Performance Analysis of Two Stage Three-Phase Grid Connected Inverter for Photovoltaic Applications

The Grid linked Photovoltaic (PV) systems operate similarly with existing sources to supply power to the power grid. This study discusses about the development and MATLAB simulations of a two stage three-phase grid linked to a solar photovoltaic system without the need for a controller. The MATLAB simulation platform could be a part of the pv grid-connected devices. This work is the initial to demonstrate the control system by the two-stage process, sun’s light (solar) with three phases and grid connection. It makes it possible for an inverter designed for grid-connected photovoltaic panels to sync the result of a load current with a grid of voltages. The maximum power point tracking (MPPT) control mechanism, inverter and converters synchronization, and power grid are indeed the main topics discussed herein. MPP calculation, which enables the converter and inverter to operate efficiently, is made possible by tracking the dc voltage and current. Then examine the converter’s both input and output data, as well as the inverter by implementing these MPP formulae to the Photovoltaic system model. Such grids oscillations are employed to control the inverter’s pulse-width modulation (PWM) inputs in a suitable manner. IGBTs to synchronize the simulating inverter to the grids. For the system, a simulation model built on Matlab/Simulink is created. To evaluate the total system performance, the simulation results are shown in this paper.
