美国丰富的天然气和对清洁电力的需求促使燃气发电厂的广泛安装，并使电力系统严重依赖可靠的天然气供应。使用天然气发电机进行峰值负荷和备用发电会导致高压天然气输送系统的取水量日内波动较大，从而导致天然气价格波动和供应中断，影响发电机调度并威胁电力和天然气系统的安全。在本手稿中，我们研究了不同的气体压缩机运行策略及其对受影响电力系统的影响。具体来说，我们考虑恒定的增压比和这些比率的动态调整以跟踪压力设定点。我们还使用动态气流模型对发电机调度计划和气体压缩机协议进行联合优化。我们开发了易于处理、物理上精确的实施方案，使用具有 24 和 25 个节点（通过燃气发电机耦合）的电力和燃气系统的测试网络集成模型进行比较。这证明了通过全球优化天然气系统运行和加强气电协调可以实现的好处。
The abundance of natural gas in the United States and the need for cleaner electric power have prompted widespread installation of gas-fired power plants and caused electric power systems to depend heavily on reliable gas supplies. The use of gas generators for peak load and reserve generation causes high intra-day variability in withdrawals from high pressure gas transmission systems, which leads to gas price fluctuations and supply disruptions that affect electric generator dispatch and threaten the security of both power and gas systems. In this manuscript, we investigate different gas compressor operation policies and their influence on the affected power system. Specifically, we consider constant pressure boost ratios and dynamic adjustment of these ratios to track pressure set-points. We also implement a joint optimization of generator dispatch schedules and gas compressor protocols using a dynamic gas flow model. We develop tractable, physically accurate implementations that are compared using an integrated model of test networks for power and gas systems with 24 and 25 nodes, which are coupled through gas-fired generators. This demonstrates the benefits that can be achieved with globally optimized gas system operations and increased gas-electric coordination.
