Dynamic analysis of an insulated distribution network

Abstract

This paper presents dynamic analysis of an isolated distribution network. This study has been carried out in a project looking at the consequences of a high penetration of distributed energy resources (DER) and distributed generation (DG). A network of a village (200 customers) in isolated mode is used for the study with DER connected to network via inverters such as microturbines, fuel cells and storage device. Several scenarios were used to dynamic simulations such as load and generation variation, starting of LV motor and short circuit. Influences of various coordinated controls and operating modes on dynamic behaviours are investigated. The results of this study can be used to specify the service systems in the future.
