The dynamic mathematical model of a micro gas turbine was analyzed. By the use of an analytical method solved was the dynamic equation of a single-shaft gas turbine with a recuperator. A simulation has been conducted of the gas turbine load variation and shedding for the following two cases, namely, operation under a constant speed and under a variable speed. Moreover, a viable approach is proposed for the dynamic performance optimization under turbine off-design operating conditions and for an optimized turbine control process. The work described above can provide a theoretical guide for organizing the operation of practical turbine units and the rational matching of system performance parameters.
