Abstract

Recently, there are problems with environmental issues such as global warming and depletion of natural energy resources. Photovoltaic systems as renewable energy have been attracting attention. The output power of the photovoltaic system changes steeply, because solar radiation intensity and temperature depend on the weather. In the conventional photovoltaic systems, the surplus power excluding the power consumed in the load flows back to the grid. Therefore, the fluctuation in the output power of the photovoltaic system have an bad influence on the grid. This paper proposes a novel hydrogen-storage distributed generation system using unitized reversible cell integrating the fuel cell and water electrolyzer for smoothing the reverse power flow. The hydrogen-storage distributed generation system is modeled and the computer simulation is implemented. It is clarified that the proposed system is valid for leveling the power flow back to the glid by two evaluation methods.
