Optimal placement of capacitor banks for power loss minimization in transmission systems using fuzzy logic
Debashish Bhowmik1, Pushpa Gaur2.
In a power system, it is essential to retain the voltage under permissible limit and
to deliver active power through transmission lines. This paper presents a method
to identify the optimal location and sizing of capacitors in a system for refining
the voltage profile and curtailing system losses. There are two important tasks to
be accomplished in this work, one is to determine the size of the capacitor to be
placed on the bus and the other is to determine the location of the capacitor in the
system. Firstly, the size of the capacitors to be installed is estimated. Then, the
calculation of power loss indices (PLI) is done with the help of the estimated size
of capacitors. The PLI and per unit nodal voltage are given as input to the fuzzy
expert system (FES) for determining the suitability index, which will decide the
most suitable location for capacitor placement. Newton-Raphson method for load
flow analysis is carried out to find the voltages at each node and the system losses.
The overall reliability and accuracy of the proposed method is validated by
testing on three different IEEE test bus systems.
