To increase loadability for the selected population size and itmax as in Section 4.2, a random population of fireflies of size 30*64 is generated.  Each firefly represents a small incremental load which can be added to the base load of P-Q buses. Consider each firefly and perform load flow analysis for load increase (incremental load +original load on PQ buses) as explained in Section 3.2. After given number of iterations of FA, the load is further increased using LIA as in Section 3.2. Finally total load obtained using FA and LIA in combination is as given below:
