Abstract
This research work presents development of Firefly algorithm (FA) and application of voltage
stability index (VSI) for optimal planning of Distribution Generation (DG) in an unbalanced threephase
distribution network. The VSI was used to find the DG location while the FA was used for
the DG sizing. The developed method was implemented on standard IEEE 37-bus Radial
distribution network test system and a local 19-bus Mahuta feeder. The results obtained from the
IEEE 37-bus were validated by comparing with a similar work. For the standard IEEE 37-bus
unbalanced radial distribution network (URDN), the total power loss obtained are 31.3543 kW and
15.2829 kVAr for active and reactive power respectively without DG in the network. When the
developed method is applied, a DG optimal location was found at bus 34 and a DG size of 356 kW
and 170 kVAr for active and reactive respectively are obtained. The active and reactive power loss
were found to be 19.8329 kW and 10.0014 kVAr respectively. The developed method recorded a
loss reduction of 36.75% and 34.56% for both active and reactive power respectively over the base
case. Also, the maximum loadability of the network was found to be 18% and 8% of the initial
loading with and without DG respectively. For the 19-bus Mahuta feeder, the location for the DG
is bus 17 and the DG size of 201.58 kW and 115 kVAr are obtained for active and reactive power
respectively. A power loss reduction of 4.48% and 5.62% for active and reactive power were
recorded over the base case respectively. The maximum loadability of the network for both the
developed method and base case were found to be 119% of the initial loading. When compared with research on similar work, the developed method achieved a loss reduction of 8.14% and 30.42% for active and reactive power respectively over the method applied in the work.
