Abstract

The synchronization between the grid and inverter is crucial for power sharing. By reconnecting the inverter to the electrical grid, it becomes possible to provide power in grid-off mode. Inverter-interfaced distributed generators (DGs) rely on control methods to drive the power devices in the inverter. A three-phase inverter produces output in terms of voltage, frequency, and phase, which can be matched with the electrical output using control methods. These control methods determine the pulse width modulation (PWM) pulses for driving the inverter. Simulations of the proposed systems with a grid-connected inverter are expressed through a MATLAB SIMULINK Model. Various algorithms generate different PWM pulses for the inverter. The differences between these algorithms are summarized in the results. Finally, the simulation results are analyzed across the load, total harmonic distortion (THD), error in grid voltage, and inverter voltage.
