The Power Delivery System of the Future Must Have Advanced Capabilities

• Self-Healing and Adaptive to correct problems before they become emergencies

• Interactive with consumers and markets

• Optimized to make best use of resources and equipment

• Predictive rather than reactive, to prevent emergencies ahead rather than solve after

• Distributed assets and information across geographical and organizational boundaries

• Integrated to merge all critical information

• More Secure from threats from all hazards

To achieve benefits identified by stakeholders, the intelligent grid must be:

What is Impeding the Industry?

• Lack of interoperability• Limited methods or

tools for designing complex systems

• Incomplete, overlapping and conflicting standards

• Lack of a common “vision”

• Regulatory and financial uncertainty

• Perceived investment needed

5

The IntelliGrid Architecture

• An open, standards-based architecture for integrating the data communications networks and intelligent equipment needed to support the Power Delivery System of the Future

• Provides utilities and others with the tools and processes for designing communications and automation systems

• Recommends technologies and standards to use

Examples of Intelligrid Architecture Recommendations

Apply ASHRAE

BACnet™ for Building

Automation

Apply ANSI C12 for Revenue Metering

Apply IEC 61850 for Real-Time Controls

Apply IEC 61970 and 61968 for

Enterprise Data Sharing

R&D: Harmonize IEC 61850 and 61970 Standards

Develop and implement consistent systems management and security policies

Intelligrid Architecture Business Drivers

• Capital Cost Savings

– Competitive Procurement of intelligent equipment through Standards and Open Systems

– Multi-vendor support and avoidance of single vendor “lock-in”

– Extensible and Scalable “Industry-wide”

• Life-Cycle Cost Savings

– More uniform Standards based systems

– Extensible for the Future

– More capable, easier to maintain

– Immune to single vendor limitations

• Security Policy Implementation

What are the Applications?

Current Applications (examples)

AMR (radio and low speed PLC)

Time of Use Rates

Special load control during peak periods

Direct Load Control (e.g. radio), controllable thermostats

Building energy management systems

DG (backup) Aggregation for Market Participation

Metering information and energy analysis via website

Outage detection and notification

Metering aggregation for multiple sites or facilities

Future Applications

Continuous metering information available to customer

RTP for customer market participation

Integration of customer-owned generation

Automatic load controls integrated with RTP

Remote power quality monitoring and services

Facility sub-metering and energy analysis

Remote equipment performance diagnostics

Theft control

Customer monitoring integration with FSM

Lessons Learned – from dozens of past attempts

• The technology exists.– No breakthroughs are necessary

• Make it simple.– Functions should not require customer intervention

• Standardize.– Don’t try to “lock in” customers to proprietary

systems– Achieve economies of scale and reduce costs

• Share the infrastructure.– Use portal-like services from other industries

• Build an architecture.– Integrate the portal with the whole energy system– Don’t create “islands of automation”

• Don’t strand assets.– Make it easy and inexpensive to upgrade– The best applications may be yet to come

• Share the benefits.– Distribute the “societal benefits” to everyone

12

What Could a Portal Look Like?

• A consumer portal is an idea, not a particular device!

• IntelliGrid is developing a reference design

– A standard “virtual appearance” for a portal

– A clearly defined set of interfaces

– May be incorporated into a variety of devices

– May be distributed among several devices

• The physical device(s) may vary, but the virtual device must be standardized to ensure

– Interoperability between vendors

– Reduction in cost due to economies of scale

• Some vendors already provide portal-like devices, but they are generally not standard and not interoperable.

13

IntelliGrid Consumer Portal Project

• Define requirements so that vendors can build components and systems that are interoperable (open systems).

– Information models, object models

• Define requirements so that systems will be expandable to meet needs of future service offerings.

• Engage stakeholders to create a consensus on these requirements definitions.

• Demonstrate the feasibility and performance of systems that meet these requirements.

• Move these requirements into the standards process to enhance the applications in the market.
