Modeling and Simulation of PV based single phase seven level grid connected inverter system

Electrical Engineering

In the field of high-power medium-voltage energy regulation, multilevel inverters are a viable option. This project features cascaded multi-cells with independent DC sources. Multilevel inverters are promising since their output voltage waveform is virtually sinusoidal. For grid-connected solar systems, the standard is a single seven-level inverter with a new pulse width-modulated (PWM) control technique. Two H-bridge inverters with distinct dc sources were employed in this project. The proposed system's major goal is to reduce fluctuation, or if there are any louds, it requires a pure sinusoidal waveform. The industry creates and consumes that much space. Any device will work properly if it is utilised in a micro grid like this. In this proposal, a buck boost converter is used to manage photovoltaic power. The proposed system employs the MPPT technology to completely use the maximum amount of energy available from solar panels to the grid. Simulations in MATLAB/SIMULINK were used to verify the proposed system's performance.
