The base values for voltage and power are 12.66 kV and 100 MV A. Each branch in the system has a sectionalizing switch for reconfiguration purpose. The load data are given in Table 1 and Table 2 provides branch data Savier Das 2007 . The initial statuses of all the sectionalizing switches switches No. 1-68 are closed while all the tie-switches switch No. 69-73 open. The total loads for this test system are 3 801.89 kW and 2 694.10 kVAr. The minimum and maximum voltages are set at 0.95 and 1.05 p.u. The maximum iteration for the Tabu search algorithm is 100. The fuzzy parameters associated with the three objectives are given in Table 3.
