Great video!! I only have a question, Why you put a gain of 2*pi*50*1000e-6 after the output of the controllers.
sir, in this circuit have given lvrt condition so that it help during the faults.
I have loved your videos....I am working in a 300kW PV system....followed your design to replicate it mine but I haven't found the desired results....can I share my work 😊....for some guidance if you don't mind?
@@annwanjiku5885 I am working on this system with 5 level NPC inverter. I suggest you first design the same system as suggested in video then amend this system according to your requirement.
@Tech Simulator…..Sir, why the reactive power is fluctuating so much at steady state?
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
Thank you for the videos. I am trying to develop PV connected standalone system. can u tell me what are the changes needed?
@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.
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?
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
Wow, thanks for video man. Learnt a lot there
Thanks brother
@@TechSimulator Thanks for this video pls is the specification of this work from any paper. Can you pls share me the reference paper where you got the system parameters pls. My email is Stephen.aleje@gmail.com
Hi sir, great work.
What steps did you follow in order to tune the PI controllers?
The VDC shown after simulation is going above 1000V in starting, wouldn't it burn the IGBT , can we control the starting response
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 .
Sir can we use four wire VSI instead of two stage VSI for this project?
Informative video..Please do a video on Machine learning based MPPT control
Thanks for this video sir...
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 can u tell that if non linear load is connect in grid side so how to calculate harmonics for different loads?
Thanks for your sharing, good luck 4 u
thanks
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 ?
Very well explained and very helpful video keep making such videos
Thank you
@@TechSimulator very nice.I have some question sir.is it possible to tie lined this in two areas,like two areas tie lined wind farm?
what i mean is.by duplicating this simulink and tie lined with each other
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.
I want to use two stage for a stand alone microgrid. Can I make use of the controler which you showed that worked for unbalanced loads and replace this control strategy?
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.
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
Please, could you put the reference you are using in these simulation ?
How did you design PI values, gain values, unit delay. Please explain.
to design 10kw pv, what are the changes required for this system?
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.
Sir can u plz tell me why we prefer wt of abc to dq0 block to give it the optput of pll
Sir,there are errors showing because of the ports not connected on the bus bar.... How can i solve that??
where can I found the explanation of controller ckt for Pv inverter?
where can we find those simulaton results ? do you have a site ? where i can read your paper
Sir, also please tell us how to generate fault into this system at the inverter side.
Thanks sir more love and respect for you.
Welcome
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
How did you design the RC, L and C value?
Brother can u plz tell me how u take values of resister inductor and capacitor for boost converter
thanks for video
Does this have bidirectional powerflow capabilities?
@Tech Simulator Professor, I implemented the same program, I only had a problem with the shape of the current, can you help me, please?!
Thanks a lot for this good work, I will try it.
hi sir ,can you get this results? Please suggest me solution,plesae help
👍
What help you need
@@TechSimulator hallo sir, I made the model in matlab 2019a but didn't get the same result, any suggestion sir?
@@TechSimulator I have built your two models,the single and two stage three phase grid-connected ,respectively，but the results are different from yours. current waveform can not be achieved.
Is the inverter used is 3 level multilevel inverter?
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?
In decoupled control algorithm, we need to consider the voltage drop across the inductor. In d axis, we add the voltage drop that caused by the q adis current. So the drop is Id*w*L. S0 0.001 is the value of filter inductor
@@TechSimulator oh I see, can you provide any pdf file of the article that is behind this whole concept so that it would be easier for me to understand. Thanks alot
Thank you sir .. kindly give the research paper related to this modeling @Tech Simulator
what are the challanges you faced in the project
How much rated power we have to take for single phase inverter
Hello Sir
You are making very informative videos .
Can you please the concept of dual loop VSG with PV battery and Grid
Sir , i did the simulation as per you did. i can't get the result ..Please help me
When i run it, it gives me errors on input/output ports of demux and mux, how did you fix that? can someone help??
Sir, that "wt" Of phase locked loop is coming error ( not of same dimensions" Plz help Sir, how to rectify the issue
You mentioned that the grid voltage is 400 and during simulation you set it as 415V.
Could you please clarify this point?
No, he didn't enter 415V. At first he was going to set it at 415V but then he corrected it by entering 400V.
Hello sir. I have done the same by following your steps but i don't get this results. Please help me by solution
thanks for the effort, a question why you put 2/VDC??
I think that's for reduce harmonic of the Vabc out but I don't have the exact math
hello sir, I m getting errors in this in the transformation blocks plzz help me out sir
how to do the reactive power control sir?
Sir ,can u please make a vedio on bidirectional EV charger (VtoG n GtoV)?
Sir,please tell me which paper you refered please tell me sir it is very important
Thanks for the video, please can you share any reference paper for this simulation?
Hi..... Please could you help me if you can
Is there anything you got about that?
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
Why the circuit is not working if the three-phase measurement at the grid side is used without labels? Could you please help?
With mine, the boost inverter work perfectly but I connect inverter and grid components, it doesn't work.
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!
You need to change a lot of things. First of all you need to start by rearranging Boost Converter parameters such as RC-RL values and duty cycle.
Sir kindly add a load at PCC and show how power share by from grid and pv with different loading conditions .
Respected, if i designed same simulation for 10KW inverter then PI controller value need to be change or will remain same?
need to be changed based on the switching frequency and filter parameters
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 🙏
bro its showing me dimension error at mux last mux which is connected to dq0 wt do you hve any idea
sir active power should 100 kw ?
Why it is showing one dimensional vector with 3 element error in demux
Why it is showing error in port width or dimensions?pls reply
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)
I DIDNT SET 600 v manually. That is controlled by the inverter
There is a capacitor at the output of boost converter, which act as the input capacitor for inverter
@@TechSimulator sorry I mean the reference of vdc is a constant value 600
Hi... I did the same steps but i didn't find the same résultats please could you help me or say to me how i can solver this problem... Thanks sir.
sir, can you tell me which paper or book is used for this model..its very important for me
did you get the info?
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!
1. Yes you can use this methodology for your application.
2. May be there is error pi tuning of the controller. Also check the designed values of inductor
@@TechSimulator thank you, that's good news. If i send you my file would you take a look? =)
@@TechSimulator I think the problem is in the PI controllers, but apart from trying out new values on the controllers i don't know how to fix them... how do you figure yours?

Can you please make a video to use wind turbine pv togehter to charge a battery
by changing the PV array parallel modules to 4 also the value of current peak is five hundred
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
i have the same issue , did you fix it ?
Did you got proper output? Bcz i am also facing the same problems
I have also done the same model but my booster converter is wrong. The current waveform is of different amplitude and out of phase with voltage. Anyone here to help me.
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

Same error for me also sir ..total 6 errors I got in that 4 are demux n mux only.kindly help me out in this
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.
Same issue did you got any solution?
sir please i need it but in powersim simulation can you contact me to explain how can i do it in powersim
thank you in advance
plz sir what's the difference between single-stage and 2 stages plz
Why did u convert to alpha beta and then to dq and not directly?
I implementing the pll using alpha beta voltages, that is why
Sir were did I get the design of inverter and converter?
already there in my channel
@@TechSimulator thank you sir
Why current is sinusoidal coming before the LCL filter
Both grid current and inverter current should be sinusoidal. But inverter current will have more harmonics compared to grid current

filter cap is 100e-6 then why did u take 1000e-6 in the gain?
That is not the capacitor value, that is the total inductance value. 500uH + 500uH = 1000uH
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.
I got the same issue before, and I solved it by dividing the signal using mux and demux, you should ignore the warnings about unconnected input/output ports.
@@fayest7739 pls help me . I got same problem
@@fayest7739 Do you know if there is a particular reason to have those unconnected inputs/outputs in the mux and the demux? My simulation is running, I'm just curious about the warnings. Thanks
