摘要: 随着可再生能源的持续开发利用和高效能源转换技术的不断涌现,电、天然气、热等能源系统之间的相互依赖性不断增强,使得供能系统呈现多能耦合发展趋势。水是能源生产和转化过程中最必需的物质之一,而供水系统中水泵的运行依赖于电能驱动,使得供能系统和供水系统存在双向耦合关系。以工业园区为对象,综合考虑其水资源及多种能源需求,针对工业园区供水-供能耦合系统规划开展研究,采用典型场景建立了基于多场景的水-能耦合协同规划模型。同时,考虑园区中分布式光伏发电出力的不确定性,提出了供水-供能耦合系统的鲁棒规划方法,保障了供能、供水的可靠性。采用列和约束生成算法求解建立的鲁棒规划模型,仿真结果验证了所提出模型和方法的有效性和合理性。该联合规划可有效提升供水-供能联合系统的灵活性,并降低能源和资源系统的规划投资及运行成本。

Abstract: With the continuous development and utilization of renewable energy and the continuous emergence of efficient energy conversion technologies, the interdependence among power, natural gas, heating and other energy systems is increasly strengthened, and the energy supply system develops in a multi-energy coupling way. Water is one of the most necessary substances in the process of energy production and conversion, while the operation of water pump in the water supply system depends on electric energy drive, thus forming a two-way coupling relationship between the energy supply system and water supply system. By taking an industrial park as the object, and taking its water resources and various energy needs into comprehensive consideration, this paper studies the water-energy coupling system planning of industrial parks, and establishes a water-energy nexus cooperative planning model based on multiple scenarios. At the same time, considering the output uncertainty of the distributed solar power generation in the park, a robust programming method is proposed for the water-energy nexus system to ensure the reliability of energy supply and water supply. The column and constraint generation algorithm is used to solve the robust programming model. The simulation results have verified the validity and rationality of the proposed model. The proposed co-planning can effectively improve the flexibility of the water-energy coupling system, and reduce the cost for investment planning and operation of energy and sources system.
