Coordinating Flexible Ramping Products with Dynamics of the Natural Gas Network [PDF]

open access: yesarXiv, 2022
In electricity networks with high penetration levels of renewable resources, Flexible Ramping Products (FRPs) are among the utilized measures for dealing with the potential fluctuations in the net demand. This paper investigates the impacts of FRPs on the operation of interdependent electricity and natural gas networks.

Dynamic Security Region of Natural Gas Systems in Integrated Electricity-Gas Systems [PDF]

open access: yesarXiv, 2023
In an integrated electricity-gas system (IEGS), the tight coupling of power and natural gas systems is embodied by frequent changes in gas withdrawal from gas-fired units to provide regulation services for the power system to handle uncertainty, which may in turn endanger the secure operation of the natural gas system and ultimately affect the safety ...
