Smart Grid
Smart Grid Definition
“A smart grid is an electrical grid that
communicates information to automatically act on supply
and demand thus improving the efficiency, reliability and
sustainability of the production and distribution of
electricity.”



Smart Grid + Smart Water + Smart Gas = Smart Energy
TÜV Rheinland is committed to the development of
Smart Energy Profile 2.0
Evolution of the Smart Grid

Balancing the Supply and Demand
Automatic Meter Infrastructure
Communication to the
meter to gain access on
billing information.
Development of smart
meters. Reporting of
outages. Determine
leakages (theft of power).
Bi-Directional Communication
Demand side
management such as
time of use (TOU)billing
profiles. Supply side
command and control
such as demand

Certified Compliance Testing

ZigBee Smart Energy is the
world's leading standard for
interoperable products that
monitor, control, inform and
automate the delivery and use
of energy and water. It helps
create greener homes by giving
consumers the information and
automation needed to easily
reduce their consumption.
Looking for a timely and cost effective way to simplify
your wireless product integration?
Now you can pre-test your ZigBee® product for compliance, functionality
and interoperability before certification.
TÜV Rheinland’s ZigBee Test Tool
includes software and a 2.4 GHz
radio to let you perform your
own product emulations with
granular condition cycling to
de-bug your devices as they are
being developed
.

SunSpec Alliance

Value Proposition: Creation of a common command
language for inverter manufacturers so as to provide
interchangeability and ubiquitous command and control of
solar power plants.
Common Denominator: 1547.1(a)
Advanced Inverter Testing

Any significant change to the command and control of inverter systems requires a testing
or retesting of the electromechanical grid interconnect.”

Flow For Smart Grid Projects

• Functionality
• Specifications

• Certification and Compliance
• Interoperability

• Cyber Security
• End Point Hardening, Penn Testing
Cyber Security is needed to prevent:
 Malicious data attacks (AMR billing changes)
 Targeted attacks (System interruptions)
 Kinetic Damage to Grid Assets (Warfare)
Interoperability As a Product

Extremely needed in the industry as the ecosystem expands and products are
offered in the retail channel.

“As the Smart Grid develops in
scale and technology, keeping the
stakeholder’s primary interests of
interoperability through engineering
and testing is indeed a herculean
effort.

As the Internet Of Things moves
towards IPv6 and 6LoWPAN, many
technical hurdles present
challenges.

It is being precisely right with the
details which will achieve the
desired goals.”
