Abstract

This paper presents the steady state performance of active and reactive power flow between grid and inverter as voltage controller through a link inductor in distributed generating system. The inverter is synchronized and connected to the network through a link inductor that connecting the output terminal of inverter with the grid. In this paper, the design value of a link inductor between inverter and grid is also included. The design value of the link inductor is performed on two conditions, e.g., at the power angle 5 ° and approximately 90°. The link inductor value that gives the best performance on the system for the household scale DG application with 5 kW capacity is obtained at the small power angle 5°. With the appropriate design value of the link inductor in distributed generating system is presented in this paper, the best performance on the system can be obtained.
