This paper deals with the implementation of open loop control method for the grid connected inverter. 120-degree mode of inverter control is used in paper for simulation. The control method gives less THD in inverter output current and the inverter output current is in phase with grid voltage so it gives unity power factor operation. 1.
Different control strategies are used to control the grid connected inverter. Inverter output current and grid voltage should be in phase. To achieve unity PF. Inverter output current should be pure sinusoidal. Total Harmonic Distortion of inverter current should be less than 5%.

Do not leave the design powered when unattended. Grid connected inverters (GCI) are commonly used in applications such as photovoltaic inverters to generate a regulated AC current to feed into the grid. The control design of this type of inverter may be challenging as several algorithms are required to run the inverter.
