对任何当前或未来电网进行建模的尝试都面临着巨大的挑战，因为电网是一个复杂的系统，具有反馈和多主体行为，由发电、配电、存储和消耗系统集成，使用各种控制和自动化计算系统来管理电流。我们的建模方法是建立在经过测试和验证的低压电网模型的基础上，将其扩展到广义能源模型。但是，为了解决能源效率的关键问题，需要额外的过程，如能源转换和存储以及进一步的能源载体，例如除了传统的电力之外，还必须考虑气体、热量等。因此，需要一个更强大的模型，配备增强的节点或转换点，能够处理多维流。本文解决了局部多载波能源网络建模的问题。该问题可以被视为对位于某些城市或农村地理区域的低压配电网进行建模的延伸。但是，在这项工作中，我们没有像电网中使用的那样使用外部潮流分析包来进行潮流计算，而是集成了多智能体算法来执行该任务，以与其他模拟任务并行的方式，不仅针对电流体，还针对许多附加能量载体。由于该模型主要关注系统运行，因此未开发发电和负荷模型。
Attempts to model any present or future power grid face a huge challenge because a power grid is a complex system, with feedback and multi-agent behaviors, integrated by generation, distribution, storage and consumption systems, using various control and automation computing systems to manage electricity flows.Our approach to modeling is to build upon an established model of the low voltage electricity network which is tested and proven, by extending it to a generalized energy model.But, in order to address the crucial issues of energy efficiency, additional processes like energy conversion and storage, and further energy carriers, such as gas, heat, etc., besides the traditional electrical one, must be considered. Therefore a more powerful model, provided with enhanced nodes or conversion points, able to deal with multidimensional flows, is being required.This article addresses the issue of modeling a local multi-carrier energy network. This problem can be considered as an extension of modeling a low voltage distribution network located at some urban or rural geographic area. But instead of using an external power flow analysis package to do the power flow calculations, as used in electric networks, in this work we integrate a multiagent algorithm to perform the task, in a concurrent way to the other simulation tasks, and not only for the electric fluid but also for a number of additional energy carriers. As the model is mainly focused in system operation, generation and load models are not developed.
