Hello!..There are few things I wanted to ask...Can we add a boost converter into this and if yes can i control it with the same MATLAB MPPT function or do i need to make it separately..and how do you calculate the deltaD..for some you take as 0.125 and for some 0.01..like how do we know what to take!..

[@avibajgain5811]

Hi Mr. Naki, In the model, you used the MATLAB function of MPPT which is different than the one used in boost converter modeling. I would be grateful if you could give some ideas about it or share the function block. Thank you.

[@juw.2438]

Hi Naki, thank you very much for helping us. I would like to use this system to simulate a residential system with 10 PV modules in serie and 2 parallel strings. I've tried this but it's not working when i put less than 16 modules in serie. What do i have to change in this model to get a working system with only 10 modules in serie?

[@ginebro1930]

Hi Naki, i noticed you skipped the dc/dc conversion and/or energy storage, do you believe this is viable to implement? Since the inverter is basically a buck circuit, one should connect a lot of pv panels in series to get enough voltage, shading on one panel could impact the output considerably. The idea seems tempting for the costs though

[@nakiguler]

Hi, yes I believe and I know some implemented systems. As I remember(I am not sure), ABB inverters are working like this.

[@TheTomxo]

Dear sir, cok tesekkur ederim for your videos, I've been learning a great deal from them by redoing your models from the beginning. I happen to have difficulties attempting this one. I believe I'm sticking to your steps quite accurately but my final results are off, mostly my reference current seems to remain 0 at all time and my reactive power is sitting at maximum as soon as my irradiance starts.. My guess is that it comes from the MPPT algorithm but I happen to be beginning on the topic and honestly don't know much about how to fix, if you could assist me or point me toward where to find help it would be greatly appreciated. Iyi gunler dilerim!

[@nakiguler]

First of all, thanks for your interest in my videos. Please check the inverter control algorithm. To do this, add constant irradiation for PV(500W/w2). After that, add a constant instead of Iref. Then, start the simulation and increase the reference current constant step by step. If the inverter control side works properly, please let me know. Otherwise, please check the inverter control algorithm step by step.

July/aug-2017 , but facing some difficulties in designing the inverter control logic. Can you help me on that? Thanks in advance.

[@nakiguler]

I am sorry, I have no experience with this topic. What is the problem with inverter control?

[@Saikatmisrakatwa]

@@nakiguler In this system the inverter is connected in series with a non critical load and the whole system is connected across a critical load, and the system is fed by a intermittent source. To keep the voltage across the critical load constant, we need to trigger the inverter in such a way so that the inverter can supply required amount of active and reactive power. For this purpose I have taken single phase dq transform of the critical load voltage and line current and synchronized this with the load voltage using PLL , after that I compared the Vd with the constant reference voltage and Iq with zero( to make Id have the same phase as Vd, and have a good power factor), and then I have taken this two error signal and performed inverse dq transform to create the reference signal for pwm generation. But the system is not working properly. Is there any fault in my logic??

[@ginebro1930]

There are a lot of reasons why you would get less depending on your circuit, if you did something similar to this video, probably your cuadrature current Iq is not set to 0, else if you implemented the converter circuits they must be operating at a range where you can draw power from the batteries for example a dc/dc booster circuit could need more current that the batteries can supply during a certain point i mean peak current, a capacitor could solve that. The list goes on...
