To plot PV characteristics with both varying irradiance and temperature simultaneously, you can use the following approaches:
Approach-1:
- Connect the 'PV Array' block to a "Controlled Voltage Source" and vary the voltage from the closed-circuit voltage to the open circuit voltage.
- Using the voltage and current values, you can plot the instantaneous power.
- To explore a similar example using Simscape Electrical Foundation blocks, enter the following in the MATLAB command window:
openExample('simscapeelectrical/SolarPVDCWithBatteryExample')
Approach-2:
- You can use "Solar Cell" block in Simulink. From MATLAB R2024b, you can now generate a digital datasheet for the "Solar Cell" block using a MATLAB live script.
- This script imports parameters directly from the selected "Solar Cell" block in your model and generates current-voltage (I-V) and power-voltage (P-V) curves.
- You can modify the irradiance and temperature values accordingly to generate the characteristics. For more information on this you can refer to below documenation link: htps://www.mathworks.com/help/sps/ref/solarcell.html
