Great start, Sila. To the list I’d
suggest adding the building or facility’s bid/ask price for consumption/DER
over the relevant time period(s).
This could, and probably should, be iterative
with the “Grid”, which might be multiple institutions, providing forward
costs for different intervals and buildings responding.

If the grid has the historical data from each facility plus weather
data from each location, it can generate forecasts for each building as well as
the aggragate. The building's prediction is an fyi for the grid This
happens in the grod between utilities and ISOs all the time sort of like
a check/balance but may not be necessary if not trusted.

The grid usually forecasts load in the aggregate.
What is the building forecast for? If it is a baseline for a DR program,
then who should be responsible for the forecast? The customer should not
do it, because of the incentive to bias the forecast.

questions for discussion
Traditionally, building load management has been crude,
and aggregated in certain large time granules. Industrial sites, however, have
had strong incentives to manage peaks.
As operating safety margins get smaller, it may become
increasingly important to manage peaks aggressively, even within the neighborhood
or even home. Is some sort of detailed peak /load shape of interest in the new
world? What about power factors? Is the forward and backward reporting of
curves rather than points of measurement the future of smart metering?

questions for discussion
All,
David Holmberg and
I had a great conversation today on the scope of EI (which will hopefully feed
into section under discussion). I’d like to open up some of my ideas and
get your feedback before I propose a few paragraphs for the scope section.
I’d
like to look at the scope from a B2G interface point of view and the questions
I suggest we try to answer are:
What information do the buildings need from the
electricity grid?
What information does the electricity grid need
from the buildings?
Buildings’ need from the Grid:
-
Electricity prices (various forms such as absolute, relative,
level, etc)
-
DR contract parameters – excluding direct load control: A
contract can have the following parameters:
- Issue
time, start time, end time
- Within
the start time and end time there may be a request from the grid for load
reduction (%, absolute, relative, etc) (or load increase - when there is too
much generation)
-
Power quality (Do we care how “good” the power we get from the
Grid? Probably! What are the indicators to be communicated to a building?
- Location of the resources needed
Grid’s
need from buildings:
- Measured
(current, historical) demand
-
Predicted demand
-
Available DR (over next 24 hrs?, 1 week?)
- Location identifier (meter, address, grid location
indicator?)
I welcome
your comments. All of the above assumes that the meter is the demarcation
point. And just to add, the expansion of this to DER can be again categorized
as on the utility side and on the building side but should be a super set.
Sila
