I cannot locate where the graph for the frequency is in the model called 24-hour Simulation of a Vehicle-to-Grid (V2G) System. I also need to see what impact the Electric Vehicles have on regulating the frequency.

Thank you in advance.

Hello Darko,

From your query, I can see that you are looking for ways to monitor the frequency changes during the 24-hour simulation as well as its impact from different components.

I am assuming that you are looking for frequency visualisation capabilities for the Fast Fourier Transform (FFT) algorithm being run to convert the signals into the frequency domain. Additionally, to see the impact of the Electric Vehicles on this frequency you can calculate the impedance of the "V2G_Regulation" block.

The Simulink model consists of a "powergui" block that lets you set and analyze different parameters of the simulation being run. Using the options of the block, you can visualise the frequency and calculate the affect on frequency. Please refer to the below screenshots to achieve the same for your use case:

1. Open the "powergui" block :
