| 氢储能具有零碳排放、电热气联供等诸多优点，有望成为实现碳中和目标的重要支撑技术。针对工业园区综合能源系统的电热气负荷需求特点以及低碳化发展的总体需要，提出了一种以氢储能作为多种能量形式转换枢纽的低碳园区综合能源系统架构，在分析氢储能单元电热气多能特性的基础上，建立了氢储能多能联储联供模型；进一步地，以投资运行成本以及碳排放为优化目标，提出了园区综合能源系统氢储能单元优化配置模型。基于实际算例分析了清洁能源发电及热电负荷特性、碳减排政策、氢储能投资成本等关键因素对综合成本及碳减排目标的影响，验证了通过配置氢储能降低园区综合能源系统供能成本和碳排放的可行性，并指出了其典型的适用场景。 |

| Abstract: |
| Hydrogen energy storage has many advantages, such as zero-carbon emission, electricity-heat-gas combined supply, and so on, and is expected to become an important supporting technology to achieve the goal of carbon neutral. According to the electricity-heat-gas load demand characteristics of IES(Integrated Energy System) in the industrial park and the overall need of low-carbon development, the framework of low-carbon park IES with hydrogen energy storage as the conversion hub of various energy forms. Based on the analysis of electricity-heat-gas characteristics of hydrogen energy storage unit, the multi-energy combined storage and supply model of hydrogen energy storage is established. Furthermore, an optimal configuration model of hydrogen energy storage unit in the park IES is proposed with investment and operation cost and carbon emission as its objective. Based on a practical example, the influence of key factors such as the characteristics of clean energy generation and heat-electricity load, carbon emission reduction policy, investment cost of hydrogen energy storage, and so on, on the comprehensive cost and carbon emission reduction goal is analyzed. The feasibility of reducing the energy supply cost and carbon emission of park IES by configuring hydrogen energy storage is verified, and its typical application scenarios are pointed out. |
