To deal with the challenge of the level of penetration of renewable energy sources against uncertainties and in order to develop the secondary load frequency control loop, with the aim of reducing the impact of disturbances and adjusting the resistant gain coefficient to uncertainties, using a virtual inertial controller based on the resistant control of the Mu-synthesis method. For the lack of inertia in the islanded microgrid clusters, alternating current has been done. The stability and performance of this method is proved based on the structured singular value. The experimental results of the hardware in the loop by the TMS320F2812 digital signal processor and the simulation in the MATLAB/SIMULINK software environment confirm the performance of the proposed controller for the development of traditional load frequency control in comparison with the enhanced virtual inertial control and inertialess mode, under various disturbances, that the application of the controller The virtual inertia based on Mu-synthesis improves the stability of islanded microgrid clusters and damping of power fluctuations, and also reduces frequency deviations to a significant extent. |
