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


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.


Cost/Benefit Analysis for California Market

-$3,000 -$2,000 -$1,000 $0 $1,000 $2,000 $3,000 $4,000 $5,000 $6,000 $7,000

Net Present Value of Cost/Benefit (x$1000)

NPV of Costs/Benefits = $14.7B


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


Model for defining requirements

Consumer

Portal

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

METER

Consumer equipment information (response, load characteristics, etc.)

Consumer information and control

Alarms for utility applications


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.

Consumer Portal functions implemented by EDF : the residential meter

8 million electronic meters installed with :

�� Advanced utility services :

- Integrated ripple control receiver (for Demand Response)

- TOU (Time Of Use) Tariffs

- Remote reading with Euridis fieldbus (IEC 62036-31)

�� Customer interface :

- Contact outputs for load management

- Home automation fieldbus

Winter Super Peak

Winter/Summer Regular

Day

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)

Day ahead alert


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).

1 Automatic Meter Reading, 2 Automatic Meter Management


AMR versus AMM …

�--Prepayment

�--Reduction of Non Technical Losses

�--New tariffs (TOU, dynamic price, …)

�--Services beyond the meter (energy efficiency, multi energy aggregation)

�--Advanced load control (Power limitation, targeted curtailment)

�--Remote connection/disconnection

�--Switching Supplier and remote control of tariffs
