AMI (Advanced Metering Infrastructure) is the core technology system supporting the smart grid. It realizes real-time collection, analysis and control of power data through two-way communication networks, smart meters and data management platforms. Its core goal is to provide energy suppliers and users with full-link digital services.
1. AMI Smart Metering Solutions Classification and cases of core application scenarios
(1) Intelligent control on the power grid side
Dynamic load regulation
Technical implementation: 5G communication + AI prediction algorithm (LSTM model) to predict regional power consumption fluctuation 24 hours in advance.
Case: Germany TenneT grid reduced peak load by 18% through the AMI system and reduced peak load cost by 230 million euros.
Distributed energy is connected to the grid
Technology realization: bidirectional metering chip (precision 0.2S level), support photovoltaic / energy storage real-time reverse power supply metering.
Case: In SunPower community of California, 80% of household photovoltaic self-use, and the cost of power purchase decreased by 42%.
(2) User-side deep service
l Optimize energy efficiency for industry and commerce
Scene: The steel plant dynamically adjusts the production plan of the valley power period combined with AMI data and the production rhythm of the electric arc furnace.
Benefits: POSCO Group saved more than $1.2 million in annual electricity bill per single plant.
l Personalized energy use by residents
Scene: Home energy butler (AMI + smart home linkage), air conditioning / EV charging automatically matching real-time electricity price.
Data: The average energy saving rate of Tokyo Electric Power users reached 15%, and the peak electricity consumption transfer volume increased by 37%.
2. Smart meter and AMI smart metering connections
As the sensing terminal of AMI, smart meters are responsible for data collection, while the AMI system is a more advanced data processing and control center.
