能量供应系统通常被认为是具有独立能量矢量的独立子系统。然而，热电联产（CHP）机组，热泵和电锅炉的使用在电力和热力网络之间建立了联系。提出了两种将电力和热力网络作为一个整体来研究的联合分析方法。这两种方法分别是以潮流和简单优化调度的形式进行分解和集成的电-水-热计算技术。这两种方法都是基于电网，液压和热回路，以及耦合组件的模型，重点是热电联产机组和循环泵。对巴里岛电力和区域供热网络进行了案例研究，显示了如何使用热电联产装置满足自给自足系统（不与外部系统互连）的电力和供热需求。结果表明，集成方法比分解方法需要更少的迭代次数。(C)2015年，作者。由爱思唯尔有限公司出版。这是一篇开放获取的文章，使用CC BY许可证（http：//creativecommons.org/licenses/by/4.0/）。
Energy supply systems are usually considered as individual sub-systems with separate energy vectors. However, the use of Combined Heat and Power (CHP) units, heat pumps and electric boilers creates linkages between electricity and heat networks. Two combined analysis methods were developed to investigate the performance of electricity and heat networks as an integrated whole. These two methods were the decomposed and integrated electrical-hydraulic-thermal calculation techniques in the forms of power flow and simple optimal dispatch. Both methods were based on models of the electrical network, hydraulic and thermal circuits, and the coupling components, focusing on CHP units and circulation pumps. A case study of Barry Island electricity and district heating networks was conducted, showing how both electrical and heat demand in a self-sufficient system (no interconnection with external systems) were met using CHP units. The comparison showed that the integrated method requires less iteration than the decomposed method. (C) 2015 The Authors. Published by Elsevier Ltd.
