Dear Madam I hope this comment finds you well. I wanted to express my gratitude for the fantastic content you've been sharing on grid-connected inverters using Simulink. Your explanations have been invaluable in my learning journey. I've successfully simulated the model you provided, but I'm currently facing challenges in achieving stable outputs for both active and reactive power. Specifically, when attempting to control just reactive power, there is active power present, and vice versa. Ideally, I'd like to independently regulate active and reactive power outputs without any cross-coupling. Moreover, I aim to have stable outputs that change based on the reference power without fluctuations. I've noticed that in academic papers, the output of inverters is often depicted as constant. I'm curious about the techniques or considerations that lead to such constant outputs. Your expertise and insights would mean a lot to me as a student navigating these topics. Thank you so much for your time and for sharing your knowledge.
hello, madam. thank you so much for the tutorial. i want to know how can we calculate the PI parameters; and are they the same for all reference values ( like instead of -200 we take -10). i am working in Z domain .
The PI controller has been designed on gain tuning technique. Choose a small value of Kp and set Ki to zero. Keep increasing the value of Kp until you reach neutral stability. Thank you for the support.
Hello, if you are operating in islanded mode, you can check this video where both voltage and current are controlled th-cam.com/video/6pNPnkvmAMI/w-d-xo.htmlsi=khdY1gFmRWtmnvQM
@@pmctech1415 Okay Thank You Soo Much, Let me see this Video and If I have any queries I will comment in that Video. Actually I want to make the Grid Forming Controller in which voltages are controlled your this model is the Grid Following converter. So if you have any model of Grid Forming Converter or any Video please let me know. Kind Regards!

Great work thank you so much 🎉
You're welcome 😊
@@pmctech1415 Do you have a contact number? Can you share it? I have homework on Matlab simulation.

Thank you for the video please I can't find the same results as you please detail a little at the end of the video. THANKS
Hello, Thank you for watching. Share the model on pmctech1415@gmail.com
Hello, i follow your steps but my inverter current isn't a perfect sine wave. Can you help?
Mine too
Hi thanks for this great video, FOR THE FILTER DESIGNING Pn is 100000, VpH is 800 WHY THE RESULT IS 20?
Hello, thank you for watching. Kindly check the formulas in the description box.
Thankyou very much.🙏🙏
You're most welcome
What is the efficiency of the inverter?

From where did u derive the equation for ripple current and Vdc

Can you please provide the inverter and grid design?
I don't understand your question clearly
@@pmctech1415 how did you choose the voltage value ? Was it randomly taken?
will you have reference books?
Kindly check the description box for some of the references used.
Hi mam. Can you please provide the inverter and grid design? 😊
Hello, sorry, I don't clearly understand the question
How I can convert this Current Controller into Voltage Controller ? To control output Voltage instead of Current

Hello @waqasqaisar8808 i would love to find out if you managed to successfully model the grid forming inverter?
Is this grid forming or grid following?
@arifanwar9373 No, it's not
Mam, the output of PLL PI is non zero?
Hello, the output is a sawtooth signal ranging from 0 to 2pi
thank you very much
You're welcome 😊 🙏
❤❤❤❤
How did you calculate reference Id and Iq as -200?
Hello, it was not calculated, but just set/estimated
@@pmctech1415How should it change if I want to change the grid voltage?
@abrarfuad2319 You can just try out different values and observe.
@@pmctech1415 ok mam thanks a lot
@@pmctech1415 Ok mam, thanks a lot
Which library have u used?
Hello, It's Simulink library
@@pmctech1415 is simscape or other toolbox has been used?
@@muttakihasan3264 Simscape
Can you provide the matlab modeling of this.
Or if any one made this model please share
