Abstract

With large scale integration of micro-generation into low voltage grids, stability becomes an important issue for a Microgrid (MG). The unique nature of the MG requires that it becomes stable in both grid-connected and islanded modes. In grid-connected mode, the main grid guarantees the stability of MG but in islanded mode, the stability is related to all elements of the system and their control units. In this paper, the changes in droop coefficient influencing the frequency stability of the MG are investigated in islanded MG. The simulation results determine the new constraint for controllers in MG
