hi welcome to the pz engineering channel in this video we are going to show how to simulate
pi controller based on a voltage regulation of a pv inverter in matlab simulink software

this is our system and i'll go through each component here we have our pv array
40 parallel 10 series connected those are the parameters of our pv array
here we have our capacitor one is the value of our capacitor one
here we have our voltage measurement which goes to there here you have our universal bridge
there's the the inches and anything
this is the is the control part that triggers the universal bridge
and then this is the that comes from controller here we have our three-phase parallel and then we
have our three-phase parallel rc branch and here we have our three-phase vi measurement
and we have our load demand that's the voltage of our demand we should bring our low demand the
parameters are there here we have our control um our that from pv goes to the measurement and here
we have our v that comes from our vi measurement of our gain is a reference voltage here if our
pr2 phase three phase and here we have our our abc 2 deep transformation mark we can follow it
here we have our selector we select indicate which one and here here is open rvd and vq
it goes to our pi controller these are the values of our pi controller you can just follow
it step by step and this all of those components you can get from the live web browser
here are whatever happen our in any of our pid biw generator those are the values and however
that goes to the gate that triggers the inverter
and here we've got the power is in the 1 to the power minus 6.
those are the measurements is to scope to measure the output
now let's run our system
let's check our pv voltage and current
and let's just calculate the power output
now let's run again and reduce the running time
let's check the output power from the pv
and let's change our solar irradiation as you know it affects the output power
let's check the output voltage and current and as we change the ignitions solar addition
as you can see the power is changing
let's keep on changing our solar irradiation
let's check the hc output
let's keep on changing
let's just keep on changing it
