Control of a biogas co-firing CHP as an Energy Hub

This paper presents a method of utilising the Energy Hubs concept, a whole systems approach, to optimise and control the input fuels to a given load or demand. A Raspberry Pi was used as a controller for a co-firing Combined Heat and Power (CHP) generator. The control of the two fuel inputs was validated. It was found that the methodology can minimise the desired objective effectively. In addition, the control arrangement was found to be suitable for controlling an industrial valve which regulates the fuel input to the CHP generator.
