考虑电、氢、氨市场的可再生能源电制氢合成氨系统多主体合作运行策略

Multi-Stakeholder Cooperative Operation Strategy of Renewable Power to Ammonia Systems Considering the Electricity,Hydrogen and Ammonia Markets

可再生能源电制氢合成氨(renewable power-to-ammonia ReP2A)系统中的各主体与市场,各主体间均存在交易,文章研究了ReP2A系统中各主体在合作前提下进行电、氢交易的运行策略。首先,建立电-氢-氨合作联盟并应用纳什谈判理论来保证公平合作。其次,采用交替方向乘子法求解整体利益最大化和电、氢交易谈判支付问题。最后,以蒙西地区某工程构建算例进行分析,仿真验证所提策略的有效性。结果表明,电-氢-氨合作联盟利用联盟内外价格差来牟取电、氢市场利润,同时,可再生能源发电站寻求下游主体达成合作关系能降低可再生能源上网电价波动所造成的利润风险;电-氢-氨合作联盟通过协作和资源整合可应对外部电、氢市场的竞争。条件允许时,应鼓励可再生能源电制氢合成氨一体化工程开工建设。

Trading activities exist among various stakeholders and markets in the renewable power-to-ammonia(ReP2A)system.This paper studies the operation strategy for electricity and hydrogen trading in the ReP2A system under cooperative conditions.To ensure fair cooperation,Nash negotiation theory is applied to establish an electric-hydrogen-ammonia cooperative alliance,and the effects of electricity and hydrogen trading on each stakeholder in the alliance are discussed.The alternating direction method of multipliers is used to solve the problem of maximizing overall benefits and negotiating payments for electricity and hydrogen transactions.Finally,the construction of a project currently underway in West Inner Mongolia is analyzed as a case study.The findings indicate that the electric-hydrogen-ammonia cooperative alliance capitalizes on the price differences inside and outside the alliance to generate profits in the electricity and hydrogen markets.Meanwhile,renewable energy power stations seek cooperation with downstream entities to mitigate the profit risks caused by fluctuations in feed-in tariffs for renewable energy.The results show that the cooperative alliance addresses external competition in the electricity and hydrogen markets through collaboration and resource integration.When conditions permit,the construction of integrated projects for renewable energy-powered hydrogen production for ammonia synthesis is encouraged.
