| 摘要: |
| 现有关于综合能源系统潮流的研究大多以电力、热力、燃气系统耦合形成的多能系统为研究主体，而少量关于电-水联合系统潮流的研究又存在耦合方式单一、模型适应性差等问题。为此面向区域供电、供水综合服务商，提出配电网、配水网耦合形成的区域电-水联合系统的潮流模型和计算方法。提出2种用户级电-水能源集线器模型以描述终端用户综合用能行为产生的电-水关联关系；在此基础上，考虑电-水之间的泵站耦合和用户级能源集线器2种耦合方式，以及水负荷的水压特性，提出区域电-水联合潮流模型及计算方法；用2个不同规模的区域电-水联合系统验证了所提潮流计算方法的有效性，并对比分析了用户级电-水能源集线器及水负荷水压特性对联合潮流的影响。 |

| Abstract: |
| Most existing researches on the load flow analysis of integrated energy system focus on the multi-energy system composed of power, heat and natural gas system. There are only a few researches on the load flow of IEWS(Integrated Electricity-Water System),which, however, suffer from the problems of single coupling mode and poor adaptability. To address these problems, the load flow model and its calculation method for a regional IEWS composed of a power distribution network and a water distribution network are proposed to provide an analysis tool for the regional integrated electricity-water service providers. Firstly, two user-level electricity-water energy hub models are established to describe the electricity-water relationship of integrated energy consumption behaviors of terminal users. On this basis, the approach to calculate the regional integrated electricity-water load flow is proposed. In this model, different couplings between electricity and water(i. e. the couplings through pump station and user-level energy hubs),and the pressure-demand relationship of water loads are taken into account. The proposed method is verified by two regional IEWS test cases that have different scales. The impacts of user-level electricity-water energy hubs and the pressure-demand characteristics of water loads on the load flow distribution are compared and discussed. |
