Abstract: Facilitating the "dual carbon" energy strategy, will surely usher in a new power system with new energy as the main power source. The bottleneck of large-scale wind power grid integration needs to be broken. This paper proposes an optimal scheduling strategy for desalination unit clusters with the goal of eliminating wind. First, the operating characteristics of the desalination technology is taken into consideration, and the relationship between the energy consumption, water production, and water demand of the desalination unit and the temporal and spatial changes of the water level of the water storage tank is modeled. Then, combined with the operating boundary of the desalination system, with the goal of maximizing the elimination of wind and abandoning wind, a desalination cluster optimization scheduling model is constructed. Finally, the Liaoning Power Grid is taken as an example for numerical analysis. The total amount of abandoned wind power on a certain day is 42.86 MW·h. The numerical analysis results show that the proposed cluster optimization strategy has absorbed 94.8% of the Liaoning grid's abandoned wind power. And compared with the traditional operation mode and the cost of the operation mode without considering abandoning wind consumption, the cost is reduced by 38.2% and 42.8%, respectively. In addition, the total energy consumption for producing fresh water is 99.35 MW·h, of which 40.9% comes from abandoned wind power. "Clean fresh water" has achieved remarkable results.
