configuration of the network as a whole. It also tracks operational status of AMI
communications.
4.3.7 Demand Response Analysis and Control System (DRAACS)
A DRAACS sends demand response event notifications to meters and load control
devices through the AMI system. It provides demand response options to operators,
market traders, etc. based on predefined groupings of customers and statistical analysis of
how those customers have responded in the past.
4.3.8 Field Tool/Device
Field tools and devices are portable computing systems used by field personnel to
connect to components in the field to perform maintenance, upgrades, diagnostics, and
similar activities. It has a wireless connection to utility systems, which communicates
information utility field personnel may need to perform installations or other service.
4.3.9 Grid Control Center
A Grid Control Center component comprises the utility’s operations centers; real-time
data and software applications used by those centers (e.g., EMS and SCADA); displays
used to facilitate decision making; and applications outside of the operations center that
interact with applications used for grid control.
4.3.10 Meter Data Management System (MDMS) 8
An MDMS aggregates, validates, estimates and permits editing of meter data such as
energy usage, generation, and meter logs. An MDMS stores this data for a limited
amount of time before it goes to a data warehouse and makes this data available to
authorized systems.
4.3.11 Non-Electric Meter
Non-electric Meters are components used for metering non-electric services (e.g., gas and
water meters). Non-electric Meters sometimes use AMI networking infrastructure to
provide information back to non-electric utilities. Like AMI Meters, Non-electric Meters
are deployed in the field, and as such have limited physical protection.
4.3.12 Third Party Meter/Submeter
A Third Party Meter/Submeter is a metrology device that allows for the monitoring of
usage on a portion of a distribution network past (at a finer granularity) a main meter. A
submeter may not be owned by the utility. Third Party Meters/Submeters are deployed in
the field, and as such have limited physical protection.
8 This component was labeled MDMS: Meter Data Unification System in the source scenarios.
