Great work thank you so much 🎉

Hello, i follow your steps but my inverter current isn't a perfect sine wave. Can you help?

How I can convert this Current Controller into Voltage Controller ? To control output Voltage instead of Current

[@pmctech1415]

Hello, if you are operating in islanded mode, you can check this video where both voltage and current are controlled kzbin.info/www/bejne/bKGxgaGhq9J0g6ssi=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!

[@ndapewakalunga7495]

Hello @waqasqaisar8808 i would love to find out if you managed to successfully model the grid forming inverter?

What is the efficiency of the inverter?

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.

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

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 .

[@pmctech1415]

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.

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?

Mam, the output of PLL PI is non zero?

[@pmctech1415]

Hello, the output is a sawtooth signal ranging from 0 to 2pi

How did you calculate reference Id and Iq as -200?

[@pmctech1415]

Hello, it was not calculated, but just set/estimated

@abrarfuad2319 You can just try out different values and observe.

Is this grid forming or grid following?
