Evaluation of Gas Turbines Efficiency in the Frequency Control Mode Using Experimental Data

This paper provides experimental results about the efficiency of gas turbines operated in part-load mode. Load frequency control plays a vital role in electric power production as it offers the most important generation control of power plants. In order to participate in frequency control, power stations must change from pre-select mode to the part-load condition. Evaluating the efficiency of the units operated in socalled modes, leads to more precise pricing for articipation in frequency control ancillary service market. In this paper, it is considered gas turbines operated in both modes and results are provided. Comparison of experimental results obtained from a real case study shows that the efficiency of the gas turbines has very low decrease in the part-load mode.
