Such a fun team NEST-VT meeting today! Thanks to Rebecca (PESGM), Mazen (IEEECDC), and Dakota (PESGM) for presenting their new works on PV curtailment, battery opti, and energysheds. Great to have visitors from @BurlingtonElec (Freddie), @VelcoVT (Dan) , and @vermontpublic (Lou).

Enjoyed learning about the rich backgrounds and great work being done by @uvmvermont colleagues from across disciplines at one of my regular faculty breakfasts.

I am thrilled to announce that I have been awarded the prestigious NSF CAREER award! I am humbled to be among the recipients, and am grateful for NSF's support of my research. I thank everyone who made this possible.

Introducing NEST-VT: Next-gen Energy Systems Team of Vermont. Great group of students, postdocs, and faculty working rigorously on practically relevant problems
Excited to work with new colleagues @SamCChevalier and @AMP_andey to scale up the impact of our power/energy research.

@theEnergyMads @florian_dorfler Swiss Sterling Pond 🤣 stop it.
Essex Junction, VT 🇺🇸 English
Taking a breather from Zurich city life and trying to see how how well die Alpen compare with the Green Mountains. Here is the “Swiss Sterling Pond” (aka Seealpensee). Thanks to @florian_dorfler for suggestion!

@netcapgirl @kyrib, sorry, but it’s time to rewrite your DCOPF feasibility paper for truly lossless AC networks 🤷 I’m sure the editors will understand!!

superconductivity so good
slay haha
zero resistance at room temperature
gang gang
yes yes yes so many use cases including ultra efficient energy transmission
thank you lopez
you’re right we do need to wait & see if these results can be reproduced
scientific method so good

🚨Join us! @SamCChevalier, @AMP_andey, and I are recruiting a post-doc for a new 3-year DOE Energyshed project at the intersection of T&D optimization, DER control, electrification, and energy policy. Exp. start: June/July 2023.
Description is available: bit.ly/energyshed

13 teams from 11 states will compete in the Grid Optimization (GO) Competition Challenge 3.
This challenge aims to develop software management solutions to address challenging power grid problems.

The third international competition on neural network verification (VNN-COMP) finished last weekend! Congratulations to the α,β-CROWN team (@huan_zhang12 @KaidiXu1 @ShiqiWang10) and all the participants! Full slides with more results: drive.google.com/file/d/1nnRWSq…

@PMoutis @Nuclearjunkie Imagine local electricity costs become a new criteria for choosing where to buy a house: gotta check the schools, HOA fee, property taxes, historical d-LMPS..😎😅
Israel 🇮🇱 English
@Nuclearjunkie No sane energy researcher (those in this thread included) considers "exposing end-customers to wholesale prices" as you frame it. These are nuanced opinions of people who actually understand the risk of disregarding the 'social welfare' role of electricity...
English
While it seems Jesse isn't quite advocating for full wholesale market exposure, the number of people in this thread who seriously are is horrifying.
Jesse D. Jenkins@JesseJenkins
We need to do better than fixed period time of use rates. Dynamic, cost-reflective rates &/or super discounted automated load management programs are needed to unlock real economics of electrification + avoid billions in wasted/poorly utilized capital investment in grid capacity.

V sad to see the CAISO battery fleet discharging during peak solar production because price is above cap. The fossil fleet has more juice and when the sun goes down the batteries will be dead

The CORE Systems Lab at UVM (madsalma.github.io) is very excited to be recruiting multiple creative+hard-working PhD students to do R&D at the intersection of optimization and control in power/energy systems.
See attached description for one GRA. Other opportunities too.

@kyrib @priyald17 Yeah me too..

1) DC OPF to dispatch gen -> inaccurate estimation of flows
2) AC PF is run, which doesn't have explicit constraints but yields actual line flows
Possibly resulting in flows violating limits
Even if we move to dynamic line ratings...how are these actually accurately enforced?
English
@kyrib @priyald17 I only say “bad” because DC3 was intended for a learning-based approach, which will surely outperform the DCOPF in step 1 :-)
English
@kyrib Here’s a (bad?) idea:
1. DCOPF
2. ACPF
3. Identify inequality violations
4. Use @priyald17’s cool DC3 (arxiv.org/pdf/2104.12225…) to iteratively push PV setpoints in directions which lower violations, but “along the manifold of points satisfying [ACPF] equality constraints.”

@theEnergyMads Glad to hear rumors of your demise have been greatly exaggerated :-)

🥹Thanks, Sam, but I am not dead. Just moving timezones. Thanks for the fabulous conversations, great times, and our one accepted @ieeecdc2022 paper together on first try 🇩🇰🇩🇰🇩🇰 På gensyn!

Tremendously sad to see this whiteboard message from @theEnergyMads today. It was beyond fantastic having him @DTUpower over this last year!! I guess you can have him back now, @uvm_ee..
