随着低碳供热技术的引入，热力、电力和天然气行业之间的相互作用日益增加，需要建立模型来评估网络层面的行业间相互作用。本文提出了一种新的集成电，热，气传输网络模型，考虑电力和天然气网络流量耦合的供热部门的燃料需求。后者是在节点网络级别和半小时的基础上建模的，建立在第一部分中提出的高分辨率时间和空间热需求模型的基础上。特别是，这里的建模进一步发展，包括一个集成的热-电-气优化，以评估不同的加热技术，特别是混合技术的操作。更具体地说，直流潮流建模与稳态天然气网络能量和运输成本优化相结合，以评估天然气-电力价格的相互作用，并与瞬态天然气流量建模天然气网络运营研究。对英国能源系统进行了数值案例研究，考虑了向低碳未来的发展、混合双燃料电动热泵/燃气锅炉技术的运行以及缓解燃气网络限制的能力。弹性案例研究考虑节点天然气价格的影响下天然气网络供应冲击也被认为是。研究结果显示，电力部门的供热和脱碳途径可以使供热和电力部门的碳排放减少75%，使用混合供热技术可以将传统发电峰值减少24%。此外，它表明，利用天然气需求响应可以提供一个额外的弹性选项的天然气网络。(C)2018由Elsevier Ltd.出版
With the increasing interactions between the heat, electricity and gas sectors due to the introduction of low carbon heating technologies, there is a need for models to assess the inter-sector interactions at a network level. This paper presents a novel integrated electricity-heat-gas transmission network model that considers electrical and gas network flows coupled with the fuel requirements for the heating sector. The latter is modelled at a nodal network level and on a half-hourly basis, building upon the high resolution temporal and spatial heat demand model presented in Part I. In particular, here the modelling is developed further to include an integrated heat-electricity-gas optimization to assess the operation of different heating technologies, and particularly hybrid ones. More specifically, DC power flow modelling is coupled with steady-state gas network energy and transportation cost optimization to assess gas-electricity price interactions, and with transient gas flow modelling for gas network operational studies. Numerical case studies are performed on the GB energy system, considering the evolution towards a low carbon future, the operation of hybrid dual-fuel electric heat pump/gas boiler technologies, and the ability to alleviate gas network constraints. Resilience case studies considering nodal gas price implications under gas network supply shocks are also considered. The results show how pathways to electrify heating and decarbonise the power sector can lead to a 75% reduction in carbon emissions of the heat and electricity sectors and that using hybrid heating technologies can reduce conventional generation peaks by 24%. Additionally, it is shown that exploiting gas demand response can provide an additional resilience option to the gas network. (C) 2018 Published by Elsevier Ltd.
