[LDES-technology] CEC LDES project - May 14

[Sarah Kurtz]

Updating our agenda for our May 14 meeting (coming up shortly):

• Preparing for E3 meeting: What questions do we have for them?  (Interesting for us to think about what actions we will take if they say that they aren’t addressing any of these items) The meeting with E3 has been moved to Wed May 19 at 4 pm
• Reviewing authorship guidelines – do we all agree on what contributions merit authorship and what contributions merit some other acknowledgment?
• Review list of papers we are developing
• Review upcoming deliverables

I think this will be a good time for a high-level discussion about our directions and hope you’ll be able to come and bring your thoughts. My goal is that each student has at least one first-author paper in the works and I expect that each of you will also have a couple of other papers you will be coauthors on.

Here is a list of questions for E3 that Pedro and I put together as a starting point. We may not have time to ask E3 all of these questions – I expect that they will start with a presentation.

May 14 meeting: Preparation for meeting with E3 – May 19th meeting

Timepoints strategies –
• Can we select the number of timepoints per day?
• Can we select which hours?
• Can we select which days?
• Can we select a variable number of timepoints per day?
• Can we easily run the simulation in a two-step mode doing the capacity expansion with large time step and dispatch with smaller time step?
• Will they provide full 8760 data? (shapes and load data – also hydro, and other things)
• Will they provide full 8760 data for more than one year?
• If so, can we select which year?
• Are they considering weather (shapes/loads) projections for the future?

Hydrogen –
• Can we optimize the electrolysis?
• Can we build electrolyzers?
• Do they allow for $/kg value of hydrogen generation? Currently if I run an electrolyzer that eats up electricity and incurs cost, but I don’t think there’s any value associated with that hydrogen. Difference here is we need a curve that gives $/kg as a function of period and we need to be able to implement – which we can easily do by subtracting from the operating costs.  Would they allow negative numbers?  Electrolyzer is a “load” not a generator.
• Have they modeled hydrogen storage as electricity-in-electricity-out.

Demand management –
• Have they added any new types of demand management?  If so, what?
Question for us? If they say “no” will we take action?

CSP –
• Have they modeled storage for a CSP plant?

New storage options –
• How many new storage options are they including?
Our action: we should attempt to put together a model for each of the companies – that should start soon.
• Have they added idle losses in the model? (Makes sense for 8760 modeling)
• State of charge handling for partial year?
