Due to the fuctuation of wind power output and the "heat to power" mode in the heating period, the wind abandonment phenomenon in coastal areas in winter is increasingly serious. From the perspective of integrated energy system in coastal areas, this paper frst builds an optimal operation model of integrated energy system in coastal areas with the minimum daily total operating cost and the minimum amount of abandoned wind, and constrains the output condition of the corresponding equipment. Then, the mechanism of the adjustable characteristics of seawater desalination load is analyzed, the adjustment range of seawater desalination load is calculated, and the integrated energy system optimization operation method in coastal areas is designed considering the desalination load. Finally, the winter scene of a coastal area in northern China is taken as an example to conduct simulation verifcation. The results show that the total daily operation cost of the system is reduced by 4.6% and the wind power consumption rate is increased by 2.87% after considering the load regulation efect of seawater desalination, which efectively verifes that the integrated energy system operation strategy designed plays a signifcant role in improving the system operation economy and promoting the consumption of new energy.
