Demonstration of Maximum Power Point Tracking (MPPT) Using boost Converter in MATLAB - Method 1

In this video, i am explaining how do we implement MPPT in a boost converter. I mentioned 2 methods in the video, one method is demonstrated here using Matlab, and the other method will be explained in the next video. Feel free to post your doubts in the comment section.

Sir, In the coming videos please show PID controller tuning and selecting the values step by step. In all the videos you have given direct PI values that are good but while we are working on other inverter circuits we can't able to get the proper PI values. I hope we will get a good understanding of PID controller in the next video. Thank you for your videos and this channel will get a good number of subscribers in future because of this content which is not available in KZbin systematically. We always support you for your hard work.

I got the general principle. Some of the under the hood stuff in the blocks leaves me guessing. Flyback transformer with buck/boost converter.

Sir, thanks a lot for the tutorial. This is the best tutorials I have seen from this topic, thanks a lot for sharing! I am trying to analyze a specific PV panel (I'm using user-defined model and inputting module specifications). But I'm not getting the correct output. I think the main problem with the PV array is that the irradiance input is on W/m^2 but there is no input field to place the size of the PV panel. I tried to change the number of cells per module, but it doesn't work also. Do you have any idea how to work this out? Thanks!!

I think my copy of matlab 4 is out of date. And simulink was just being released when I retired. I am clueless as to what a PI block is, from usage it looks like a discrete time filter. I am assuming a PI block is a low pass filter. I understand the logic tree, and the discrete differentiation V and I, and the boast circuit just not the PI block.

[@tiwar87]

Thanks for sharing Doc! I only have a problem.. When I simule belong 750 in irradiance everything is ok but when I put 750 or more until 1000 in irradiance, the power curve begins to oscilate (I have been reviewed my PID and MPPT parameters several times and is ok), maybe you know why is the problem? Thnks in advance

[@tiwar87]

I solve the problem! The powergui in discrete time of 1us is relative small, i choose to put in 10us and it solves the problem!

[@ArvindRao33455]

@Tech Simulator I actually intended that even at low irradiances the boost converter should still be able to provide the requisite voltage. Suppose at 1000 Wm-2 I get an output boosted voltage of 600 V at 600 Wm-2 also I must get the same voltage however the power would be diminished. So what can I do additionally so that my boost voltage remains constant irrespective of the irradiance?

[@santoshjaiswar4907]

Hi bro aim doing this project for constant output voltage... please help me if know how to implement this ....if we decreases irradiance will output voltage decrease or remains constant?

[@mohcine3416]

Thanks a lot sir...I wish you to present the PSO method based MPPT.

[@TechSimulator]

I will try different methods

[@scr_scr]

Yes sir PSO we neeed

[@Dc_tech386]

One thing I don’t get is when the solar panels drop current because of clouds the maximum power will drop out leaving the voltage and the sensor will sense that maximum power is drop but the converter will still put up some current but not the maximum current to turn on the sensor and voltage will drop lower then the battery voltage and this will overtime distract the battery cell will lower voltage to the battery and I realize a lot of mppt or like this the moment the senor can’t sense maximum power the charging should stop

what about boost converter output voltage. Is it constant by changing the irradiance or output voltage is varying. If output voltage is varying who will maintain the constant output voltage.

[@TechSimulator]

this is only mppt demonstration. Not boost voltage regulation. in application where u use only booat converter with PV is to chanrge the battery. In that case battery will ensure a constant voltage at the output and boost act as current source.

[@gian9540]

Is there a reason why when having 1 parallel string with say 10 series connected modules the mppt tracker is not able to locate the correct maximum power. In fact in order to obtain the correct value I had to change the load resistance from 2 Ohms to a higher value. Do you know why this is happening? Thanks for your videos :)

[@TechSimulator]

basically we we never implement mppt when we have a constant load at the output of the converter. we need to have either battery or grid. this simulation is only for demo purpose, just to understand how mppt works.
