Modeling And Control Of Solar Fuel Cell Powered Hybrid Power Systems

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.

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

In this paper modeling control and power management of hybrid photovoltaic fuel cells battery bank system supplying an electric vehicle is presented. 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. 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. The power demand requirement of the fuel cell is translated into a current demand input by dividing with stack output voltage.

Currently most of the energy demand in the world is met by fossil and nuclear power plants. 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. Hybrid system hydrogen storage model predictive control mpc power management solar and wind sources i. Regenerative cycle of fuel cell helps to dump excess energy from dc bus.

This hybrid system is more economical since the size of the battery storage can be reduced. A small part is drawn from renewable energy technologies such as wind solar fuel cell biomass and geothermal energy wind energy solar energy and fuel cells have experienced a remarkably rapid growth in the past ten years because they are pollution free sources of power. 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. 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.
