Although not directly applicable to
such things as Substation engineering, there are standards bodies that
have placed their standards out in the public domain. One such body
is the ITU. The ITU and ISO do a number of things together, but a
majority of the standards are separate. There is some free information
from the IEC, but not much. You basically have to go hunting for
whatever you want to look at.
The ITU is slanted more towards telecommunications,
but then so is the Smart Grid. I've gotten a lot of ideas out of
ITU standards, especially in the area of security. Note that some
standards that are joint ITU and ISO are not available without a fee, but
most are free. The web site follows:

I would think so too, but wouldn't it be a major re-engineering
effort. Do you have any rough timelines for these standards to evolve and
mature?

It is regrettable but true, that the IEC standards are

standards to be developed elsewhere...

Hi Toby,
Thanks for the excellent summary on the smart grid requirements. You have
made references to ISO 61850
in the thread below, is this a specification
which is available for public download? It seems to be re-directing me
to a site,
which doesn't seem to contain any public downloads. Can you point me in
the right direction.
Thanks very much,

What Standards do we need for the Smart Grid
As I do periodically, I have been thinking about what standards
we need for the smart grid. The smart grid is more than improved top-down
control, it is a grid ready for unreliable energy sources (such as wind,
waves, and sun), distributed generation, and net zero energy buildings.
Net zero energy buildings are particularly troublesome because from minute
to minute, they may be buy power or selling power. The smart grid will
be transactional, with each purchase of energy at a market clearing price.
The smart grid will be open and transparent, wherein consumers can choose
what kind of power to buy, and providers can prove that they are selling
the kind of power they promise.
Earlier this week, Alex Levinson named the smart grid standards
Smart Grid Information Exchange (SGIX). So what are the standards we need
for SGIX?
-
SG Pricing: Price is more than a number. If
I ask you if prices are up or down at the store, the answer is not “7”.
It is not “Tomatoes are $3.00.” The price is “$3:57 per pound for the
organic vine-ripened greenhouse heritage Cherokee tomatoes.” Each buyer
can choose which attributes affect their purchase decision. I may choose
to buy the cheapest tomatoes. I may choose to buy only organic. I may grudgingly
choose the most expensive because they are the only ones in the store.
And I will be able to choose to run the fountain in front of my office
only when wind power is available and below a certain price.
-
SG Transaction: I buy what I buy at the time
that I buy it. That transaction may be different because of my price decisions
than what my neighbor is buying at the same time. I may owe for that purchase
of solar power to my utility or to my neighbor.
-
SG Market Operations: There is some bidding
and exchange of information in advance. In my mind, this looks somewhat
like commodity markets for those who want to participate. It includes elements
of weather arbitrage. It includes time and reliability. It includes all
of the elements of price. I am looking forward to GridEcon in March to
begin the discussions on SG Market Operations.
-
UnitsML: UnitsML offers an unambiguous way to
describe all physical measurements, and an unambiguous ability for a computer
to look up the translation of any units of measure to any other units.
I think UnitsML will be part of pricing and market operations.
-
WS Calendar: We all use ICALENDAR to unambiguously
exchange information about time intervals. You used it the last time you
clicked on an email attachment and suddenly had a meeting on your personal
calendar. We need the same functionality standardized for web services.
We will use it as part of pricing, and weather predictions, and other decisions.
-
WeatherML v2: I don’t actually know what version
WeatherML is on – but it is not usable. Most forward looking energy markets
are based on assumptions about weather. Most historical analysis of energy
use includes recalling the weather environment. The most successful energy
middleman base their business on understanding microclimates. We need a
standard way to report weather information, in whatever detail is available,
from forecasters, local weather stations, personal weather systems. Such
a standard should include UnitsML (for internationalization) as well as
time (WS-Calendar) and probabilities (for forecasts).
-
SG Interoperation: I envision this as a short,
light, exchange of the information we need to plug technologies together
without knowing the details. I see it as smaller than, but perhaps derived
from, ISO-61850. It includes some basic safety information. It includes
estimates of reliability and capacity. It may include some of the “price
attributes” (Am I a source of carbon-credit eligible power?).
-
SG Metering: This is a simple standard of energy
flows by time slice. It also includes direction, as power may flow one
way for a time, and then the other in a distributed world.
-
oBIX: The web service standard for technology-agnostic
operation or distributed control systems could well have a place Remote
Operation and Telemetry.
-
SG Telemetry: What is going on on the grid,
and where is it failing.
-
WS DD and WS DP: Device discovery and device
profiles have been used in computer networking for some time. Device Discovery
lets you find all printers on the network,. Device profiles let you decide
which printer to use when you want color duplexing. These functions are
being standardized for the web. Schneider, one of the largest conglomerates
providing systems for the grid and building is looking at providing WS
DD and WS DP for all the equipment it sells. I think it will have a big
role in the future world of distributed generation and net zero energy.
-
SG Remote Operation: This one may be a literal
transform from the ISO 61850 standard for substation communications.
Have I missed any?
