Smart Grid Definitions
• Different Things to Different Utilities
• Fuzzy Definition – Coverage from Generation to
Consumer
• DA, AMI, Communications, Asset Management
• Generally Implementation of Pertinent Subsets
Smart Grid Characteristics

• Accommodates all generation and storage options
• Enables new products, services and markets
• Provides power quality for the digital economy
• Optimizes asset utilization and operates efficiently
• Anticipates & responds to system disturbances (selfheals)
• Operates resiliently against attack and natural disaster

– remotely program changes for autonomous controllers
– real-time remote monitoring control operations
Smart Grid Systems
• Distribution asset management system

CIM Compliant
Data Model Mgmt
For all applications
Existing
• Gateways exist that support RTU, IED, and Relay data access to be made
available to enterprise
• IEC 61850 currently offered for protection and control devices within
Substation
• IEC 61850 currently supports IP based communication systems and uses
deterministic protocols to minimize latency in command/control
communication
Future
• CIGRE Working group currently investigating expansion of IEC 61850 for
outside substation applications
Existing
• Common Information Model (CIM - IEC 61970) data management tools exist
which allow CIM compliant off-the-shelf CIM/XML import & export adapters to
synchronize network model data with other network data repositories like
ESRI, SmallWorld and Intergraph GIS solutions.
Future
• Committee continually expands CIM data model to cover a broader range of
applications which will support exchange of data between Asset
Management, Network Modeling, and Distribution Management System
components. This evolution will lead to condition-based assessment data that
can be interfaced with reliability-based network planning tools for online
decision support and operational contingency planning.
What Exists Today And Future Functionality To
Deliver Smart Grid Data?
Wireless Broadband Network
Existing
• Broadband wired, wireless and BPL networks already exist
• Wireless mesh networks can support incorporation of grid asset
communication, but currently require additional infrastructure to reduce
recursive communication between meters and meters to towers. These could
be converted to broadband IP-based networks as cost comes down.
• Domain provisioning available to support low latency communication
