Abstract:
In this paper, an efficient BAT
optimization algorithm (BA) is proposed for
distribution system using automatic sectionalizing
switching operation in the large scale distribution
systems. A novel “Distributed power flow analysis”
has been derived for finding the electrical
quantities using the branch exchange method by a
forward backward sweep algorithm and to improve
the voltage stability. Network reconfiguration
attempts to determine a better solution in the
manner of a greatest-descent algorithm, but it
cannot give any guarantee for the convergence
property. Numerical examples demonstrated
through IEEE 33 bus and IEEE 69 bus system. The
validity and effectiveness of the proposed
methodology have been tested in TNEB 33 KV, 62
bus real time distribution systems. The test results
are minimizing the real power losses, minimizing
the deviation of node voltages, minimizing the
branch currents, minimizing the switching
operations and included Distribution generations
reveal that the proposed method yields optimal
reconfiguration and optimal conductor strength
with reduced computational burden. The result of
the proposed method provides a powerful
optimization solution. The algorithm is to avoid
escape from local minima by accepting
improvements in cost, but the use of this algorithm
is also responsible for an excessive computation
time.
