DG Optimization in distribution network Using LRSF and FA: Case Studies

This paper proposes the use of the loss reduction sensitivity factor (LRSF) to determine the optimal position of the Distribution Generator (DG) in the distribution network, with the optimal size identified by the firefly algorithm (FA). The main objectives of the study are to minimize real power losses and improve voltage profiles in distribution networks. The optimization approach is applied to two case studies: the IEEE 33 bus network and a 32-bus network in Hebron City, Palestine, both with the inclusion of a photovoltaic (PV) system. Results show that placing the PV system at the optimal bus can reduce losses by 28.85% in the 33-bus network and 30.22% in the 32-bus network.
