阿联酋超过90%的饮用水依赖海水淡化,该过程消耗约15%的电力,贡献了超过22%的能源相关二氧化碳排放。面对海水温度升高、盐度增加及气溶胶光学深度(AOD)等气候不确定性,太阳能淡化系统性能受光伏积尘、膜污染和水浊度循环严重影响。本研究提出一种新型两阶段预测架构:第一阶段利用卫星时序数据与气象信息预测AOD;第二阶段结合预测的AOD及其他气象因子,评估淡化效率损失。模型整体准确率达98%,并采用SHAP方法识别系统退化的关键驱动因素。基于预测结果,提出尘敏型规则控制逻辑,用于调节进水压力、优化维护计划、动态切换能源来源。研究成果集成于交互式仪表盘,支持情景模拟与预测分析,为气候适应型规划提供管理决策支持。
原文摘要 · Abstract (English)
The United Arab Emirates (UAE) relies heavily on seawater desalination to meet over 90% of its drinking water needs. Desalination processes are highly energy intensive and account for approximately 15% of the UAE's electricity consumption, contributing to over 22% of the country's energy-related CO2 emissions. Moreover, these processes face significant sustainability challenges in the face of climate uncertainties such as rising seawater temperatures, salinity, and aerosol optical depth (AOD). AOD greatly affects the operational and economic performance of solar-powered desalination systems through photovoltaic soiling, membrane fouling, and water turbidity cycles. This study proposes a novel pipelined two-stage predictive modelling architecture: the first stage forecasts AOD using satellite-derived time series and meteorological data; the second stage uses the predicted AOD and other meteorological factors to predict desalination performance efficiency losses. The framework achieved 98% accuracy, and SHAP (SHapley Additive exPlanations) was used to reveal key drivers of system degradation. Furthermore, this study proposes a dust-aware rule-based control logic for desalination systems based on predicted values of AOD and solar efficiency. This control logic is used to adjust the desalination plant feed water pressure, adapt maintenance scheduling, and regulate energy source switching. To enhance the practical utility of the research findings, the predictive models and rule-based controls were packaged into an interactive dashboard for scenario and predictive analytics. This provides a management decision-support system for climate-adaptive planning.
