摘要: 青藏高原广大边远地区受地理限制和气候因素影响,能源供给问题长期无法有效解决。考虑到当地气候高寒、光照充裕、负荷分散等特点,结合氢能无污染、零碳排、高热值的优点,提出了光伏储氢独立供能系统的基本架构,以实现高寒条件下热电负荷的综合供应。并建立了含电解槽、储氢罐、燃料电池的储氢系统热电联供模型,充分挖掘储氢系统热电联储联供潜力。在此基础上,进一步提出了光伏储氢独立供能系统的容量配置模型和优化方法,并通过算例对比分析了光伏储氢独立供能系统与现有的光伏蓄电池独立供能系统的性能差异。仿真结果验证了本文所提光伏储氢独立供能系统方案的可行性。研究成果有望为青藏高原边远地区分布式清洁供能提供新的思路和方法。

Abstract: 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.
