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 ?

[@nazrulhakimi72]

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

[@nakiguler]

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.

[@nazrulhakimi72]

Naki GÜLER if i have resistive load, what converter should use? Does mppt also need to be connected?

[@nakiguler]

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.

[@subhabhaskaran1827]

Good sir ...the control strategy used is combination of constant current and constant voltage??

[@nakiguler]

​@@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.

Of course, it may need a different control strategy.

[@talhagondal4215]

Can you please explain how did we manage that ?

[@nakiguler]

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.

[@playwithstyle4275]

Hello sir, in this video it seems that you are using PID controller for the battery. Is it the same way to implement MPC for the battery?

[@nakiguler]

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.
