摘　　要：为解决“弃风”和风电的跨季节调用问题,需要建设与风电配套的储能系统。其中氢储能系统由于能量密度高、储存周期长等优势,适合与风电系统耦合,进行大规模、长周期的能量转移。传统观点认为,由于不适应风电的波动性,固体氧化物电解池(SOEC)不适合与风电系统耦合。但最新研究表明,SOEC在快速波动的电力输入下仍可以保持运行稳定。同时.SOEC还具有可以进行共电解和可逆运行的独特优势。基于此,这里提出了一种与风电耦合的电-氢-产-热联供的综合储能系统,根据需求可以实现多种能量输出形式,既可以实现“弃风”的有效利用,也可以作为能源清洁高效利用的微网体系。The application of energy storage system is an efficient way to alleviate the problem of wind power curtailment and realize the inter-seasonal invocation of wind power.Due to the advantage of high energy density and long storage cycle,energy storage system by hydrogen is suitable for coupling with wind power system.The conventional view is that solid oxide electrolysis cell(SOEC) doesn’t match the wind power system with high volatility.However,the latest research has demonstrated that SOEC stack can maintain operation stability under rapidly fluctuating power input.In addition,the co-electrolysis technology and reversible operation help to expand the limit of SOEC.Based on these,a comprehensive energy storage system with output of electricity-hydrogen-production-heat is proposed.The system can not only realize the effective utilization of "wind power curtailment",but also can be used as a micro grid system for clean and efficient usage of energy.
