Microgrid Stability and Damping Improvement Using Virtual Synchronous Generator

This paper develops Microgrid control scheme includes virtual synchronous generators using an optimal linear quadratic regulator-based technique to improve frequency stability and oscillation damping. The designed structure of the virtual synchronous generators provides an ability to emulate the dynamic behavior of conventional synchronous generators. The linear quadratic regulator controller optimally tunes the damping coefficient. The comparing simulation results are obtained using MATLAB/Simulink to illustrate the efficiency of the proposed approach in ensuring stability and improving damping under wide operating conditions.
