| Summary: | Because of geographic limit and climate influence, the energy supply problem in remote regions of Qinghai-Tibetan Plateau has not been solved effectively. Considering of local characteristics of extended cold climate, abundant light resource and disperse load distribution, since hydrogen energy has advantages of non-pollution, carbon-free emission and high calorific value, this paper proposes a framework of solar-hydrogen independent power-supply system to realize heat-electricity comprehensive supply in extended cold areas. The heat-electricity united supply model of hydrogen storage system, containing electrolyzer, hydrogen tank and hydrogen fuel cell, is formed to make full of ability of heat-electricity joint stock and joint supply. On this basis, the capacity configuration model of solar-hydrogen independent power supply system is formulated and the optimization method is provided. By case study, the performance difference between solar-hydrogen independent power supply system and the current solar-battery independent system has been contrasted and analyzed. The feasibility of solar-hydrogen system independent power supply system has been validated, and the results are hopeful to provide new ideas and methods for distributed supply of clean power in remote regions of Qinghai-Tibetan Plateau. |
