This paper presents the development of a control model for inverter driven island grids. The herein presented structured approach creates a multi voltage source inverter model from a single inverter state space model and combines this with the node incidence matrix of a network into a compound model of an island grid. The presented approach allows to analyse arbitrary grid structures and different inverter models and it incorporates a large number of inverters. The model can be particularly used for ohmic-inductive low voltage lines. At the end of the article, a stability analysis of a sample network is presented. [less ▲]

This paper recapitulates an analytic control model for arbitrary island grids and presents findings on the dynamic behaviour of purely inverter driven island grids. Pole zero plots of different grid structures are presented and the influence of several inverter parameters on the grid stability is analysed. Findings show that for improved grid stability the inverter’s time constants should also relate to their rated power. Further it is shown how P-Q rotation in the droop control can improve the integration density of renewable power sources in the distribution grid. [less ▲]
