General Commentary

� Smart Grid is an all encompassing term

> Smart Metering / Advanced Metering

> Smart Network

> Distribution Automation

> SCADA

> Synchro-phasors

> Consumers empowerment

� Value of smart grid to consumers

� Bakersfield impact

� Maryland impact

� Maine & CPUC exclusion impact

Smart Grid Network - Acronyms

� Neighborhood Area Network (NAN)

� Local Area Network ( LAN)

� Regional Area Network ( RAN)

� Metropolitan Area Network ( MAN)

� Field Area Network ( FAN)

� Wide Area Network ( WAN)

� Home Area Network ( HAN)

� Personal Area Network ( PAN)

� Generally LAN = NAN & RAN= MAN

� LAN +RAN = FAN

� PAN ≠ HAN if PAN+FAN≠WAN

Impact of Standards

� Standardization & Commoditization of Smart Grid is very

good for consumers & rate payers – but:

> It is painfully long & complicated

> Interdependencies

> It chooses winners and losers ( often inadvertently)

> It does lead to Market confusion during evolution process

� All layers of Smart Grid Networks are moving at different

speeds – making adherence very hard.

Understanding the Standards terminology

� Compliance

� Conformance

� Certification

� Interoperability

� Adoption

� Adoption of ALL standards is de facto assumed by the

customer

Example: IP ( Internet Protocol ) is just one of the MANY

Standards that Smart Grid Systems will need to conform to

and be certified to demonstrate interoperability for general

adoption

Understanding Smart Grid Security

� First – No Panic Button

> There are hundreds of very smart people

working on Smart Grid Security

� Smart Grid Security Concerns are Real

> Best way to understand them is via “Threat

Model”

� Security implementation cannot be an

“after thought”

> No point putting on the locks after the theft!

� Security Architecture may not be a problem

> Non Prudent implementation would be the

bigger culprit

Interoperability –Achieving a Seamless Smart Grid� IntelliGrid ( EPRI) Attributes of Compliance guidelines for

Smart Grid Devices

� The building blocks (hardware, firmware, software, middleware) of an Intelligrid compliant system have the following attributes:

> Support object modeling

> Employ self description

> Support the concepts of common services and generic interfaces

> Based on open, published standards

> Well defined interfaces and points of interoperability

> Facilitate device and network management

> Permit the implementation of adequate security policy

> Implements time synchronization
