Model Predictive Control for Multilevel Inverters in Microgrids
Power electronics converters play an important role in realization and performance improvement of electrical power system. With the demand for new power resource and better power supply quality, more and more distributed energy resources (DERs) come into practice. As a new network configuration, microgrid attracts much attention, consequently lots of new power electronics devices and engineering experiments are brought forward. The paper focus on the multilevel inverters in microgrid, discusses its topologies and characteristics. A model predictive controller is designed to decrease common mode voltages and errors between the capacitor voltages and their reference values. Finally, simulation diagram, parameters and results using software PLECS are provided to demonstrate the merits of multilevel inverters and the validity of proposed control method.
