Subject: Report coming out of Smart Grid SDO Conference
|
I prepared the attached schedule as a summary of issues most
relevant to the Energy Interoperability TC coming out of the Smart Grid SDO
Conference on August 3-4. We will want to discuss it on the next call. High Level overview: WS-Calendar will be done by year end, to be used as a
component in Price and in Energy Interoperability. We can use place-holders until
then. EMIX, now in formation, is due out for review in April 2010.
EMIX will itself consume WS-Calendar. EMIX (Price/Product) is critical to almost
every Energy Interoperation – we will have to use placeholders until then. NIST will unveil the Smart Grid Roadmap, based upon the EPRI
work, at GridWeek in September. Numerous groups are working on the common semantics, use
cases for Price, Product, DR, and DER. These groups are due to complete their
work in October, for report-out at GridInterop in November. These reports will
be donated to Energy Interoperation and to EMIX. Issues from the Workshop Prices and Pricing. These words created the most discord.
Dynamic pricing is an appropriate goal for Energy Interoperation. Pricing is
not. Pricing, to many, refers to algorithms as to how a price is computed. This
conflict of terms caused much dissension, discussion until we recognized the
issue. EMIX communicates Prices, not Pricing. Product Attributes. Mike Oldak brought one half of the room
around when he declared that Product Attributes are better referred to as Terms
and Conditions. This is probable a good lens to look at this issue with Also from Mike Oldak There are three kinds of DR: -
Pure prices, and you can do what you want -
Contracted Response, in which the end node responds as
per contract when signaled -
Emergency Curtailment Energy Interoperation includes DR and DER. DR and DER blur
in the middle: turning something off or running on stored energy have the same effect
on the grid load. The Committee Draft 1 for Energy Interoperation would benefit
from the clarity of this summary. In terms of grid interactions with the end nodes, there is
another fast track initiative on sharing customer energy usage with the end
node and delegable to third parties. This standard, current with the overly
general name ADE (Automated Data Exchange) can present one of the longest
requested sources of information to the building and home automation market. The Energy Interoperation Committee may want to create a
subcommittee to prepare white papers on Energy Interoperation and the many
standards. Such a white paper could revise and extend the narrative portions of
the CEC OpenADR specification, and create models defining communications
between end nodes and the grid. EMIX to understand what’s on the market,
Energy Interoperability to negotiate price and response with the grid, and [son
of ADE] to act as the feedback/regulator. tc "When one door closes, another opens; but we often look
so long and so regretfully upon the closed door that we do not see the one
which has opened for us." -- Alexander Graham Bell
