Abstract
In the modern era of renewable energy generation and distribution, injecting solar power into the utility grid has gained universal recognition, also solar energy plays a crucial role for smart cities development. Grid-connected asymmetrical multilevel inverters have undergone significant development for integrating solar into the utility grid. This article aims to implement a 15-level asymmetrical inverter in a single-phase grid-integrated PV system and analyses the proposed system working with a 15-level inverter. This inverter topology has fewer switching devices, design with three DC sources and can generate fifteen output voltage levels; in this proposed system, these three DC sources are designed by three PV modules and three conventional boost converters. P&O (Perturb and Observe) Algorithm was implemented on each boost converter to extract the maximum power from three PV modules. The proposed system is simulated in MATLAB 2023a with toolboxes. The simulation results show whether the inverter can export the power to the grid under various solar irradiance conditions. The solar-based proposed system is well suited for groups of houses in smart cities.
