    Hello All,

Please review and markup the linked document.

I took an action to make a strawman list of the actors that will make
appearances in our use cases.  I include at the bottom a cross-reference to
the OpenADR 1.0 actors/roles.

I have posted this document as a starting point for us to decide which
actors are imporant to us.  I aired on the side of including as many as I
could think of.

There is no pride of ownership here because this is a very rough strawman
to move us forward.  Please edit mercilessly.

Again, thank you for reviewing and commenting on/marking-up the attached
prior to next week's meeting. 

Regards,
Dave

p.s. Note that you can use the OASIS document comment feature to make
overall comments.

p.p.s. Many thanks to the OpenADR contributors for their patience with us
as we disassemble & reassemble something that they worked on so
dilegently.

    Hi David,

This is excellent and quite comprehensive. I know this document is the starting point but I just want to make sure I understand the reasoning behind your categorization. For instance, why would we have Load Generating Organization, Generation Operator, and Local Generation System? 

Secondly, in your view, do you think we should also come up with organizational use cases as well?

With kind regards,

    Hi Michel,

In response to your questions:

>> why would we have Load Generating Organization, Generation Operator,
and Local Generation System?

I don't know that we should.  My favorite book on use cases is Writing
Effective Use Cases by Alistair Cockburn.  He advocates a hierarchy of
use cases from Summary ("cloud/kite"), User Goal (sea-level), and
Sub-function (underwater).  

Different DR groups start at different levels.  I listed each level to
provoke the conversation about what level of actor we should document.

>> Secondly, in your view, do you think we should also come up with
organizational use cases as well?

I lean toward starting at the highest level that makes sense. For
businesses, I find it easier to say that the organization has a goal
rather than to make assumptions about how any particular company
executes these goals / delegates the goal.  

What do you think?

Best Regards,
Dave

    Hi David,

I am so very sorry for a tardy reply.

I totally agree with you. Let's get started!

    Good effort.

Where we can, we should try to align our big classifications with the domains of the smart grid as defined in the roadmap.

http://www.nist.gov/smartgrid/

last public version:
http://www.nist.gov/smartgrid/Report%20to%20NISTlAugust10%20(2).pdf
The Conceptual Model begins on page 20.

It names the following domains:

Operations
Markets
Service Provider
Bulk Generation
Transmission
Distribution
Customer

Of course, the principle of symmetry in smart grid definitions acknowledges that the microgrid customer may simultaneously be the distribution operator, with generation and customers contained.

The proper end point for Energy Interoperation is the Energy Services Interface (ESI). The ESI may be a face on an enterprise oriented Energy Management System, or, when there is a single or predominant Building Automation System (BAS), it may be a face on the BAS, or it may be a utility supplied direct control system (turn off the single window unit in the trailer). In each of these cases, and in many more, the single undifferentiated end point for Energy Interoperation is the ESI.

If we had a market and technologies for a pure economic interface, that would be the end of it. Forward predictions of energy pricing and well developed pricing strategies would be sufficient to induce effective storage management. Today's markets and business models will not let us leap this chasm in a single step (though as the image acknowledges, it is much more difficult to leap a chasm in two steps than in one).

So what are the things that break this clean model?

1) Storage Management, for now. (But that model is coming from another group, to be received by this group in November).

2) Peak or Spike management (or is this just a specific problem within Load Shaping?)

3) Sale-back

Personally, I am growing more and more convinced that except for industrial sites, sales-back may never be fully economic. I think car batteries will be used, if at all, for load management within the facility that house them. I think that a side effect of the markets enabled by EI will create better site storage, and that feeding the site storage will be the best use for most excess site generation.

In any case, we have the big terms and the primary definitions from the roadmap. If the roadmap is wrong in some detail, we should identify this explicitly. If we are merely fleshing it out, we should consider feedback to the smart grid standards board.

Question to the group: Should we include an explicit short (one page) call out to the national smart grid conceptual model in the EI document?

    Agreed. When do we start?
