Abstract

This paper proposes an enhanced control strategy for islanded AC microgrids, targeting the challenges of power-sharing, and voltage magnitude and frequency control. The proposed approach combines the Interconnection and Damping Assignment Passivity-Based Control (IDA-PBC) method with droop control to control active and reactive power-sharing, as well as voltage magnitude and frequency. A port-controlled Hamiltonian model is developed to synthesize the control laws ensuring local stability at the microgrid’s equilibrium point. In comparison to previous IDA-PBC approaches presented in the literature, the approach proposed in this paper integrates droop control to improve dynamic performance and enable effective load sharing among distributed generation units. The performance of the proposed approach is evaluated using MATLAB/Simulink simulations on an islanded microgrid consisting of two sources and a constant impedance load. The obtained results demonstrate accurate active and reactive power-sharing, as well as efficient voltage control under disturbances.
