Industry-Level Architecture Development: Integrating the Developing InfrastructuresJoseph Hughes

Electric Power Research Institute Palo Alto, CA


Developing System Architecture

• Definition of an “Architecture”– Defines the overall structure, organization,

performance and management of a distributed computing system

– Enables: • Analysis of system-wide technical and business issues such

as interoperability, scaleability, management, security and related technical infrastructure

• Communications among stakeholders


What is an Industry Level Architecture?

Architecture: The Structure of Components, their relationships, and the principles and guidelines governing their design and

evolution over time*.

*DoD Integrated Architecture Panel, based on IEEE Std 610.12


Drivers behind Architecture Development

• Systems development lack an overall enterprise-wide implementation perspective

• Infrastructure is underspecified – Unable to scale up from demonstration “pilots”– Major issues not addressed systematically

• Integration across the enterprise• Integration across the industry• Data sharing, hardware resource sharing• No Integrated System Management • “Stovepiped” systems• Disparate Standards Initiatives


Need For Architecture Level Development

• Applications cut across traditional technical domains:– Real Time Systems and Information Technology– Generation, Transmission, Distribution, Consumer

Systems Integration– Standards need to be more rigorously integrated as

they develop– Cross Industry Integrations are necessary:

• Communications and Advanced Automation• T&D operations and Building Automation• In Building Integration, HVAC, Appliance, Consumer

Electronics


Architecture Challenges

• Technical Discipline of Architecting Large Scale systems still seeking to mature

• Standards for Architecture Development in development• Standardized Notation(s) known as “Architecture

Definition Language” are still under development• Developing Standards at a component level is

inadequate for future higher levels of integration

Several Disciplines Need to Come Together

?


Work is needed in key areas:

• System Operation and Protection Applications: Necessary to operate closer to limits, need to integrate data and applications across Gen,T&D, Consumer Comm

• Need to integrate Dynamic Consumer Energy and Demand Response

• Need for a robust application level common language that can cut across the major technical domains

• Need advanced Systems Engineering Methods that are capable of massively scaled and robust systems

• Need a Roadmap• Need to work Cooperatively
