面向海洋能综合利用的港口多能互补与生产调度协同优化

As the national strategic energy, rational exploitation and comprehensive utilization of ocean energy can promote the optimization of energy structure of ports. Meanwhile, the shortage of energy supplies in coastal areas can be alleviated. However, the coupling mechanism between energy structure in port production system and ocean energy power supplies is still not clear. Therefore, there is absolutely a need to clarify the internal relationship between the multi-scale spatiotemporal fluctuation of ocean energy power supplies and the dynamic change of port operation production scheduling. Besides, the ocean energy development is affected by the uncertain environment greatly. Considering the poor stability, intermittence and randomness of the ocean energy supply, it is necessary to study the collaborative optimization method of port energy allocation and production scheduling under uncertainties...Therefore, based on the mass data of energy development and port production, the topological structure and the demand of the energy structure of port production system are analyzed and forecast respectively. Then, the coupling relationship between energy structure in port production system and ocean energy power supplies is dissected deeply. Thirdly, the uncertainties of the external environment of ocean energy supplies and the energy demands of port production system are described. After that, a double-deck collaborative optimization model of hybrid-power-system port energy allocation and production operation scheduling is established to explore the strategy of port energy allocation and production scheduling. Finally, facing the comprehensive utilization of ocean energy, the collaborative optimization theories and methods of port hybrid power system and production operation scheduling are proposed. The research achievements aim to develop and utilize ocean energy reasonably, reduce port pollution, and provide a theoretical basis for green port operation and energy allocation and regulation decision in power sector.

海洋能作为国家战略开发能源，其合理开发和综合利用是优化港口用能结构、缓解沿海地区能源供应短缺的有效途径。但由于港口生产的用能结构与海洋能供给耦合关系机理尚不清晰，亟需厘清海洋能供给多尺度时空波动及生产调度动态变化的内在关系，针对海洋能开发受环境影响大、稳定性较差、间歇性和随机性等不确定环境特点，研究不确定性环境下港口多能互补与生产调度的协同优化方法。.为此，本研究基于海洋能开发与港口生产的海量数据，精准刻画港口作业系统能源结构；深入剖析港口作业系统用能结构与海洋能供给耦合关系机理；解析海洋能供给外部环境和港口生产作业系统能源需求的不确定性；构建多能互补的港口能源调配与生产调度双层协同优化模型；探索港口能源调配与生产调度策略；揭示面向海洋能综合利用的港口多能互补与生产调度协同优化理论与方法。研究成果为合理开发利用海洋能、减少港口污染，绿色港口建设及电力部门的能源调配与调控决策提供理论依据。

海洋能作为国家战略开发能源，其合理开发和综合利用是优化港口用能结构、缓解沿海地区能源供应短缺的有效途径。海洋能具有受环境影响大、稳定性较差、间歇性和随机性等不确定性强的特点，因而利用海洋能优化港口用能结构与传统能源供应存在较大差异。目前海洋能在港口上应用的研究尚不成熟，港口生产的用能结构与海洋能供给耦合关系机理尚不清晰，亟需厘清海洋能供给多尺度时空波动及生产调度动态变化的内在关系，针对研究不确定性环境下港口多能互补与生产调度的协同优化方法。.本项目考虑港口生产作业系统不确定性强的特点，提出港口生产作业系统中各设备与装卸机械在作业过程中能源消耗拓扑结构表达，构建港口生产作业系统精细化仿真模型，确定港口生产作业系统实时能源需求。采用概率分析、数学建模以及仿真实验等方法，提取海洋能供给特征，得到了不确定条件下的海洋能供给时变规律，探究了海洋能供给与港口生产作业系统用能结构的耦合关系。分析了港口生产调度过程中的不确定性因素对港口多能互补能源结构下的生产能源需求的影响，建立了港口多能互补能源结构优化模型，获得不确定条件下多能互补的港口能源调配方案。在构建港口资源动态调度优化模型，优化调度港口生产作业系统资源的基础上，建立了不确定条件下集装箱港口多能互补与生产作业系统调度协同优化模型，分析了不同生产作业系统调度优化方案对集装箱码头生产系统多能互补能源结构的影响。
