2 2 Agenda Introduction History & Motivation FttH activities in Constance Smart Metering in Constance Substation Automation Communication as a Key-Factor Smart-Street Lighting

3 Introduction Constance Birthplace of count Zeppelin Located in southern Germany / Swiss Border Lake of Constance Central Europe s third biggest lake Stadtwerke Konstanz - Municipal utility Constance: 3 - Roman origin - Population Two universities - Tourist area - Historical city centre - Natural reserve - EU-external frontier

4 Introduction Stadtwerke Konstanz Power, Gas and Water Supplier Energy Service City bus traffic Thermal Spa Ferry Boats and cruise vessels Distribution grid (110/20kV) Redundant supplier (Germany / Switzerland) 300 Substations / Power Meters Central SCADA System (NCC) 5MW Photovoltaic Power (No Wind power) Telecommunications city carrier (FTTH) 4 Submarine fibre optic cables

5 5 History and Motivation The world needs about 5 computers. (Th. Watson 1943) Computers in the future may weigh no more than 1,5 tons. (Th. Watson, Popular mechanics 1949) No one will need more than 637kb of memory for a personal computer. (Bill Gates, 1983)

6 6 Motivation for Fibre Optic Networks Nielsen s Law: Users' bandwidth grow by 50% per year Copper-based communications (xdsl) will soon reach capacity and bandwidth limits!

7 7 FttH Activities in Constance Fibre optic backbones since 1996 Originally used for substation automation only Poor data connection of constance until 2007 No Internet in the industrial area available until 2011 Submarine fibre optic cable in 2007 (30km) FTTH rollout for whole city area (10 years) Stadtwerke Konstanz: Carrier for Internet, Telephone, TV Key success factor for Internet of the Energy Two fibers per building reserved for Smart X

8 8 FttH Activities in Constance

9 9 Smart Metering Activities Various Field Tests of Smart Metering Systems Power Line, DSL, TETRA, GSM/UMTS, etc. Research Project since 2004 University of Constance (Computer Science Dept.) Development of a Universal Home Service Gateway (Hardware), IP-Based Development of a Software-System to manage meters (bidirectional) data collection and storage Web based customer front-end to visualize data Standard database-interfaces for third-party-systems Data encryption through standard VPN-technologies

11 Communication as a key factor Results of smart metering activities Low acceptance with customers (today) / No real benefit for consumers Establishment of communication links (bidirectional) is expensive But: Energy grids have to be highly automated (Smart Grids) Challenges for Smart X Automation of numerous Systems and levels, controlling various parameters SCADA System plays a central role (central control of all systems) Collection, storage and evaluation of data (Data Mining) Convergence of Energy- and Communication Networks 11 Bidirectional, fast, secure and reliable Communication based on Fibre Optic is essential for future proof automation purposes

12 12 Fibre to the Substation High Reliability Future Proof Fibre Optic Infrastructure Secure Networks Scalable Technology Broadband Smart Meters FttH

13 13 Substation Automation Transformer Substation FttH - POP Active industrial ethernet switches in combination with fibre optic networks are the basic infrastructure for intelligent energy networks (Smart Grid). They are also used to control FttH-concentratorstations (POP) Automation Fire Alarm Access Control Air-Conditioning UPS Metering Power Quality Internal Telephony Network Mgmt Access Ports etc. Ethernet Switch (Industrial)

14 14 Smart Street Lighting Research Project to reduce OPEX for Street Lighting Metering of energy consumption of Street Lights (per cluster) FttS in combination with industrial Ethernet switches Connection of SCADA System with the Smart Metering System Usage of Universal Home Gateways Number of street lamps in Constance: ca Average energy consumtion per lamp: ca. 100W Overall consumption: ca. 1MW Project-Goals: Automatic indication of defect lamps Cancellation of manual routine controls during daytime Transparent visualization of energy efficiency and consumption data (billing)

15 15 Smart Street Lighting Substation Installation IEC1107 (RS485) Fibre Optic Network SQL-Interface Web-Interface, Data visualization SCADA System Smart Meter System

16 Summary Smart Grid is strongly related to automation aspects Complete grid automation cannot be done within a few years First Step: Distibution Grid - Substation automation is crucial Fibre optical networks are necessary to provide reliable, fast and secure communication 16 FTTH-Projects can generate huge synergy Potentials
