Little attention has been paid to the integration of Distributed Gen-
erators or DGs and capacitor banks in radial distribution system to meet
the increased electricity demand and to improve the technical aspects
like power loss reduction, voltage profile improvement, etc. Such im-
provements involve major concerns such as finding the optimal sizing of
DGs and capacitor banks and their locations. This article presents the ap-
plication of two new optimization algorithms: Firefly Algorithm (FFA)
and Backtracking Search Algorithm (BSA) to solve the optimal place-
ment of both DG and fixed capacitor banks, in order to reduce the power
loss and improve voltage profile of distribution system. A detailed per-
formance analysis is carried out on 33-bus and 69-bus radial distribution
system to demonstrate the effectiveness of the proposed algorithms and
the results are compared with the Genetic Algorithm/Particle Swarm
Optimization (GA/ PSO), Imperial Competitive Algorithm/ Genetic Al-
gorithm (ICA/ GA) and Analytical approaches available in the literature.
