Final Sunseed Workshop Presentation

  1. 1. Smart Metering System for Microgrids Mehdi Savaghebi, Yajuan Guan, and Josep M. Guerrero Dept. Energy Technology, Aalborg University, Denmark
  2. 2. Outline  Introduction  Smart Metering System in AAU Intelligent MG Lab  EUDP Sino-Danish Project  Future Works 2
  3. 3. 3 Introduction Advanced Metering Infrastructure (AMI) consists of smart meters, data storage and management and communication systems.  AMI collects information from the end users and measures the energy consumption of the consumers as well as the generating power of the distributed generation system. SM provides information and/or alarms about consumption, events, power quality, tampering, etc. Conventional Electrical Meter Collect Data manually Customer Manual Billing Smart Meter Communication Interface/protocol Customer Gateway Communication Interface/protocol Datebase and Management system Metering architectures comparison of a conventional electrical meter and a smart meter
  4. 4. 4 Smart Metering System in AAU Intelligent MG Labs Ethernet Communication DC Power Line AC Power Line The laboratory is based on 6 workstations • 4 DC-AC converters, • LCL-filters, • ABB Motorized change-over switches • Two Kamstrup Smart-meters.  Configuration
  5. 5. 6  Communication Smart Meters  Collect data from the end consumers  Transmit data through LAN Data Concentrator  Receive the data  Transmit the data Utility Central (MDM)  Process the data received through Wide Area Network (WAN) 2-way 2-way Smart Metering System in AAU Intelligent MG Labs
  6. 6. 7  Smart meter collects the measurement data from the consumer and then transmit the data optically from the meter to a local computer which works as a data collector.  Point-to-point communication.  Communication - Optical Head Smart Metering System in AAU Intelligent MG Labs Reading events logReading meter data METERTOOL METERTOOL
  7. 7. 8  The data collected by smart meter can be transmitted from the meter to the utility central collection point by internet lines (TCP/IP).  Smart meter is able to communicate with an IP module connected via a LAN cable or with GPRS.  Communication – Internet based on TCP/IP • Two extra IP modules (IP101i), • A switch/ a router, • A Zigbee plug-in module, • An In-home display system.

  8. 8. 9  Radio Mesh, Power Line Carrier (PLC), Zigbee, 3G, GPRS, etc.  Other Communication Methods  Potential Benefits  From the consumer’s perspective • Estimate bills from the collected information and thus manage their energy consumptions to reduce their electric bills using in-home display .  From the utility’s perspective • Realize real-time pricing, by which the companies can limit the maximum electricity consumption and tries to encourage users to reduce their demands in the periods of peak load. • System operator can terminate or re-connect electricity supply to any customer with proper mechanism remotely in order to optimize the power flow or ensure power quality according to the information sent from the demand sides. Smart Metering System in AAU Intelligent MG Labs
  9. 9. 10 EUDP Sino-Danish Project  Granted by EUDP (Energiteknologisk Udvikling og Demonstration) and the Ministry of Science and Technology of the People’s Republic of China.  Be Carried out by Aalborg University and Tsinghua University (China), in cooperation with Kamstrup A/S and the Shanghai Solar Energy Science & Technology Co. Ltd.  A 200 kW hybrid PV-wind-battery microgrid site will be built and tested in Shanghai.  Research and small-scale demonstration will be in AAU Microgrid Lab Hybrid PV-wind turbine-battery Microgrid Rooftop Building PV system2*10kW Wind Turbine
  10. 10. 11  Kamstrup Omnia Description Future Works OMNIA Suite  An all-comprising smart grid platform  Formed based on AMI concept  Including smart meters, network communication, meter data management and smart grid features
