Modeling and control of solar fuel cell powered hybrid power systems.

In this paper a modeling and supervisory control strategy for a solar fuel cell powered hybrid power system are developed for stand alone residential applications. Automobile power systems are increasingly in need of renewable and clean energy sources such as solar energy and fuel cells in the context of global warming. Local controllers for the photovoltaic wind electrolyzer and fuel cell unit. Usually the operating times for wind and solar systems occur at different times of the day so the hybrid systems are more likely to produce power when needed.

Simulations are performed to document the efficacy of the proposed power management strategy. In this paper modeling control and power management of hybrid photovoltaic fuel cells battery bank system supplying an electric vehicle is presented. This article investigates the feasibility of a photovoltaic fuel cell battery hybrid electric vehicle pvfchev via a model based approach and delivers two major original contributions. Hybrid system hydrogen storage model predictive control mpc power management solar and wind sources i.

The different parts of the proposed system have been firstly simulated separately and then the power management control has been used to coordinate between the three sources to supply the ev. In this paper a modeling and supervisory control strategy for a solar fuel cell powered hybrid power system are developed for stand alone residential applications. The power demand requirement of the fuel cell is translated into a current demand input by dividing with stack output voltage. Control strategy of the hybrid power system.

Regenerative cycle of fuel cell helps to dump excess energy from dc bus. Due to variation in output power of solar panel wind turbine and fuel cell diesel engine is also coupled to ensure reliable supply under all conditions. Pv array system wind turbine system fuel cell fc and diesel generator systems are used for power generation. The major advantage of a solar wind hybrid installation when used together is reliability.

Using ultra capacitors uc and photovoltaic pv panel together with a fuel cell fc system is a possible solution to provide sufficient power supplies for residential areas. Operating the fuel cell at different output power levels requires suitable variation of its input flow rate to be realized by the overall control system of the cell. Currently most of the energy demand in the world is met by fossil and nuclear power plants.
