Optimal Capacitor Placement in a Radial Distribution System using Shuffled Frog Leaping and Particle Swarm Optimization Algorithms
ACEEE International Journal on Network Security, 3 (2): 5 (April 2012)
Abstract
This paper presents a new and efficient approach
for capacitor placement in radial distribution systems that
determine the optimal locations and size of capacitor with an
objective of improving the voltage profile and reduction of
power loss. The solution methodology has two parts: in part
one the loss sensitivity factors are used to select the candidate
locations for the capacitor placement and in part two a new
algorithm that employs Shuffle Frog Leaping Algorithm
(SFLA) and Particle Swarm Optimization are used to estimate
the optimal size of capacitors at the optimal buses determined
in part one. The main advantage of the proposed method is
that it does not require any external control parameters. The
other advantage is that it handles the objective function and
the constraints separately, avoiding the trouble to determine
the barrier factors. The proposed method is applied to 45-bus
radial distribution systems.
