Hi @Maman,

I understand that you want to model railway power substation with energy storage system that utilizes train regenerative braking energy. Yes, it is possible to do so. You need to identify and define the subsystems and components of said system before using Simulink toolboxes to model the system. Please refer to the following resources to get started:
