Enhancing power stability and efficiency with multilevel inverter technology based on renewable energy sources

Abstract

Power conversion raises harmonics, which can cause increased losses and decreased power stability. The limitations of conventional inverters can be addressed by using the technological innovations of multilevel inverters. In recent years, there has been a growing use of multilevel inverter technologies as affordable alternatives for many industrial applications. In addition to having fewer components and switching losses, this architecture provides superior output voltage/current waveforms. The most crucial need for multilevel inverters is the minimization of total harmonic distortion that can be present at the output side of the DC/AC inverter for both voltage and current waveforms. This study proposes a system that consists of five distinct renewable energy sources with output voltages of 1E, 2E, 3E, 4E, and 21E. A new control technology is utilized to achieve 63 voltage levels at the output. Renewable energy sources include battery systems, wind turbines, PV systems, diesel generators, and hydropower plants. Different scenarios are proposed in this work to ensure proper system design and maintenance of the power supply, such as the loss of one or two of the renewable energy sources mentioned above.
