Abstract

As a consequence of the growing importance of distributed generation (DG) it´s very important to study the distribution network behavior. In this paper, voltage profile and gradient are analyzed taking in account power in-feed/out-feed of DG. The influence of reactive power requirements on the network voltage levels, based in the comparison of software simulation results with real-life behavior, are also studied. This paper equally analyzes the impact of DG on the substation transformers taps changers, with and without DG. Finally, it´s analyzed the impact of DG on protection systems functioning in a 60 kV network.
