Abstract

Gas turbines play core roles in clean energy supply and the construction of comprehensive energy systems. The control performance of primary frequency modulation of gas turbines has a great impact on the frequency control of the power grid. However, there are some control difficulties in the primary frequency modulation control of gas turbines, such as the coupling effect of the fuel control loop and speed control loop, slow tracking speed, and so on. To relieve the abovementioned difficulties, a control strategy based on the desired dynamic equation proportional integral (DDE-PI) is proposed in this paper. Based on the parameter stability region, a parameter tuning procedure is summarized. Simulation is carried out to address the ease of use and simplicity of the proposed tuning method. Finally, DDE-PI is applied to the primary frequency modulation system of an MS6001B heavy-duty gas turbine. The simulation results indicate that the gas turbine with the proposed strategy can obtain the best control performance with a strong ability to deal with system uncertainties. The proposed method shows good engineering application potential.
