Abstract: The growing emphasis on environmental sustainability underscores the need for cleaner and more efficient energy sources. Combined cycle gas turbines (CCGTs) play a pivotal role in this transition due to their high efficiency, operational flexibility, and lower emissions. As CCGT penetration increases, accurately modeling their performance becomes critical for reliable power system operation. Ambient temperature is one of the key parameters that significantly influences CCGT performance. This paper investigates the impact of temperature-dependent CCGT performance on the unit commitment (UC) problem, emphasizing the influence of ambient temperature across different operating states.
