[LDES-technology] [LDES-coremodel] Draft abstract for PVSC

[Sarah Kurtz]

Hi, Noah,

Thank you for the useful comments.

I neglected to give key information:  This abstract is limited to 3 pages.

You’ve made a lot of good suggestions.  We should talk about how to coordinate - maybe at our meeting on Friday?  I haven’t sent the agenda yet for that meeting - I have some other questions I’d like to discuss on Friday, but we should have time to do both...

Hi Sarah,

Thanks – depending on your vision for the paper or other output venues, we could add some more detailed information technology options to meet that seasonal demand and relate that with the effects of higher/lower efficiency of charging/discharging for storage devices – which will impact the amount of storage discussed in the paper.

I have a few comments that I hope may help as well just as friendly suggestions – though I’m not sure about the space limitations for the methodology in this conference. For instance when using the phrase “straightforward approach” the methodology could be communicated a bit more clearly as that introduces ambiguity and lacks specificity. My understanding is that the analysis uses state-of-charge of storage+solar+wind as a way to meet resource adequacy. That could be written more explicitly. One question that may emerge where this approach differs from others is that solar, wind, and storage are effectively supply rather than changing the demand as is done in prior studies. Other minor point is does this study define resource adequacy as matching supply with demand or having some extra margin? The phrase inadequate resource adequacy sounds redundant to me.

The other area that could be clarified and introduce questions is the statement “to simulate the grid of the future, the thermal, imports, and nuclear data were replaced with added solar generation.” I think many reviewers would want to know about the calculation on how that generation is replaced, i.e. on a capacity basis or on a generation basis? How many GW of solar to match existing “firm generation?” What is the capacity factor of the solar installed? It might help to include the installed solar/wind in a table or text. That would greatly influence the storage needed and results. It could also add some more specific information on how much solar you need to decrease the reservoir from 7.3 TWh to 6 TWh. It could be a trivial clarification to explain how much solar is included in these scenarios, but would be important so that someone can understand how much solar we are talking about and interpret the model.

Just a few of my thoughts, so given the conference deadline don’t feel obligated to answer and maybe some of these questions are off-base, but I think some similar issues may come up in an expanded literature version of this paper.

I also have a student that is developing a similar but different load duration + screening curve analysis for North Carolina where storage manipulates the load – if it would be interesting in the future (which is beyond) the code is well suited to read FERC 714 data and could compare results with California. That is probably a separate discussion, but could be good to compare at some point.

Fantastic start.

Some edits attached, and Kenji and I could work on-shore vs. off-shore electricity and H2 integration...

Here is a draft of an abstract that Abido has been working on for submission to the PVSC. We welcome your comments. We are trying to decide who should be on the author list - if you would like to be listed as an author, please let us know along with what contributions you would like to make as we take this toward the final paper. We plan to submit a longer paper to a peer-reviewed journal while keeping a short paper in the PVSC proceedings.  Please return your comments by Jan. 24. sorry for the short turn around - if you need more time, we may be able to submit a revised version a little later.
