1. Context
As part of my energy modeling project, I developed a simulation model in Simulink:
A photovoltaic (PV) panel model based on the single-diode approach, accounting for irradiance and temperature effects.
the model generate time-domain outputs under standard test conditions.
2. Objectives
I need to extract the I–V and P–V curves of the PV panel for different environmental conditions:
Irradiance (G): 200, 400, 600, 800, 1000 W/m²
Temperature (T): 0°C, 25°C, 50°C
3. Current model status
The Simulink PV model includes:
Computation of Iph, Irs, I0
Equivalent PV cell circuit
Buck-Boost converter with MPPT and PWM control
Time-based curves: Pin(t), Pout(t)Inputs: Irradiance (G), Temperature (T)However, it does not currently output I–V or P–V curves directly.
4. Issues encountered
No direct I–V and P–V output
No voltage sweep mechanism to generate these curves
No variation tracking across different G and T conditions
5. Request for help
I’d appreciate guidance on how to:
Add a voltage sweep mechanism (controlled voltage source) to the PV model
Automatically extract I–V and P–V curves for different G and T values
Create a simulation script that loops over multiple irradiance and temperature settings
Export the results (ideally to .mat or .csv)
Thank you in advance for any suggestions or shared examples!1. Context
