Solid Oxide Fuel Cell Power Management Based on a Predictive Controller

At present, renewable energies play a preponderant role, because we are experiencing the depletion of fossil energy, especially, fuel cells. The basic principle of these batteries is based on chemical reactions, which explains their slow response, the progress of the control, which requires investing in this field so that the systems based on batteries reach maturity. In this paper, a new technique is presented for the control of the active and reactive powers coming from an energy production system based on an SOFC fuel cell. First, the system considered is presented containing an SOFC fuel cell, a PWM inverter and an AC load, the validity of these analyzes is verified when the energy production system is subjected to load variations with the use of a conventional PI and GPC controllers for a given load. Also when the load variation becomes faster, the results show that with the GPC control, the requested powers are almost identical to that supplied. By this work, it can both test the validity of this control, as well as the robustness.
