Abstract

This work presents challenges related to voltage and frequency control for different values of inertia in islanded systems. The mathematical and physical basis of the problem are explained and, after that, a fictional rural network is proposed. The rural network is islanded from the utility grid and then analysed for differents types of generation and inertia values. Frequency and voltage of the network are compared. The results of this work enforce that firm energy generation and the sources inertia are extremally important for the islanded network's stability and safety.
