摘要

尽管特征法（MOC）是一种精确的气体流动动力学离散方法，但在步长不合适的情况下容易出现不稳定性。这封信以 lEGS 的优化调度为背景，探讨了 MOC 在数值稳定性方面的局限性。具体来说，所提出的方法可以在不牺牲精度的情况下实现灵活的时间步长，从而显著减少因数值振荡而导致的不收敛现象。通过在不同模拟环境中进行案例研究，验证了所提方法的有效性。

Optimal Scheduling of Integrated Electricity and Gas System with Numerical Stability Condition-Free Method

Though an accurate discretization approach for gas flow dynamics, the method of characteristics (MOC) is liable to instability for inappropriate step sizes. This letter addresses the numerical stability limitation of MOC, in the context of lEGS's optimal scheduling. Specifically, the proposed method enables flexible temporal step sizes without sacrificing accuracy, significantly reducing non-convergence due to numerical oscillations. The effectiveness of the proposed method is validated through case studies in different simulation settings.
