风制氨与电网、氢气供应链的优化配置--以内蒙古为例
Optimal Configuration of Wind-to-Ammonia with the Electric Network and Hydrogen Supply Chain: A Case Study of Inner Mongolia
摘要：
将风能转化为氨（WtA）已被认为是提高风力发电利用率的一种有前途的途径。本文提出了一个通用的优化配置模型的WtA在网络层面上，以最大限度地减少氨生产成本，通过优化的能力和位置的WtA设施，包括风力涡轮机，电解槽，氢气罐和优化供应模式之间的区域。具体而言，考虑了风资源的时间波动特性、氨合成反应器的操作灵活性和运输距离。三种典型的供应模式，即，考虑EN最大能源运输能力和HT日运输距离（500 km），分别采用本地WtA、基于EN（电网）的WtA和基于HSC（氢气供应链）的WtA，并结合EN和HT（氢气卡车拖车）两种能源运输方式。以内蒙古为例，验证了模型的有效性和意义。分析了上述重要因素对WtA设施最优规划容量和最优能源运输方式的影响，为WtA设施配置提供了指导。经济分析表明，内蒙古WtA的平均LCOA（氨的平准成本）约为0.57欧元/千克，与CtA（煤制氨，0.41欧元/千克）相当，设施的容量成本降低了30%。
英文摘要：
Converting wind energy into ammonia (WtA) has been recognized as a promising pathway to enhance the usage of wind generation. This paper proposes a generic optimal configuration model of WtA at the network level to minimize the ammonia production cost by optimizing capacities and locations of WtA facilities including wind turbines, electrolyzers, hydrogen tanks and optimizing supply modes among regions. Specifically, the temporal fluctuation characteristics of wind resources, the operation flexibility of the ammonia synthesis reactor and the transport distances are considered. Three typical supply modes, i.e., the Local WtA, the EN (electric network)-based WtA and the HSC (hydrogen supply chain)-based WtA, combined with two energy transport modes including EN and HT (Hydrogen truck trailers) are included with the consideration of the maximal energy transport capacity of EN and transport distance per day of HT (500km). Real data of Inner Mongolia (a typical province in China with rich wind resources and existing ammonia industries) is employed to verify the effectiveness and significance of proposed model. The effect of above significant factors on optimal planning capacity of WtA facilities and optimal energy transport modes is analyzed, which provides guidelines for WtA configuration. The economic analysis shows that the average LCOA (levelized cost of ammonia) for WtA is approximately 0.57 euro/kg in Inner Mongolia and comparable to that for CtA (coal-to-ammonia, 0.41 euro/kg) with a reduction of 30% in capacity cost of the facilities.
