Dynamic analysis of inverter dominated unbalanced LV micro-grids

This paper presents simulation of the dynamic behavior of low voltage micro-grids both under grid connected and autonomous operation. In LV micro-grids it is most likely that the sources participating in the system are connected to the network with inverters. This results in the formation of an inertia - less system. Modeling has to allow for the representation of all characteristic unbalances encountered in the LV network. The simulation is conducted using the electromagnetic transient analysis program EMTP-RV.
