It is good that the 'blurring between DR and DER is
being recognized...my goal is to 'blur' not just in the middle but the rest too.
The key word in DER is "Distributed", and ultimately I see distributed control
as the key feature. The 'response' to 'demand' MUST be a lot more options than
just turning things off: Ultimately I think in terms of distributed energy
management, where the local energy management entity responds to the signals
depending on the resources it has available. But that's just me (a
distributed kind of guy :-).

Subject: [smartgrid-interest] 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.
