Improving the Architecture

• Transition from a research project to a system
  capable of supporting mission critical
  applications
• Robust, Reliable - Fault Tolerant
• Scaleable
• Secure and Manageable
• Eliminate dependence on specific underlying
  implementation technologies to lessen impact of
  technology change
• Meet the requirements identified in the DOE
  Report to Congress Section 1839, EPA2005 Steps
  to Establishing a Real-time Monitoring System For
  Transmission Grid Owners and Operators, Feb 2006.

System Requirements

• Reliable and Fault Tolerant
• No single point of failure
• Apply lessons learned from other industries
• Scalable
• Communications links can be added without
  impacting overall design
• Applications can discover new data sources
• Timeliness of Data Delivery
• Application requirements must be well known
• lt 200 ms for some apps, 10 s for others,
  historical
• System Administration and Security

Standardized Interfaces at Well Defined Points of
Interoperability

• Un-aggregated real-time phasor data stream input
• Aggregated real-time phasor data stream input
• Aggregated real-time phasor data stream output
• Historical database query / response, publish /
  subscribe interface
• Web based application interfaces

Message Architecture

• Message Brokers
• Publish / Subscribe
• Topic Trees
• Separation of data streams from the metadata that
  describes them
• Support browsing, data source selection

Summary

• The EIPP DMTT has
• Evaluated relevant architectures and has proposed
  a architecture that will support data transfer,
  synchronization, references and archiving
• Evaluated the known requirements for data
  management and handling.
• Identified several key system elements and
  interfaces
• aggregated real-time phasor data stream input
• un-aggregated real-time phasor data stream input
• aggregated real-time phasor data stream output
• historical database query / response, publish /
  subscribe interface
• web based application interfaces
• Recommended a reference architecture and also
  introduced the concept of Topic Trees to manage
  data and metadata.
• The system design utilizes well defined
  interfaces based upon industry standards and
  utilizes commercially available technology.
• The group still has significant work to complete
  within the EIPP but is well on its way to
  establishing a solid model for the other EIPP
  working groups
