The intrinsic flexibility of integrated electricity and gas systems (IEGSs) hinges on the gas
flow dynamics dictated by partial differential equations (PDEs). However, conventional …

Power systems are shifted from conventional bulk generation toward renewable generation.
This trend leads to the frequency security problem due to the decline of system inertia. On …

The interdependency among the electricity, gas, heat, and cooling energy systems is ever-
increasing. The flexible energy utilization patterns on the demand side and gas flow …

This paper addresses the problem of coordinating the operation of electricity and natural gas
(NG) transmission systems with green hydrogen (H 2) production and injection into existing …

Due to their slow gas flow dynamics, natural gas pipelines function as short-term storage,
the so-called linepack. By efficiently utilizing linepack, the natural gas system can provide …

Green hydrogen from renewable sources can be blended with natural gas and serves as a
potentially feasible measure for contributing to the net zero energy sector. The time-varying …

Power-to-gas facilities consume surplus renewable electricity generation to produce
alternative gases, such as green hydrogen. They can be injected into, and transported by …

As the integrated gas-electricity system (IEGS) grows within the context of carbon
abatement, natural gas shippers (NGSs) face a twofold challenge: perceiving the dynamic …

This paper proposes a novel spatial branch-and-cut approach for fast resilience analysis of
integrated electricity-gas systems. The proposed method makes two improvements to the …

In the early commercialization stage of hydrogen fuel cell vehicles (HFCVs), reasonable
hydrogen supply infrastructure (HSI) planning is a premise for promoting the popularization …
