Definition
AMS (Advanced Metering and Control System) is the designation for the smart electricity meters that Norwegian grid companies were required to install at all grid customers by 1 January 2019, in accordance with requirements from NVENorway's Directorate of Water Resources and Energy - regulates the electricity and water resources sectors.. An AMS meter records electricity consumption automatically hour by hour and transmits the data to the grid companyCompany that owns and operates electricity grids and is responsible for power supply to end users. without the need for manual reading. Unlike the old Ferraris meters, the AMS meter can communicate bidirectionally - the grid company can send commands to the meter, read real-time data, and in some cases disconnect the power supply remotely. The meters typically communicate via PLC (the power network as a communication cable), mobile network (GPRSPacket-switched mobile data standard (2.5G) used for remote reading of electricity meters./NB-IoTLPWAN communication standard optimised for low power consumption and good indoor coverage - replacing GPRS in new AMS infrastructure.), or other radio technologies. The data is sent to the grid company and forwarded to ElhubNational hub for metering data and market processes in the Norwegian electricity market. for market use. AMS meters also have a HAN portHome Area Network - communication port on smart meters enabling end users to extract their own electricity data in real time. that gives end users and third parties access to real-time data. The rollout of AMS was a prerequisite for the digitalisation of the Norwegian power market and laid the foundation for the AMIAdvanced Metering Infrastructure - comprehensive system for two-way communication between smart meters and power suppliers' systems. systems that grid companies use today.
