Great video , sir ! Keep Going ! I have only one suggestion: it would be perfect if you could provide the references of materials/papers you used while conveying the information. Would help to those who like to dive deeper into the stuff

bahut bahut Dhanyavaad, youtubai mein mera dost, main iraak se hu

Very well explained and very helpful video keep making such videos

Wow, thanks for video man. Learnt a lot there

This very helpful. thanks for sharing. I have a question . After inner PI , Vd and Vq are added , then why they are multiplied by and divided by VDC? Thanks alot .

At 31:50 you mentioned that it is almost 10 kw which is the MPP value at 1000 irradiance. BUT I think at 1000 irradiance the solar MPP is 100 kw NOT 10 kw. It means power loss is tooo much in this simulink model because we are getting 10kw instead of 100 kw. Am I right ?

Sir,there are errors showing because of the ports not connected on the bus bar.... How can i solve that??

just before adding Vd and multiplying it by 2 and dividing by Vdc, Can I know why did you add IQ after the PI control and also why the value of 0.0001 in its omega?

Hi sir, great work. What steps did you follow in order to tune the PI controllers?

Thanks sir more love and respect for you.

Informative video..Please do a video on Machine learning based MPPT control

nice video, you save one guy who anxious for graduation project. but I have a question yet, what is the principle of the (2/Vdc), I guess it's used to reduced ripple of Vabc

Hi, I've followed all the steps in your video and I don't get the same results. The input power from the solar panels oscillates too much and I don't know why? Please help 🙏

The VDC shown after simulation is going above 1000V in starting, wouldn't it burn the IGBT , can we control the starting response

sir, can you tell me which paper or book is used for this model..its very important for me

Can u explain how the Kp and Ki values are considered at least u can give me a reference to learn how to calculate Kp and Ki value for models

Thanks for your sharing, good luck 4 u

You mentioned that the grid voltage is 400 and during simulation you set it as 415V. Could you please clarify this point?

Thank you for the videos. I am trying to develop PV connected standalone system. can u tell me what are the changes needed?

Hello Sir You are making very informative videos . Can you please the concept of dual loop VSG with PV battery and Grid

Thanks for the video, please can you share any reference paper for this simulation?

Sir, please make a video connecting this 2 Stage 3 Phase grid connected solar inverter to ieee-15 bus radial distribution system

Thank you for Video. I tried the same but I did not get the current waveform and DC Link Voltage. Can you help me in fixing out.

Hello, sir, your video is very good and useful to me. I use 1MWPV, VDC = 2000V， Why is the result wrong? I need to adjust the parameters of PI controller? Can you talk about the design of PI parameters？thank you!

I have done the simulation, but output is not coming properly. I guess from solar PV, the Vdc voltage is not generating properly. Can you please help me regarding this. Thank you.

@techsimulator please sir tell that the controller which you used in this video has better performance than all other controllers or this system can be also be implemented by using other controllers with the better performance? please respond.

Sir, please make a video on practical implementation of control system using simulink to DSP controller.Sir, please make a video on practical implementation of control system using simulink to DSP controller.

where can we find those simulaton results ? do you have a site ? where i can read your paper

Nice Video. I learnt a lot . But I can find where did you get the values. can you share with us the name of the book from which you get the equations to calculate the values?

How did you design PI values, gain values, unit delay. Please explain.

Thanks for this video sir...

thanks for the effort, a question why you put 2/VDC??

Thank you sir .. kindly give the research paper related to this modeling @Tech Simulator

to design 10kw pv, what are the changes required for this system?

getting error after working on this for more than an hour. Provide the simulation file too please

I m getting error in alpha-beta-zero to dq0 and in its integrator in alphabeta part's....how to solve it .....I m not getting the output also.....

Very good work sir. Please I've implemented the exact model. My results shows that the currents increase when radiation is reduced. Please can I send you my model so that you could check it for me. Thank you

Hi, Is it possible to add Harmonic Spectrum of an Inverter, if we have the manufacturer given values, to the system we designed and get the THD for V & I done?

Sir, also please tell us how to generate fault into this system at the inverter side.

filter cap is 100e-6 then why did u take 1000e-6 in the gain?

Thanks a lot for this good work, I will try it.

Is the inverter used is 3 level multilevel inverter?

Hi, I hope you can help me out. I do have circuit but without converter and I need MPPT for inverter?I did well but showed error. Could you please help me

Sir can we use four wire VSI instead of two stage VSI for this project?

Hi sir! with this system i want to control it as a statcom by system will generate when load is on and system will not generate when load is off. Please suggest me. Thank you very much.

Sir kindly add a load at PCC and show how power share by from grid and pv with different loading conditions .

thanks for the video, why you set 600 voltage manually and don't use the Vdc before the inverter(there is no capacitor before the inverter)

Respected, if i designed same simulation for 10KW inverter then PI controller value need to be change or will remain same?

by changing the PV array parallel modules to 4 also the value of current peak is five hundred

Please, could you put the reference you are using in these simulation ?

@Tech Simulator Professor, I implemented the same program, I only had a problem with the shape of the current, can you help me, please?!

How did you design the RC, L and C value?

Sir can u plz tell me why we prefer wt of abc to dq0 block to give it the optput of pll

Hello, this video helped me a lot in my work. Thank you I got two questions for you, in hope you can help me: 1) I'm modelling a microgrid, with a 4kw PV array (2x9) can this methodology be used for this type of project? Only looking at Grid-tie mode, for power balance studies. 2) Can't get the boost converter to work with my parameters, voltage doesn't steady and keeps rising, any ideas? Peace!

where can I found the explanation of controller ckt for Pv inverter?

Why it is showing one dimensional vector with 3 element error in demux

Sir can u tell that if non linear load is connect in grid side so how to calculate harmonics for different loads?

thanks for video

Brother can u plz tell me how u take values of resister inductor and capacitor for boost converter

what are the challanges you faced in the project

Does this have bidirectional powerflow capabilities?

When i run it, it gives me errors on input/output ports of demux and mux, how did you fix that? can someone help??

Hello sir. I have done the same by following your steps but i don't get this results. Please help me by solution

Why the circuit is not working if the three-phase measurement at the grid side is used without labels? Could you please help?

Sir , i did the simulation as per you did. i can't get the result ..Please help me

Please, can you do parallel inverter and Droop control for microgrid ?

Pls share a video on how to integrate solar and wind with battery

Sir,please tell me which paper you refered please tell me sir it is very important

sir active power should 100 kw ?

Sir, that "wt" Of phase locked loop is coming error ( not of same dimensions" Plz help Sir, how to rectify the issue

How did you choose the PI rates? Thanks

Sir, thank you very much for making this video. I have followed almost all your video and they are great. Please, I have followed this video and modeled the system but am getting these two errors, " Error in port widths or dimensions. Output port 1 of 'PV_Grid_Connected/From7' is a one-dimensional vector with 3 elements. Component: Simulink | Category: Model error Error in port widths or dimensions. Input port 2 of 'PV_Grid_Connected/Alpha-Beta-Zero to dq0' is a one-dimensional vector with 1 element." Could you please tell me what am not doing right? I have tried debugging it several times but I cannot figure it out. Please, anyone else with such experience could help too. Thanks.

How much rated power we have to take for single phase inverter

Sir ,can u please make a vedio on bidirectional EV charger (VtoG n GtoV)?

Why current is sinusoidal coming before the LCL filter

hello sir, I m getting errors in this in the transformation blocks plzz help me out sir

My curret waveform is not like yours also the power is displaying negative values

Why it is showing error in port width or dimensions?pls reply

Its showing an error derivative state of pid controller

why you add voltage supply in last

Can you please make a video to use wind turbine pv togehter to charge a battery

I also created the same model, but my current wave results were not the same, what could be the reason. Note: I took the dc source as converter output

Why do you write Gain = 2*pi*50*1000e-6? How this 1000e-6 comes from?

Vdc should be 653.19 minimum by applying formula 2*sart(2)*v line to line/sart(3)

Hello sir, I've done the same simulation, but at last when i tried to change the irradiance data, the current didn't change. Could you tell me Why it was like this? Thank you so much.

Very good video! But i had copy everything you did, but my DC voltage is not oscilating among 600V, can you help me?

Hello sir. I have done the same by following your steps but i don't get this results. Please suggest me solution

Sir in this circuit if we want load how we connect

Sir smart meter related simulation nhi h kya

when i tried to run this it shows me an error error in port widths or dimensions. 'Output Port 1' of 'pv/From7' is a one dimensional vector with 3 elements. and in demux when i left the 3rd connection point empty again it show that the third one is not connected

Dear Sir, may I please request a copy of the work file? Thank you

You just draw things but do not give any explanation that why do you take a specific step. For example in Voltage and Current controller you have taken gain(2*pi*50*1000e-6) with Iq but didn't explain that why have you taken this and what is 1000e-6? Please explain

Why did u convert to alpha beta and then to dq and not directly?

how to do the reactive power control sir?

Nice video. However I am facing issues in obtaining the desired results.

Could you please upload interleaved boost converter with fuzzy logic controller

plz sir what's the difference between single-stage and 2 stages plz
