EI Schemas from 4/5

Looks like a semantics problem to me. It seems to me that deployment could be in units other than MW. I have been assuming that is always Real Energy, but would the deployment also be expressed as Active Power? I am also curious to know if DR Event objectives would also apply to voltage control.

Subject:
[energyinterop] EI Schemas from 4/5

I just started cleaning up the EI schemas submitted on April 5, in preparation to work on putting together market context. I began by pointing to permanent references:  iCalendar the web-located PR02, emix to the PR02 version, not yet on the web, etc.

I then started running through the eiEvent objects and found something that I have to un-ravel. We seem to be pre-judging objects in ways that can lead to internally inconsistent outcomes.

For example, we have a DeploymentMW type that references real energy, something that has  Watts  and Scale inside it. We should not be able to specify MW in a scale of K (or T, for that matter). Accordingly, I am going to make a quick run-through and remove that semantic override of the underlying data.

In a similar way, many of these have hard coded RealPower (or RealEnergy) types. Do we want to disallow the use of EnergyInterop to dispatch, say Reactive Energy? For this reason, I think I need to back off to more generic energy and power types.  If OpenADR wishes to restrict its use to only the Real types, it is of course free to do so.

Overall, the event object looks considerably more useful than before, and with a cleaner structure.
