LOADABILITY ASPECTS FOR MEDIUM VOLTAGE
DISTRIBUTION NETWORKS WITH INTEGRATION OF
DECENTRALIZED GENERATION
ABSTRACT
Decentralized Generation (DG) is an emerging concept in the electricity sector; its
integration into distribution networks may have a significant impact on different
technical aspects. The main aim of this paper is the investigation of the impact of
DG on the loadability of medium voltage distribution networks. The loadability is
evaluated in two aspects, the maximum loading according to the voltage limit (VL)
and the maximum loading according to the voltage stability limit (VSL). The im-
pact of the reactive power injection from DG on the system losses is also investi-
gated. These impacts are evaluated on a 15-node radial distribution network while
the DG is integrated at each node with different penetration levels and different
reactive power injections. The Continuation Power Flow (CPF) method is used to
evaluate the loadability with respect to the two aspects.
