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.

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.

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.

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.

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
