摘　　要：在双碳目标要求下,针对青岛某区域的供热问题提出了海水源热泵、燃气锅炉、水蓄能互补系统,建立设备供能模型,考虑经济性和环保性目标,采用建模工具和求解器对多能互补系统机组组合问题进行求解分析,得出供暖季下负荷率为100%,75%,50%,25%的典型日运行优化结果,并对优化结果进行经济性、节能性分析。结果表明,该互补系统与单一系统相比碳排放量较低,其优化控制策略可以调节冷热负荷与机组出力相适配,减小电网压力,与传统运行策略相比经济性、节能性更高。Under the requirement of “double carbon” target and aiming to solve the heating problem in a region of Qingdao, this study proposes a complementary system which consists of seawater source heat pump, gas boiler and water storage. Equipment energy supply models are established by putting into consideration the objectives of economy and environmental protection. Modeling tools and solvers are used to analyze and solve the problem of the multi-energy complementary system unit combination, and typical daily operating optimization results are obtained, with load factors being 100%, 75%, 50% and 25% during the heating season. The analysis of the economy and energy saving of the optimization results are also carried out, showing that the complementary system has a lower carbon emission than a single system, and the optimal control strategy can adjust the cooling and heating loads to match the output of the units and reduce the pressure on the grid, which is more economical and efficient than the traditional operation strategy.
