Abstract

Application of distributed generation to supply the demand of a diverse customer base has been gaining popularity. There will have a great impact current when distributed generation parallel to power grid, and the impact current have a significant effect on distribution system. According to the radial distribution system, the simulation model of distribution system which contains distributed generation was founded and the effects of impact current on voltage of distribution system were deeply studied in this paper. The results show that the voltage of distribution system will fluctuating follow impact current and maybe beyond the lower limit of safe operation. So the effects of distributed generation interconnections on voltage of distribution system should be considered when planning distributed generation and the margin of feeder voltage should be improved.
