电力和天然气系统正在向低碳和更综合的能源系统快速过渡。其中一个途径是住宅供暖电气化，其影响可以通过对这两个系统进行联合建模来更好地量化。本文提出了一种新的综合电力和天然气输送系统模型，具有高时空分辨率和现实的系统运行约束。电力系统模型是一个单元组合与加强直流最优潮流，制定为一个混合整数线性规划。天然气网络模型由动态气体流量模型组成，动态气体流量模型捕获天然气网络的灵活性，如通过管线包测量的。该模型是实现预计2025年的案例研究与实际的维多利亚州的传输系统，假设使用空气-水电热泵的空间供暖和生活热水。在考虑的具体假设和情景的背景下，结果表明：（一）住宅电气化通常需要额外的进口和/或本地发电，在全面电气化的情景中，互连和州内输电线路也可能需要增加;（二）天然气网络可以提供系统在大多数电气化情况下所需的灵活性;以及（iii）随着电气化的增加，电力-天然气二氧化碳排放总量可能会略有增加。
Electricity and gas systems are undergoing a fast transition towards low-carbon and more integrated energy systems. One of those pathways is the electrification of residential heating, whose impacts can be better quantified by jointly modeling the two systems. This paper presents a novel integrated electricity and gas transmission system model with high spatiotemporal resolution and realistic system operating constraints. The electricity system model is a unit commitment with a strengthened DC optimal power flow, formulated as a mixed-integer linear program. The gas network model consists of a dynamic gas flow model that captures gas network flexibility, as measured by the linepack. The model is implemented on projected 2025 case studies with the actual Victorian transmission systems, assuming the use of air-to-water electric heat pumps for both space heating and domestic hot water. In the context of the specific assumptions and scenarios considered, results suggest that: (i) residential electrification will generally require additional imports and/or local generation, and interconnectors and intra-state transmission lines may also need augmentation in scenarios with full electrification; (ii) the gas network can provide the flexibility needed by the system in most electrification cases; and (iii) the total electricity-gas CO2 emissions might slightly increase as electrification increases.
