Abstract :
[en] This paper deals with the management of voltage constraints in active distribution systems that host a
significant amount of distributed generation (DG) units. To this end we propose a centralized optimization
approach which aims at minimizing the amount of MW curtailment of non-firm DG to remove voltage constraints.
The salient feature of this approach is that it comprehensively and properly models the full variety of
possible control means (i.e. DG active/reactive power including DG shut-down, on load tap changing transformer
ratio, shunt capacitor, and remotely controlled switches or breakers), most of which having a discrete behavior.
We develop and compare the performances of two optimization models on a snapshot basis for various distribution
systems up to 1089 buses. In particular we show that the use of remotely controlled switches so as to transfer
DG between feeders in case of voltage constraints may lead to significant reduction of the DG curtailment.
