Analysis of control Scheme for Photovoltaic-Fuel Cell Hybrid Energy to Power Management abstract

This paper presents a control design for hybrid photovoltaic-fuel cell system (HPFCS). These stand-alone systems, power generation are installed close to the load and there are no transmission and distribution costs. The HPFCS is composed of a Fuel cell generator (FCG), a photovoltaic generator (PVG) and a supervisor associated to a DC Bus. A power management strategy is conceived to manage power flows. Priority is given to PVG as it satisfies the load requirements. To balance the power an FCG is used when the power provided by PVG is not enough. The DC bus is fed through a DC_DC converter. The PVG is composed by photovoltaic arrays interfaced to a DC bus through a boost converter. The most important issues in the connection of power PVG to the FCG interconnection is the voltage regulation at the point of common coupling (DC bus). A modeling study was performed for the proposed HPFCS components. A fuzzy supervisor is developed. In the other hand, a fuzzy voltage controller is associated to the boost converter in order to adapt the PVG voltage and another controller for FCG.
