考虑界面太阳能蒸汽发电的海岛微电网水-电-氢协同优化OA

To address the challenges of freshwater scarcity and renewable energy volatility on islands,an island mi⁃crogrid system incorporating interfacial solar steam generation(ISSG)and wave energy generation was proposed in this paper,which utilizes a polyvinylidene fluoride biomass carbon-based photothermal membrane to simultaneously enable photothermal power generation and seawater desalination.First,an optimization model of island microgrid considering ISSG was developed,focusing on the coordinated configuration of water-electricity-hydrogen to meet the electrical load,hydrogen demand and freshwater requirements.Second,to handle the renewable energy uncertainties,Latin hypercube sampling combined with the Kantorovich scenario reduction technique was employed to obtain the prediction values.Third,an optimal dispatching model was constructed,incorporating the constraints such as operation costs,energy cou⁃pling and equipment operation.Finally,verification was conducted with one island in Zhejiang Province taken as an ex⁃ample.Results demonstrate that the proposed model can effectively satisfy regional hydrogen and freshwater demands while achieving substantial freshwater production and considerable economic benefits from hydrogen production by elec⁃tricity,which verify the system's comprehensive advantages in enhancing renewable energy utilization and improving the energy self-sufficiency for island communities.
