There are a number of standards groups that do not charge to view their standards: IETF, W3C, ECMA, OMA, IEEE, ETSI and OASIS (Toby's favorite) come to mind. And, sometimes the process goes through a non-paid organization (say IEEE Computer Socicety) which is not paid, gets recognized by an organization that does charge...so you get to pick which version you want to use, when much of the time they are the same thing just with different approvals, numbers, and cover pages.

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 "pay per view". Some think this a a good reason for smart grid 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,

I have had the pleasure of some stimulating conversations in the last few days about a standards roadmap for the smart grid. As I often do when pondering, I blog to crystallize my

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?
