天然气和电力系统之间日益增长的相互依赖性，由燃气发电机和电力供应的气体压缩机驱动，需要详细调查这些向量之间的相互作用，特别是在可再生能源日益普及的背景下。在这项研究中，提出了一个扩展规划模型的综合天然气和电力系统。该模型研究了电池储能、需求侧响应和燃气发电机等灵活性选项的最优投资。这些灵活性选项的价值是量化的天然气和电力系统在英国在2030年。结果表明，灵活性选项可以发挥重要作用，在实现未来的排放目标。然而，这些选项的投资成本极大地影响了未来的发电组合以及天然气系统基础设施的加固类型。通过部署灵活性选项，与不考虑灵活性选项的情况相比，天然气和电力系统的规划和运营每年可节省高达242亿英镑的成本。
The growing interdependencies between natural gas and power systems, driven by gas-fired generators and gas compressors supplied by electricity, necessitates detailed investigation of the interactions between these vectors, particularly in the context of growing penetration of renewable energy sources. In this research, an expansion planning model for integrated natural gas and power systems is proposed. The model investigates optimal investment in flexibility options such as battery storage, demand-side response, and gas-fired generators. The value of these flexibility options is quantified for gas and electricity systems in Great Britain in 2030. The results indicate that the flexibility options could play an important role in meeting the emission targets in the future. However, the investment costs of these options highly impact the future generation mix as well as the type of reinforcements in the natural gas system infrastructure. Through the deployment of the flexibility options up to £ 24 .2 billion annual cost savings in planning and operation of natural gas and power systems could be achieved, compared to the case that no flexibility option is considered.
