Pozdravljeni,

delam na domačem/študijskem projektu v MATLAB Simulinku in iščem nekoga [seveda za plačilo], ki se dobro znajde v Simulinku, predvsem na področju Simscape Electrical oziroma elektroenergetskih sistemov.

Projekt je povezan s priklopom trifaznega PV inverterja oziroma modela sončne elektrarne na IEEE 34-node distribucijski feeder. Trenutno imam že delujoč primer PV inverterja, kjer lahko spremljam delovno in jalovo moč, zataknilo pa se mi je pri pravilnem priklopu na feeder preko transformatorja in pri interpretaciji rezultatov.

Ne iščem nekoga, da bi projekt naredil namesto mene, ampak predvsem nekoga za usmeritev, pomoč pri debugiranju ali mogoče kratek klic, če ima izkušnje s tem področjem.

Je kdo tukaj že delal s čim podobnim:

• trifazni PV inverter v Simulinku,
• Simscape Electrical,
• IEEE distribucijski feederji,
• P/Q regulacija,
• grid-connected inverter simulacije?

Vsak nasvet ali usmeritev bi mi zelo pomagala.

P.S Oziroma, če poznate na koga bi se obrnil ?

Hvala.

Hi everyone,

I am working on my bachelor’s thesis. The professor gave me the following topic (translated from Slovenian):

“Maintaining the voltage profile of a distribution network in islanded operation using the solar power plant converter as a D-STATCOM device.”

The professor specifically requires:

• Select a suitable medium-voltage network model.
• Add solar power plants (3-phase inverters).
• Set the active power (P) and reactive power (Q) of the solar inverters so that in islanded mode the network does not exchange active or reactive power with the substation transformer (which is now disconnected).
• Then change the r/X ratio of the overhead lines and analyze how this affects the P and Q of the inverters.

I already have the complete IEEE 34 Node Test Feeder fully built and working in Simulink R2024b.
I have also opened the MathWorks example “Three-Phase 3 Bus Low-Inertia Microgrid Droop Control Example” and I know how to create masked subsystems.

What I need help with is:

1. How to properly build/modify the 3-phase inverter (from the droop example) so it works as D-STATCOM in islanded operation.
2. How to correctly connect these inverters into the large IEEE 34-bus model.
3. How to set the control (P and Q references, droop parameters, voltage regulation, etc.) exactly as the professor expects.

I am willing to pay for your time (hourly rate or fixed price per milestone – we can agree via DM). I can share the Simulink model and the exact professor’s requirements.
