IntelliGrid - Vision of the Power System of the Future
OBJECTIVES:
Self-Healing and Adaptive
Interactive with consumers and markets
Optimized to make best use of resources and equipment
Predictive rather than just reacting to emergencies
Distributed across geographical and organizational boundaries
Integrated, merging monitoring, control, protection, maintenance, EMS, DMS, marketing, and IT
More Secure from attack

The Consumer Portal
“A combination of hardware and software that enables two-way communication between energy service organizations and equipmentwithin the consumers’ premises.”

What is a Consumer Portal?
`
ADSL
PLC
CableNetwork
SONET WAN
EMS
`
Portal in a meter
Portal in a local energy management systemPortal in a stand-alone device or PC
Portal in a set-top box

Consumer Portal Applications
Metering aggregation for multiple sites or facilities
Outage detection and notification
Metering information and energy analysis via website
DG (backup) Aggregation for Market Participation
Building energy management systems
Direct Load Control (e.g. radio), controllable thermostats
Special load control during peak periods
Time of Use Rates
AMR (radio and low speed PLC)
Current Applications (examples)
Customer monitoring integration with FSM
Theft control
Remote equipment performance diagnostics
Facility sub-metering and energy analysis
Remote power quality monitoring and services
Automatic load controls integrated with RTP
Integration of customer-owned generation
RTP for customer market participation
Continuous metering information available to customer
Future Applications

Example – Demand Response
7© 2005 Electric Power Research Institute & EDF R&D, Inc. All rights reserved.
Example Response to Pricing Signal (California)
• Portal adjusts load when the new rate hits:
– Increases thermostat setting
– Turns off water heater
• User could have provided input:
– Viewed the tariff change
– Adjusted settings
– Viewed $$ savings
• But not necessary!
• Portal reacts anyway.

Distribution Operations – the untapped potential of a real time consumer interface
• Outage Management
– Outage detection and integration with outage management systems has the potential for dramatic improvements in reliability
– Fault location allows fast dispatch of crews
– Integration with automation systems allows automated restoration to affected areas
– Monitoring capability assures crew safety
• Power Quality Management
– Voltage/var management based on real-time monitoring data
– Identification of PQ problems before there are equipment impacts (e.g. harmonic distortion levels, unbalance, voltage fluctuations)
• Distributed Generation Integration
• Distribution Planning
– Accurate load modeling and load forecasting
– Improved system planning models based on actual data

How could portals make money?
Lessons Learned – from dozens of past attempts
• The technology exists
– No breakthroughs are necessary
• Make it simple
– Customer must be able to not participate
• Standardize
– Don’t try to “lock in” customers to proprietary systems
– Achieve economies of scale and reduce costs
• 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

Information needed by utility about consumer loads and equipment
Information needed by consumer
Control signals to consumer loads and equipment (e.g. direct load control)
Information to consumer equipment for intelligent applications (e.g. price signals)
Control signals for consumer loads and equipment

General requirements of the consumer portal
• Two-way communications between utilities and end-users with higher data rates and standard protocols.
• Support a wide variety of services that can take advantage of the communication and control capability.
• Standardized information models for these services so that products from multiple vendors can be inter-operable.

Different TOU rates are already implemented in France :
� Peak hours : 10 million customers
8 off peak hours (-40%) on night or day
Load control using water heater
Monthly subscription
� Critical Peak Pricing : 900.000 customers
22 peak days maximum during winter (max : 5 consecutive days)

The European context is evolving
� Utilities are willing to increase customer services to be competitive in a fully deregulated market.
� More and more actors are asking for frequent metering data.
� European Directives« Measures to safeguard security of electricity supply and
infrastructure investment »
« Energy end-use efficiency and energy services »
����These directives could push the development of AMR1 or AMM2.
� The French regulator asks for standard communicationprotocols and interfaces (www.cre.fr).
