Hi, I am working on a PV system model with battery and I need your expertise on an issue. When I check the power value of my pv panel with constant irradiance and battery, the power values for both of them are fluctuating. I check the output from the charging and discharging terminal, it seems that it is charging and discharging at the same time, would this be the cause for power flucuation? Would the PWM generator cause the PV panel's power output to fluctuate?
just a wild guess, try playing with the solver settings.
try a fixed step solver, with small time step (1e-6).
let me know
Baraa Mohandes I am not experience with using the software, may I know how do I use a fixed step solver?
ctrl + k
solver
also check simulink documentation on how to change solver settings
Baraa Mohandes I tried with Ctrl + k but there wasnt anything. Searching in the library browser also wasnt there, is there any other way to get the solver?
Sorry, it's CTRL+E
or from the menus, go to menu "Simulation"
in the "Simulation" Menu, go to "Configuration parameters"
and on the left side column, check out the "Solver"
In your case, you can also double click on the "Discrete" block at the top left corner of your model and play with the settings.
Simulink library is for simulink blocks and models, not settings.
