Similarly, an iterative
process is carried for 118 bus and 300 bus test systems which results
population size of 30 and itmax 30
for 118-bus test system. While for
300-bus test system, it is found that a population size of 30 and itmax 40 gives promising results. With increase in population size beyond 30 and itmax 40 in 300-bus test system does
not improve the solution rather computational time increases.
