Hi Dr Guler, I have followed all your videos and read some of your research papers. I’m interested in the islanded PV DC microgrid with voltage droop control. Is it possible to access this Simulation anywhere? Thanks.
Hello, i have simulation of a single stage, single phase flyback inverter, feded by a pv array. The control is okay but the output current can't be in phase with the grid voltage, even i have a PLL controler but nothing works, with all the modifcations that i do current and voltage can't be in phase, current is lagging about 90 degrees, what can i do?? :(
Please help. I'm getting this error. Error: The sample time 0.0002 of 'PV_Grid/PID Controller/Integral Gain' at input port 1 is different from the sample time 1e-05 of 'PV_Grid/Sum' at output port 1. Consider inserting a Rate Transition block between the two ports. Alternatively, you can control the diagnostic action for unspecified rate transitions by changing the option "Multitask (or Single task) rate transition" on the Sample Time Diagnostics pane of the Configuration Parameters dialog box.
Dear Soumya Ranjan , I'm getting this error:- simulink can not solve the algebraic loop containing "PID controller 1/proportional gain" at time 0.837 using the trust region based algorithm due to one of the following reasons: the model is ill defined. It will be very grateful if you help me in this problem. Here is my mail id:- nshrimali20@gmail.com
Hi Naki! Thank you very, very much for this video. Just have one question if I could have some of your time. Why is the DC bus control reversed? i.e. the reference in the negative part of the sum and the measurement in the positive? Thanks again in advance.
if i wanted to change this for a 600V AC grid would it be a simple case of changing the matlab code from 380 to 600 or would this change every value in that has been stated here? any help would be appreciated thank you
Hi sir! with this system i want to control it as a statcom by system will generate when load is on (generate support to grid) and system will not generate when load is off (power will go to grid). Please suggest me. Thank you very much.
Thank you very much for this video and simulation tips. I was wondering if you recommend any paper for the Grid-Connected modeling in order to tune the PI Controllers...
Sir I have model the previous model battery charging controlled Pv - battery integration design, now I like to connect it with inverter circuit. How to do that sir?
How to change the power rating of the PV array i.e. if I want a 100MW PV plant then what should be the changes in the simulation parameters. It would be very helpful for me. Thank you Sir.
Thanks for this valuable video , please Sir could you tell us How did select the value of 3-phase short-circuit level for the grid to be 100e6 because If I change it to another value output power single will be unstable .

Thanks for this video sir. I downloaded the MPPT algorithm but my MATLAB version couldn't open it unless it is converted to an earlier version. I Have 2018b. Is there anything you can do to help please?
Thanks. To make a partial shading condition, solar panels should connect series and parallel. Then, different irradiations should apply to see the effectiveness of the control part. But you know it is not an issue for just control side. I may think about this for the next video.
Dear sir, have you done some simulation of the microgrid before including the pv, wind power and energy storage? Could you do one vlog about how to build the microgrid? Very thanks!
I have integrated bidirectional and battery with this model,When we change grid side voltage 380 to 415 then output of dc bus voltage is increased why it's so can you please explain. Or anyone who know this suggest me the way how to overcome this problem.

Thank you very much for your video. its very interesting. I follow step by step your simulation in Matlab Simulink 2017a but I cant get the same results as you
Hocam öncelikle ayrıntılı anlatımlarınız için çok teşekkürler. Mppt algoritması oldukça kararlı çalışıyor. Herhangi bir heuristik algoritmayla ilgili böyle kararlı bir MPPT yapılabilir mi makaleleri okudum genel olarak daha iyi olduğu söylense bile uygulamada ben başaramadım. Kolay gelsin
Thank you for the informative video. I have some doubts. Can you just explain the control logic i.e how did you go from current error to modulation signal? The way I usually do it is I use the current error to generate a reference voltage which I apply to the modulator to get the PWM signals. But in your case you directly go from current error to the modulator. Also shouldn't changing the bus reference affect the PI controller gains?
Hello sir, I am trying to do the same simulation with buck converter but getting some errors. Can you please suggest me what and all modifications that need to in this simulation
Hello, power control with the buck converter is hard for PV and MPPT. Because you should consume all generated power. I suggest that first try it just using a load, buck converter and PV.
Very hard work and accurate design. Thank you for your precious time and help.
Thanks 😊
