Comparison of the performance of GA, DE, PSO and SA
algorithms in enhancement of TTC with FACTS device are
presented. These algorithms are tested with WSCC 9 bus
and IEEE 118 bus test system using the conventional
RPFNR and the proposed OABSS methods. Results
indicate that there is a considerable improvement in TTC
value as well as a huge reduction in computational time
when OABSS method is used when compared to RPFNR
since the later is more conservative. Though all the
optimization algorithms produce better results when it is
combined with OABSS when compared to RPFNR method,
DE outperforms GA, PSO and SA methods both in
enhancement of TTC and in computational efficacy. It is
also evident from the results that the percentage reduction
in CPU time using OABSS method increases with the
increase in size of the system when compared to that of
RPFNR method.
