Model and Operation of Electricity-Heat-Hydrogen Energy Station

Hydrogen is expected to replace part of the fossil fuels in the future. Distributed wind and solar power is possible to produce hydrogen as an important primary energy source in order to enhance flexibility in energy distribution. The object of study is electricity-heat-hydrogen energy station composed of distributed power, electrolytic hydrogen, fuel cells and gas boiler. The research is focused on the models of hydrogen production and consumption to get the relationship among electricity/hydrogen/heat energy. A form of circuit diagram is used in this study. In addition, this paper also analyzes the station's economical running simulation model based on minimizing overall operating costs. The results prove that this system is actually capable of improving the overall efficiency of energy distribution.
