Before the project was started, there was an energy system integrator demonstrator. This demonstrator was purely software, there was no physical interaction possible with it. It demonstrated the energy system by simulations. The objective of this project was to design and built peripherals that represents the components of an energy system. During the project, four peripherals were made that represents a solar panel, a wind turbine, a load and a storage indicator. A hub is placed on top of the Raspberry Pi, all the peripherals are connected to the Raspberry Pi via this hub. The peripherals consisted of two parts a representation of the energy technology and a microcontroller to do the necessary signal processing. For the communication SPI protcol was used.
