Hello sir @Naki GÜLER i want to know how to switch from Constant current to constant voltage mode at 80% SOC . It should sense automatically and enter into CV mode from CC mode. I have seen that you had changed the value manually i want to done automatically.
Sir, How do you calculate the inductance of converter and the DC Link in front of the load. and where is there not a need to put a Capacitor after the inductor for limiting the voltage variation. What is the load current for this circuit, Iref or Ibat ? as i am doing a v2g application thus i am trying to use the DC link as reference, its it a wise choice to use it ?
Could you share how did you get the values of the integrator, capacitor, inductor? Why did you change the value of the sample time of the discharging PI?

I am struggling by connecting the 3P inverter and do not know the inductor, resistor and capacitor value at the output. In my system, I have PV, varying load and controlled generator.

Sir please upload a tutorial related to single input multiple output dc source where we can get different small voltage dc sources of our choice from a bigger value of DC source.
sir i am doing battery and PV mangement project , can the DC supply change to PV input directly? or need some converter to ensure the charging and discharging is functional
If you only want to charge the battery, you can directly connect the PV system. If you have a load, the design will change. You can use a converter for PV and/or you should control the battery power by depending on MPPT.
In general boost converters are using for PV system. Of course, you need an MPPT algorithm. The load should be connected to DC bus. You should control the dc bus.
@@nakiguler Sir, i am a final year student. I use the same software as yours but i didnt get the result of regenerative braking and i stuck at motor part. I did not know how to connect it. i would really appreciate if you can consider to guide me a bit regards the issues. Perhaps via email?
Hi Sir, I am a grad student of Electrical Engineering at NIU and I am doing a project on using Neuro Fuzzy logic in controlling a hybrid microgrid, can you please let me know how can I contact you for more help.
Can this take on the role of an MPPT Solar Charge Controller? If not, how can I find an MPPT Solar Charge Controller or the blocks to create it, in the library?
Youness Laazibi, because the voltage source is an infinity bus. If we decrease its voltage, the battery can not enough power to increase its voltage to the desired level. It is only a scenario, you may use a dc bus.
I would like to ask you if you do not mind, please. I controlled the voltage at constant level, and when I simulate the system, The voltage is kept constand SOC is at constant level, which is 75% The current is zero That wasin charging mode But, at the discharge mode The voltage is kept constant SOC decrease gradually The current is positive Is that correct
Thank you soo much sir, this video has been of great help. The video was totally understandable, but could you add an explanatory voice, cause that would speed up the work a little bit. It would be easy for the viewer also to do the modeling. but still, Very well explained. Kudos!!
I have 3 different scenarios for solar power, wind power and load demand. On the basis of these I want to create charge and discharge signal for battery. Like 1000 solar, 1000 wind and load demand which will be negative feedback to the summer then what should be the PI gains to charge and discharge battery??
The management algorithm may change by depending on your system. You should decide follows: - When the battery will be in charge mode? (I mean, the algorithm should contain SOC limits) - When the battery will be in discharge mode? - What is the emergency back-up limit? - When the battery is fully charged(100%), you should stop the charge.
Please check the working principle of the bidirectional converter. Some converters uses Diode, some of uses IGBTs. Because it is bidirectional it needs two IGBTs.
@@subhabhaskaran1827, Actually the control algorithm works based on current control. But outer loop changes by depending on charge or discharge. As you said, the load is a constant voltage part for discharge mode. While the system is in charge mode, the algorithm works based on critical voltage point. These two-part generate a current reference for the inner loop.
Hello, actually PID and MPC are different controller types. So, one of them uses system parameters (MPC), PID has a tuning procedure depending on converter dynamics. So, the implementation procedure of MPC is different from PID.

Thanks. Because of the battery has bidirectional power flow, the current may be negative and positive. The reference current determines the charge or discharge current.
To do this, you may need a DC bus. If you supply the inverter from the DC bus, power flow will be from battery and PV. It will require a management algorithm. Because the system should know the enable and disable times.
