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. I am sharing it with these lists, with the note that while
it is OASIS-centric, it does clarify the path to information exchanges
necessary to get the smart load the smart grid needs. (translation note: EMIX = Energy Market Information Exchange
TC, now in formation) 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 a lot of 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 probably 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 Committee notes and Directions 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 "You can cut all the
flowers but you cannot keep spring from coming."
