摘要: 氢气作为未来的主要能源形式之一,在社会生产中得到了广泛利用。利用新能源大规模制取氢气是实现新能源消纳和能源清洁化利用的重要技术手段,针对大规模具有间歇性新能源制氢系统的优化运行问题,提出了一种基于电解槽启停特性的日前出力优化模型。考虑实时电价变化、多电解槽运行状态和新能源的间歇性,满足功率平衡约束和电解槽生产约束等约束条件,建立了以系统运行成本最低的制氢系统日前出力优化模型。采用实际的风光出力数据和等效氢负荷特性数据,构建了4个不同场景制定日前出力计划,结果表明:提出的优化运行策略能够实现系统的安全稳定运行,避免峰段电价大量购电和碱性电解槽的反复启停,降低系统运行成本,验证了所提方法的正确性。

Abstract: As one of the main forms of energy in the future, hydrogen has been widely used in social production. Using new energy to produce hydrogen on a large scale is an important technical means to achieve new energy consumption and clean energy utilization. Aiming at the optimization operation of a large-scale intermittent new energy hydrogen production system, a start-stop feature based on electrolyzers is proposed. Day-a-day efforts to optimize the model. Considering real-time electricity price changes, the operating status of multiple electrolyzers, and the intermittentness of new energy sources, and satisfying constraints such as power balance constraints and electrolyzer production constraints, a day-ahead output optimization model of the hydrogen production system with the lowest system operating cost was established. Using actual wind-solar output data and equivalent hydrogen load characteristic data, four different scenarios were constructed to formulate a day-a-day output plan. The results show that the proposed optimized operation strategy can realize the safe and stable operation of the system and avoid large-scale purchase of electricity and alkali at peak electricity prices. The repeated start and stop of the electrolytic cell reduces the operating cost of the system and verifies the correctness of the proposed method.
