Abstract

The motivation to develop microgrids (MG), as a particular form of active networks is explained and presented as an effective solution for the control of grids. In MGs, with high level of penetration of Distributed Energy Resources, the stability becomes an important issue. Some control characteristics of elements such as droop coefficients in VSI highly affect voltage and frequency stability. In this paper, the changes in droop coefficient influencing the voltage stability of the microGrid are under investigation in islanded MG. The simulation results show the importance of the proposed limitation for the droop controller.
