Impact of distributed generation on distribution networks

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.
