Abstract This paper presents an evaluation framework for Techno-Economic-Environmental (TEE) performance of the Integrated Gas and Electricity Distribution Networks (IGEDNs). The proposed framework is based on a coupled gas and electric load flow model, facilitating the consideration of all the parameters affecting the operation of IGEDNs, such as different gas mixtures, gas temperature, pipeline characteristics and the electricity network topology. This framework can assess the impact of different storage configurations, different levels of Renewable Energy Sources (RESs) and different levels of energy demand on the amount of imported energy from the upstream networks, operational costs and emissions of the IGEDNs. The evaluation framework can perform the TEE operational analysis of future scenarios of IGEDNs through various coupling components and storage devices including Single-Vector Storage (SVS) as well as Vector-Coupling Storage (VCS) devices to provide a basis for well-informed design choices for meeting the Greenhouse Gas (GHG) reduction targets. The TEE evaluation framework is tested on a real-world case study from a rural area in Scotland, and analysed from different aspects, to show the effectiveness of the model for analysis of the interactions of gas and electricity distribution networks. The results reveal that integrated operation of the gas and electricity networks improves all the considered technical, economic and environmental parameters.

考虑不同存储配置影响的综合燃气和电力分配网络的技术经济环境评估框架

摘要 本文提出了综合燃气和电力分配网络 (IGEDN) 的技术经济环境 (TEE) 性能评估框架。所提出的框架基于耦合的气体和电力负荷流模型，便于考虑影响 IGEDN 运行的所有参数，例如不同的气体混合物、气体温度、管道特性和电力网络拓扑。该框架可以评估不同存储配置、不同级别的可再生能源 (RES) 和不同级别的能源需求对从上游网络进口的能源数量、运营成本和 IGEDN 排放的影响。评估框架可以通过包括单向量存储 (SVS) 和向量耦合存储 (VCS) 设备在内的各种耦合组件和存储设备对 IGEDN 的未来场景进行 TEE 操作分析，为明智的设计选择提供基础实现温室气体 (GHG) 减排目标。TEE 评估框架在苏格兰农村地区的真实案例研究中进行了测试，并从不同方面进行了分析，以展示该模型在分析燃气和配电网络相互作用方面的有效性。结果表明，燃气和电力网络的集成运行改善了所有考虑的技术、经济和环境参数。
