Experiences from Vietnam Smart Meter Reading Pilot Project Presenter: Dr. Ngoc Thien Le Department of Electrical Engineering, Faculty of Engineering, Chulalongkorn University
Authors Professor, Dr. Watit Benjapolakul and Dr. Ngoc Thien Le, Dept. of Electrical Engineering, Chulalongkorn University Mr. Sang Dinh Ngoc and Mr. Dinh Truong Cong, Dept. of Urban Engineering, Univ. of Architecture, Ho Chi Minh City, Vietnam Mr. Thai Hung, EVNCPC Electric Utility, Vietnam My colleges in Vietnam are: Mr. Sang Dinh Ngoc, Mr. Dinh Cong Truong and Mr. Thai Hung
Why smart meter? Utility Customer Operation and Maintenance cost; Workforce cost; Forward to smart applications: Demand Response; Peak Load Reduction; Real-time Energy Theft Detection Customer E-Bill and Online Payment; Social impact; Changing behaviors: Real time price
Challenges Interoperable: many smart meter’s manufactures Communication network Wireline vs. Wireless Dedicated vs. Shared Licensed vs Unlicensed Bandwidth, real-time Toward: Smart Grid, Internet of Thing
Vietnam Smart Meter Pilot Project Named as: RF-Spider system 14 provinces of Central Vietnam Start from 2011
Smart Meter Network Wireless approach: mesh network Smart Meter <-> Data Collection Unit (DCU): using unlicensed bands: 408.925 MHz and 433.05 MHz 406.1 MHz-430 MHz: Terrestrial Fixed Service 430 MHz-440 MHz: Radio Location DCU <-> Utility’s Data Server: 3G mobile network Router: relay device between Smart Meter and DCU
Smart Meter Network Based on the road, and distribution transformer locations
Devices Router DCU Assembled in Vietnam, by EVNCPC 1-phase meter
Experiences: placement DCU
Experiences: placement Smart Meter
Experiences: network
Experiences: performances Add more Router if the RF links are unstable; The total connected smart meter per DCU: about 99.2%; DCUs are died by lightning; Smart meter’s distribution: 2 dimensional Poisson distribution
Experiences: Server Storage
Future Upgrade: 4G mobile network; RF-SPIDERGIS: integrate with geographic information system (GIS); Day-ahead price for main customers; Long term: Advanced metering infrastructure (AMI)
