Description
Summary:[...]the increasing popularity of natural gas usage, especially by GT units, will lead to more frequent occurrence of natural gas scarcity and inadequacy. [...]the energy integration will eventually be hindered when the secure and reliable operation of the integrated electric power and natural gas system cannot be guaranteed. Impacts of Natural Gas System and Equivalent Reserve Capacity Estimation Since GT units consume natural gas as the main energy fuel, an increase in GT capacity will strengthen the coupling between the power and natural gas system [13]. [...]observing and analyzing the corresponding influence on the power system’s operational state is not only helpful for reasonable resource allocation, but also essential to prevent cascading failures. 3.1. GT units are on flexible contracts and are entitled to get natural gas supply when there is any surplus. [...]the combined uncertainty of the natural gas production rate and the residential natural gas consumption patterns will increase the fuel risks for GT units. In the worst case scenario, when the natural gas production rate is extremely low and the overall residential natural gas load is high, the consumption margin available for the GT units may not even be sufficient for the reserve requirement. [...]the production and consumption rates of natural gas should be examined for a power system that depends on GT units for reserve provision, and other reserve sources should be equipped if necessary.
