Microgrids Power Quality Enhancement Using Model Predictive Control

In electric power systems, any deviation with respect to the theoretical sinusoidal waveform is considered be a disturbance in quality of electrical grid. The can alter parameters waveform: frequency, amplitude, and symmetry among phases. Microgrid, as part system, has contribute providing an adequate current grid connected-mode, well guarantee similar voltage features than standard requirement given for public distribution grids under normal exploitation conditions islanded mode. Adequate supply necessary correct compatibility between all devices connected same this paper, microgrids managed using Model Predictive Control (MPC) methodology which regulates converters order achieve requirements. control algorithm developed following working modes: grid-connected, islanded, interconnected. simulation results demonstrate that proposed improves transient response comparison classical methods modes, minimizing harmonic content even presence non-balanced non-harmonic-free three-phase systems.
