips are designed in 90nm

  19. Applicable Markets • ADD’s PLC solution is applicable to numerous Smart Grid markets • Smart Metering • Multi-modulations and protocols solutions • Founding member of the latest communication standard • Lighting Control • Street and Industrial lighting • Home lighting • Solar PV & Wind Farm Installations • Home & Industrial Automation • With dedicated h/w and s/w platforms for consumers
