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
