Abstract

When distributed generators are connected to the grid, it is required that the system withstand the voltage dip caused by the grid failure. This is known as the low voltage ride through (LVRT). One of the effective choices to realize the LVRT is a grid connected inverter with virtual synchronous generator (VSG). This paper present a VSG control with capability for LVRT. By using this control, the operation of inverter can be continued even if a severe voltage dip at the grid has happened.
