Grid-Code for interconnection are being studied due to problems such as voltage drop in distributed generation connected to the grid, grid protection and power quality in the event of a low voltage accident. For the initial distributed generation, the Grid-code required to cut off electricity within the clear time in the event of a low voltage accident, but as the distributed generation expands, it is being amended to determine the inverter operation method according to the state of grid voltage and accident time. These Grid-code are amended by each country according to the respective country, and among them, Germany"s Grid-code require the most stringent standards. In this paper based on the Germany"s Grid-code. The existing PLL(Phase Locked Loop) control method has a problem in that it is difficult to accurately estimate the phase due to the very low system voltage in the event of a low voltage accident. To solve this problem, the proposed PLL control method using current information to obtain an accurate phase in the LVRT(Low Voltage Ride Through) situation is verified through simulation and experiment.
