How to control PV both current and voltage

I need to control both I and V of a PV ,by using a boost converter with PI.Im able to control only the voltage.How do i control both current and voltage.

@Pranav Pillai, can you show the differential equations of the PV system?

By analyzing the equations, it maybe possible design a math equation for the control signal so that it transforms the existing PV system into a controllable system with the desired response.

You may do this via two cascaded control loops.

i) Outloop will have voltage control

ii) Inner loop will have current control.

Have a look at this example:

Look into the following subsystem for your reference: ee_solar_boostconverter_maxpowerpoint/PV Control/Constant Voltage

there are many other examples likewise. I hope it helps.

This is a fun game, and if you play it with some pals, you're going to have a great time. One of my very good friends who is currently employed at cookie clicker introduced me to this game, and I've had the opportunity to collaborate with him on quite a few occasions while playing it. It is really incredible!
