Meter data management
|This article needs additional citations for verification. (June 2012)|
Meter data management (MDM) refers to a key component in the Smart Grid infrastructure that is in the process of being evolved and adopted by utility companies. An MDM system performs long term data storage and management for the vast quantities of data delivered by smart metering systems. This data consists primarily of usage data and events that are imported from the head end servers that manage the data collection in Advanced metering infrastructure (AMI) or Automatic meter reading (AMR) systems.
An MDM system will typically import the data, then validate, cleanse and process it before making it available for billing and analysis.
Solutions based on meter data include Smart meter deployment planning and management; Meter and network asset monitoring and management; Automated smart meter provisioning (i.e. addition, deletion and updating of meter information at utility and AMR side) & billing cutover; Meter-to-Cash system, workforce management system, asset management and other systems. Furthermore, an MDMS may provide reporting capabilities for load and demand forecasting, management reports, and customer service metrics.
An MDMS provide application programming interfaces (APIs) between the MDMS and the multiple destinations that rely on meter data. This is the first step to ensure that consistent processes and 'understanding' get applied to the data. Besides this common functionality, an advanced MDM may provide facility for remote connect/disconnect of meters, power status verification\power restoration verification and On demand read of remote meters .
