Optimal operation model of seaport integrated energy system with seawater desalination for hydrogen production and thermal inertia

针对大型海港综合能源系统存在的多类型能源需求难以平衡的问题,提出了一种考虑海水淡化电制氢和热惯性的海港综合能源系统优化运行模型。充分发挥海港的地理优势,引入海水淡化装置和电解水制氢系统作为综合能源的可控负荷,实现风光发电的就近消纳,并为海港提供水负荷;考虑热负荷的惯性和人对温度舒适度的约束,灵活调整供热负荷的输出,进而构建了以日化综合最小用能成本为目标的海港综合能源系统优化运行模型。仿真分析表明,所提模型能够在满足海港内负荷需求的基础上,减少系统的运维成本、购能成本、碳排放成本以及弃风弃光成本。

Aiming at the problem that it is challenging to balance the demand of multiple types of energy in large-scale seaport integrated energy systems,an optimal operation model of seaport integrated energy system considering seawater desalination for hydrogen production and thermal inertia is proposed.The geographical advantages of the seaport are fully exploited,and the seawater desalination equipment and electrolytic water hydrogen production system are introduced as the controllable loads of integrated energy to achieve the nearby consumption of wind and solar power and provide water loads for the seaport.Considering the inertia of thermal load and human constraints on temperature comfort,the output of heating load is flexibly adjusted,and then an optimal operation model of the seaport integrated energy system is constructed with the objec⁃tive of daily integrated minimum energy cost.Simulation analysis shows that the proposed model is able to reduce the operation and maintenance cost,energy purchase cost,carbon emission cost,and wind and light abandonment cost of the system on the basis of meeting the load demand in the seaport.
