A New Coordination Scheme of a Frequency Control for Multi-Area Microgrids Considering Modified Virtual Rotor

Abstract:

In microgrid (MG) power systems, frequency regulation can be supported by adding a virtual rotor. This research investigates an adaptive control strategy using a modified virtual rotor-based derivative technique (virtual rotor+ virtual damping) and supported by Jaya optimizer based on balloon effect modulation (BE) to provide the optimal value of the integral controller on the secondary frequency controller in islanded and interconnected MGs. The proposed modified rotor is added as an auxiliary controller to emulate the reduction in system inertia and the enhanced damping properties. The performance of the suggested adaptive control strategy is validated through simulation in the MATLAB/Simulink environment. A comparative study between the conventional integral controller, classic Jaya with/without virtual inertia, in presence of BE is presented. The final findings emphasize the superiority of the proposed frequency control strategy (Jaya-based BE+ modified virtual rotor) and show the better performance and stability of the MGs compared to other controllers.
