Peak Power Shaving and Last Gasp Power in Smart Cities
Smart Cities are made up of a network of interconnected intelligent sensors, all relaying information to each other and to the city itself. One use case at the heart of smart cities is the ability to intelligently manage power. Automatic Meter Readers (AMR) have been installed in many cities and were a first step to an intelligent city. Today Advanced Metering Infrastructure (AMI) is being deployed across cities allowing for a never before seen ability for individual devices to interact with the city and the city to interact with devices. These AMI devices are always connected and provide two way communication and they must do this all with very little power usage.
Ultracapacitors, traditionally used in last gasp backup power for AMR systems, are seeing a new role in AMI. When combined with a small battery, supercapacitors are able to provide the peak power required by the wireless modems during transmission and the battery provides long term power to the system, allowing AMI power meters to listen and transmit data even during a power outage.

7 年"allowing AMI power meters to listen and transmit data even during a power outage..." and probably be able to hold on to those momentary outages a bit longer (because of the additional capacitive backup from these Ultracapacitors), so that the Sustained Outages being reported to the OMS are more refined, Peter P.?
