In the micro gas turbine power generation system,the speed stability is very important for the efficiency and operation safety of the micro gas turbine,while the load change has a great impact on the speed stability of the gas turbine.For this reason,a flexible coordinated control strategy for micro gas turbine power generation system was proposed.The strategy controlled the speed fluctuation caused by the load change by the gas turbine and the converter to form the"mechanical-electric"coordinated control.The results show that the accuracy of the control strategy is guaranteed while accelerating the power dynamic response,and the speed instability of the micro gas turbine system due to reaching the temperature limit is avoided.
