This paper presents an optimized advanced control technique for a grid-connected hybrid energy system (HES) based on a solid oxide fuel cell (SOFC) and a photovoltaic panel (PV) in a distributed power generation system. A classical full sliding mode control and a Fuzzy-PI sliding mode are proposed for a system operation and power management mode (UPC mode). The latter technique which is based on a combination of a classical controller and fuzzy artificial intelligence system is utilized at power and current adjustment stage. The fuzzy system gave the optimal gain values to the PI controller to get a better performance. The obtained results show that the optimized sliding mode control (Fuzzy-PI) is better than the classical sliding one in terms of power, response time, and robustness against disturbances in production and consumption energy.
