Analysis of the DG in a network in Angola based on the IEEE 14-bus system

Abstract

Distributed Generation (DG) has become the main investment of power systems worldwide. This work analyzes the impact of DG on a power system in Angola based on the IEEE 14-bus test, using Matlab/Simulink software. As a result, it was noticed that, despite the increase in the generation capacity, DG causes changes in the voltage of the cutting system due to the change in the active and reactive flows. The critical situation is detected when there is maximum generation in scattering with minimum load, and unbalanced changes may occur in the shear levels of the bars, as well as influencing the recovery of the system when subject to a contingency situation. This work aims to provide initial studies on the impact caused by the introduction of DG in Angola, to show the need to prepare the system to receive this new technology in collaboration with the development of the country.
