Comparative Study of Different Values of Inertia for Islanded Systems with Energy Storage Systems

This paper presents challenges related to voltage and frequency control for different values of inertia in islanded systems in the presence of synchronous generators, photovoltaic generation, and energy storage systems. The mathematical and physical basis of the problem is explained, and after that, a hypothetical rural network is proposed. This rural network is islanded from the utility grid and then analyzed for different 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 extremely important for the islanded network’s stability and resilience.
