我国“碳达峰”、“碳中和”目标将加速电力系统向以风、光发电为主的高比例新能源电力系统的演变进程,保障电力系统灵活运行是高比例新能源电力系统转型的核心。氢作为一种清洁、零碳、多功能的二次能源载体,可与电能相互转换,并长期高效储存,在高比例新能源电力系统灵活性调节方面将扮演不容忽视的角色。系统分析了未来各阶段电力系统特征演变及灵活性资源需求,电-氢相互转换及氢储存技术,研究和展望了电-氢枢纽在大规模可再生能源电力系统中参与灵活性调节的应用场景。

关键词: 电力系统转型, 电制氢, 电氢枢纽, 系统灵活性, 应用场景

Abstract:

With China already committing to peak carbon dioxide emissions before 2030 and achieving carbon neutrality before 2060, the evolution to a high-proportion new energy power system will be accelerated. Ensuring the flexible operation of is the core of the power system transformation towards a high proportion of renewable energy. As a clean, carbon-neutral, and multi-functional secondary energy carrier, hydrogen will play an important role on the flexibility adjustment of a high-proportion renewable energy power system due to its ability to inter-convert with electrical energy and achieve long-term storage. This paper systematically analyzes the evolution of power system characteristics and flexible resource requirements at various stages in the future, analyzes electricity-hydrogen conversion and hydrogen storage technology, and studies and prospects the application scenarios of hydrogen participating in the flexible regulation of renewable energy power systems.

Key words: power system transformation, green power to hydrogen, electro-hydrogen hub, system flexibility, application scenario
