本文提出了一种基于.不同能源基础设施，如电力、燃气和区域供热系统耦合潮流的联合优化方法。提出了一种稳态潮流模型，该模型包括任意数量的能量载体的转换和传输。根据能源枢纽的新概念，明确考虑了不同基础设施之间的耦合。利用该模型，提出了能量传输和转换的联合经济调度和最优潮流问题。给出了多个能源载体优化调度的一般最优性条件，并与电力系统的标准方法进行了比较。最后，通过实例对所开发的工具进行了演示。
This paper presents an. approach for combined optimization of coupled power flows of different energy infrastructures such as electricity, gas, and district heating systems. A steady state power flow model is presented that includes conversion and transmission of an arbitrary number of energy carriers. The couplings between the different infrastructures are explicitly taken into account based on the new concept of energy hubs. With this model, combined economic dispatch and optimal power flow problems are stated covering transmission and conversion of energy. A general optimality condition for optimal dispatch of multiple energy carriers is derived, and the approach is compared with the standard method used for electrical power systems. Finally, the developed tools are demonstrated in examples.
