ABSTRACT: This paper examines
the results of the distributed generation penetration in large-scale
medium-voltage power distribution networks. The network examined as a study
case consists of twenty one lines fed by three power substations. The injected
power comes mainly from photovoltaic units. Specifically, the influences of distributed generation on the network
branch currents, losses and voltage profile as well as on the short-circuit
level at the medium voltage busbars of the infeeding substations are examined according to international and
national standards.
The arising problems are explored and technical solutions are proposed. This
paper is a pilot application as general conclusions concerning the extended
distributed generation penetration in real power distribution networks are set out.
