Abstract

With the development of society, there are new demands for the generate methods and the restriction for the impact on the environment. To improve the traditional centralized power generation pollution and low efficiency problems, the distributed generation has been presented. Although distributed power supply has various forms, when they cut-in the grid, they must use grid-connected inverters. The traditional inverter consumes large reactive power and produce harmonic seriously, causing the adverse effects on the grid. In recent years, the based on voltage external loop and current internal loop dual-loop grid-connected inverter gradually developed, in this paper we built the micro grid simulation model based on this kind of inverter in PSCAD/EMTDC and we configure the artificial settings to produce external load changes, and we discuss the parameters changes in the process. The results show that the inverter has good dynamic effect and prominent regulation effect.
