To analyze the results in detailed manner, proposed approach results are compared for PG, QG, PD, QD, voltage magnitude, voltage angle and losses with base case and DEPSO. It is clear from last column of Table 3 that the proposed approach increases loadability to 50.32% from base case while it is 42.32 % in DEPSO.  On comparing the real and reactive power losses with DEPSO, it is found that there is no significant difference between two methods while the proposed approach yields nearly 8% more load increase than DEPSO.
