储氢一氢氧联合循环储能系统及应用案例分析

储能技术是解决清洁能源并网发电所带来的间歇性和波动性问题的主要技术之一，引入储氢系统与风电联合运行实现并网发电。系统以氢气作为能量转换中间介质，通过电解水生产氢和氧，将多余或不稳定的电能储存起来。在需要时再将储存的氢和氧通过氢氧联合循环发电的方式转换为电能，实现并网发电。系统易规模化、无污染，可最大限度地发挥清洁能源的发电能力，能量转换效率达到40％。选取江苏省某一风电场进行案例分析，根据风电场的真实日负荷运行曲线设定了氢氧联合循环发电系统的装机容量和相关运行参数，并对联合运行动态系统进行了案例分析，结果显示该储能系统可以将间歇性的风电转化为稳定的电力输出，从而实现大规模风电并网发电．是解决清洁能源并网发电瓶颈的有效途径之一

Hydrogen Storage and Hydrogen-Oxygen Combined Cycle Systems and Case Analysis

Energy storage system is one of the best solutions for variability and intermittence performance of the wind power connected to power grid. This paper presents a hydrogen storage system as a means of energy management, the power is stored as hydrogen by an electrolyzer set, and generates electricity to the power grid by hydrogen-oxygen enmbined cycle during the peak hours. The whole energy storage system is absolutely environmental friendly and efficient, it has been proved that the net efficiency could be achieved to be 40%. The presentation makes a case study f＇or a special wind power plant, the integrated energy storage system is designed, and the installation capacity of integrated system is set according to the wind daily load. It is shown integrated energy storage system can convert the intermittent wind power to stable power, which can be directly outputted to power grid. Theretore, the integrated energy storage system can be useful for mitigating the bottleneck of renewable power development.
