能源-水关系的研究主要是通过讨论在数据调查和技术考虑的支持下的政策选择。在技术层面上，已经尝试优化电力和水系统之间的耦合点，以减少前者技术的水强度和后者技术的能源强度。据我们所知，很少有人从工程系统的角度讨论能源与水的关系。先前的一项工作提出了使用系统建模语言（SysML）开发的电力供应、工程供水和废水管理系统中能源-水关系的参考架构。在这项工作中，键合图用于开发模型，这些模型表征了参考架构中确定的电力、水和废水系统内部和之间物质和能量的显著传输。这些模型结合起来，就有可能在投入产出模型中将一个区域的能源和城市用水消耗与所需的取水量联系起来。
Theenergy–water nexushas been studied predominantly through discussions of policy options supported by data surveys and technology considerations. At a technology level, there have been attempts to optimize coupling points between the electricity and water systems to reduce the water-intensity of technologies in the former and the energy-intensity of technologies in the latter. To our knowledge, there has been little discussion of the energy–water nexus from an engineering systems perspective. A previous work presented a reference architecture of the energy–water nexus in the electricity supply, engineered water supply and wastewater management systems developed using the Systems Modeling Language (SysML). In this work, bond graphs are used to develop models that characterize the salient transmissions of matter and energy in and between the electricity, water and wastewater systems as identified in the reference architecture. These models, when combined, make it possible to relate a region’s energy and municipal water consumption to the required water withdrawals in an input–output model.
