🚨COMMUNIQUE N°0507/SCED/DG/ 2026.
Objet: A quoi sert-il de recruter 2500 magistrats,de les nommer et de les rémunérer sans les affecter? @Presidence_RDC @PrimatureRDC @JusticeGouvCD @NgefaGuillaume @TopCongo @radiookapi @7sur7_cd @actualitecd @justiceinfonet #SCED #RDC #JUSTICE
Whoever understands this.... will understand that #PGRR145 #PCLR framework I sponsored for #largeloadflex #speedtopower is derivative of and cousins with all of my work on #DERS in @ERCOT_ISO #SCED and that I find it very funny that 3 yrs ago I was solving #DER #powerwall @teslaenergy math and now I'm solving for @nvidia #AIFactories math
Enough acronyms to take a damn bath in, also.
@patwood3 😄
Okay so before #ADER was ADER we had this goofy name, Aggregate Injection Withdrawal Resource: AIWR. I killed THAT fast. I guess it could come back. But, you can enjoy the legacy name pictured on this marker board. 👇🏽
Anyway, a #DER #aggregation needs its own composite nodal shift factor, calculated as the weighted average of the shift factors of the electrical locations where its controllable MW actually sits. The weight should reflect the aggregate’s real dispatchable capability or telemetry by location, not merely the broad load-zone load distribution.
Aggregate DER dispatch should not be priced or dispatched using a crude load-zone average if the DER fleet is concentrated at specific electrical locations. This is important because as ADER grows (it will), we will need to consider concentration effects.
In the example:
Whole load-zone SF: -0.012
DER aggregate A+C SF: +0.15
DER aggregate A+B SF: +0.133
That means the DER aggregate can have a materially different and even opposite congestion relationship from the load zone as a whole.
DER exports versus imports:
For transmission congestion purposes, a DER export and a load reduction are both a net injection relative to baseline at that electrical location.
So if a device moves from importing 5 kW to exporting 5 kW, that is not merely a 5 kW change. It is a 10 kW swing in net injection at that node.
The congestion impact is approximately:
ΔFlow=SFlocation×ΔMW\Delta Flow = SF_{location} \times \Delta MWΔFlow=SFlocation×ΔMW
For an aggregate:
ΔFlowX=SFX×ΔMWX\Delta Flow_X = SF_X \times \Delta MW_XΔFlowX=SFX×ΔMWX
So the aggregate shift factor tells the grid operator whether moving that fleet up or down helps or hurts a binding transmission constraint.
The sign convention needs to be locked carefully, but conceptually:
If DER injection at that location relieves the constraint, SCED should value/export-enable it.
If DER injection worsens the constraint, SCED should curtail or dispatch it downward.
If the fleet is charging or increasing load, the congestion effect reverses.

Testing season is here! 📓 Remember, unauthorized devices (phones, watches, glasses) can invalidate tests & lead to legal action. Stay focused on your hard work! You got this! #SCED #FreeToFocus 🎓 @drmarlonthomas @Sabrina_Suber @richlandtwo

@SecGranholm when you came down to Texas a few years ago for a briefing on our #ADER dispatch program that runs like a power plant out of aggregations of residential batteries, the heart of the solution was also, Load Aggregations w/ net export pwr telemetry in #SCED.
@SecGranholm T/Y for the incredible S/O. #VPP for large load is Loads in #SCED. Instead of aggregations in the dispatch engine, it's an algo that solves for constraints at participating nodes w/ #VPP-like response auto-cascaded to enrolled Gen, then enrolled load. @MattZeitlin
1. "cost allocation is mad crazy"!
2. "BYOG /CLR" (the thing my firm sponsored in #PGRR134 = speed to power), is it good for rates!
Everybody is wiped. It is moving so fast. I get it. Here's a Substack to explain these issues in @PUCTX
