The photovoltaic simulator is designed to study the operation of a standalone photovoltaic system, independent of the mains electricity supply. It uses a photovoltaic panel to collect and convert incident solar radiation into electrical energy for users. The system’s optimal operation is ensured by a battery charge controller and an inverter.
The simulator allows users to analyze the system’s behavior based on the battery charge level, the power demand from users, and the panel’s position. It also provides insights into the effects of disturbances on the system, such as cloud cover or the failure of a photovoltaic cell. For proper functionality, the simulator must be connected to a PC (not included).
