Dynamic Energy Flow Analysis of Integrated Electricity and Gas Systems: A Semi-Analytical Approach
Zhikai Huang, Shuai Lu, Wei Gu +4
Ensuring the safe and reliable operation of integrated electricity and gas systems (IEGS) requires dynamic energy flow (DEF) simulation tools that achieve high accuracy and computa…
Quantify Gas-to-Power Fault Propagation Speed:A Semi-Implicit Simulation Approach
Ruizhi Yu, Suhan Zhang, Wei Gu +1
Relying heavily on the secure supply of natural gas, the modern clean electric power systems are prone to the gas disturbances induced by the inherent rupture and leakage faults. F…
Nonlinear PDE Constrained Optimal Dispatch of Gas and Power: A Global Linearization Approach
Yuan Li, Shuai Lu, Wei Gu +4
The coordinated dispatch of power and gas in the electricity-gas integrated energy system (EG-IES) is fundamental for ensuring operational security. However, the gas dynamics in th…
Semi-implicit Continuous Newton Method for Power Flow Analysis
Ruizhi Yu, Wei Gu, Yijun Xu +2
As an effective emulator of ill-conditioned power flow, continuous Newton methods (CNMs) have been extensively investigated using explicit and implicit numerical integration algori…
Non-iterative Calculation of Quasi-Dynamic Energy Flow in the Heat and Electricity Integrated Energy Systems
Ruizhi Yu, Wei Gu
Quasi-dynamic energy flow calculation is an indispensable tool for the heat and electricity integrated energy system (HE-IES) analysis. One solves the nonlinear partial differentia…
