Subject: Thinking about Models for Demand Response Interactions
|
Models for Demand Response (DR) Questions to tease out conversations on the correct
interaction patterns for Energy Interoperation Heard on the street: 1)
There are three kinds of DR: a. Pure
Price Information b. Price
and Contract Invocation (You remember that agreement we had to turn off the turboencabulator?
Well do it!) c. Curtailment
(The grid is going down. Its non negotiable that you…) 2)
Price and Product Description? That’s just Terms
and Conditions 3)
Financial markets are based around the multi-legged
product, i.e., a market that includes more than one product in the sale, and
the transaction is for all or nothing. For energy, this might mean a. Electricity
product sold with matching carbon credits to enable clean pricing decisions b. Green
credits stripped from one energy source and sold as part of another transaction c. Risk
and reliability are just line items, separately priceable. 4)
Even in a pure price world, we are going to need price
predictions for DR and storage to work. a. “Energy
will be more expensive tomorrow afternoon” b. Cheap
Energy will be available after 9:30 for the next 11 hours. 5)
For industry, long running process require long running
energy commitments a. I
want to buy this suite of products, x KW per interval for 15 consecutive
intervals before I stat the process. b. For
bids, I will accept all of the intervals or none c. Balancing
an early morning production run and an evening production run for two different
factories may result in custom pricing in a single market/locale When I am thinking about the model for DR, and the model for
Pricing/Product we plan to include in DR, I think about how to optimize for all
of the above statements. I think about simple data models that can be shared
with small devices. I think of complex models to interact with industrial
processes. I think of hiding the distinctions between DER, Storage, and DR. What is the right way to indicate price commitments over
time? A series of intervals? A price curve? How do I bid an energy use curve? What if I offer back a
curve that is cheaper on 6 intervals but more expensive on one? Can the consumer submit 4 usage curves for bids, and accept
the single one that best serves the needs of the [factory]? How do we transact
those offers / bids / deals? What can we learn about how to do this consistent with the financial
model of the “multi-legged deal” "When one door closes, another opens; but we often look
so long and so regretfully upon the closed door that we do not see the one
which has opened for us." -- Alexander Graham Bell
