Simulation of synchronization photovoltaic system and low voltage grid

Abstract

In this research, the synchronization between the PV system and grid designed with synchronization parameters are voltage, frequency, and phase angle difference. As a result, by using a synchronization system, the PV system and grid could be parallelized and supplying power into the load at the same time. The synchronization method used is zero-crossing detection because it is simple than the other method. The synchronization system consists of several components; voltage detector, frequency detector, phase angle detector, and switch controller which all of them are controlled using the Arduino board. The switch controller will be functioned based on input from the detector to do synchronization or parallelize the PV system and grid. Testing is done by simulating running in Proteus. Based on the result of the simulation, the system is successful to do synchronization between the PV system and grid, it can be observed from the grid and PV inverter voltage graph and current which is measured from load, grid, and inverter.
