Non-Conventional Power Generation System Simulation by using Multilevel Inverters

Download Paper


This paper presents comparison between modified five level and nine level inverters for an efficient renewable power generation system. A multi-level inverter is developed and applied for injecting the real power of the renewable power into the grid to reduce the switching power loss, harmonic distortion, and electromagnetic interference caused by the switching operation of power electronic devices. Here a dual buck configuration with full bridge inverter is used for the MLI implementation. The input of the dual-buck converter is dc capacitor voltage sources. The output voltage of the dual-buck converter supplies to the full-bridge inverter. The power electronic switches of the full-bridge inverter are switched in low frequency synchronous with the utility voltage to convert the output voltage of the dual-buck converter to a multi-level ac voltage. The output current of the multi-level inverter is controlled to generate a sinusoidal current in phase with the utility voltage to inject into the grid. Five level and nine level topologies are developed to verify the performance of the developed renewable power generation system. The results of MATLAB modeling of the system detail the comparative operation of inverter topologies which are conventional five level inverter and nine level inverter topology to reduce total harmonic distortions in grid voltage and electromagnetic interference. The proposed control scheme to mitigate the power quality issues for power quality improvement in grid integrated DER simulated using MATLAB/ SIMULINK in power system block set.
