Smart Grid Program

The architects nightmare of 2007

Unprecedented interoperation with other equipment companies, markets

Unprecedented technology expenditure on new technology, new methodology, new benefits

No-one was talking the same language and many people thought they could all talk what they called end to end.

Few had a vision of how big end to end would be

– Would a service provider dealing with the premises receive the same data that the utility received after various translations and transformations.

– Would the utility and service provider want to exchange the data they both received. Should it be similar?

Need for a thoughtful, tested, well architected, collaboratively created direction and validation of customer benefits



Smart Grid Program

The Architecture and development methodology

Assessment SAP, SCADA, OMS, 3 MDUS vendors, 7 network vendors, many

smart appliances, many smart devices,many Service providers Premises effecting tests, outages, disconnects, etc.

Field Pilot Quasi production environment for controls & processes Study and operate vendors/technologies as designed by

architecture Rigorous functional testing and operational performance Up to 4 network vendors Test business case assumptions

Q3 2010

FinalArchitectural

Recommendation

Mass Deployment

Highly Structured Environment:

* Full scale production environment

* 3.5 million meters

Architecture• Design of the network, systems, interfaces,

applications, etc.

• Work with vendors on system technical requirements and standards

Smart Grid Program

Goals of the Smart Grid Program

Consumers Energy expects efficiency in:– Energy Delivery– Outage restoration– Customer service– Customer energy usage– Response to price

Business Case life cycle design– Design for layered architecture– Design for upgradable architecture– Design for commonality in phy/mac/network where possible– Design for optimal Common Information Model– Build on IEC internationally accepted standards and work to make

them what we need



Smart Grid Program

Strategy for getting key suppliers to use standards

Translation and Transformation is at best a necessary evil Standards need extensions to meet requirements Users need to get together in task forces to state requirements Incorporate industry best practices extensions into Standards. Consumers Philosophy

– Work with others and collaborate don’t build a one off– Through users groups speak with a common industry voice– Get many areas moving to the same standard– Validate reality over geek speak– Put your money and your time where your mouth is.– Save money through economy of scale and simplicity of solution



Smart Grid Program

Examples of effort

UCAIug Board Of Directors, OpenSG committee member SG-Systems Co-Chair funding AMIent Chair and Co-Chair funding AMInet Chair team member NEMA task force member, NAESB SG task force co-chair Zigbee alliance, Homeplug Alliance, IEEE P1901, 2030, etc. Funding WG14 international convener SAP lighthouse council

– Working with development team on changes for CIM compliance– Working with MDUS vendors towards CIM compliance– Working with OMS, and AMI vendors to become CIM compliant

Testing End to End / Cross domain / In real working environment Test to scale

Supporting the Smart Energy Profile 2.0 Development



Smart Grid Program

Following a similar process for the HAN

Define functional requirements for SEP 2.0 Technical Requirements Document (TRD);

Develop SEP schema and service design based upon AMI-ENT architecture patterns and design principles

Extend the CIM as required to meet SEP data requirements

Develop SEP Sequence Diagrams

Submit use cases, recommended CIM extensions, and recommended XSDs to IEC TC57

Conclusions and Lessons learned

Start with the end in mind One offs are much much easier (and you don’t have to ask anyone) To many people deploying one offs while hoping to retire early Pros/cons in working with user groups to drive industry standards Artificial tests and brochures are no substitute for the real thing No one is big enough to drive this market CIM is not complete but is the best thing available Only through acceptance and openness to industry best practices can

CIM advance at the rate that is needed
