Abstract: 

DISTRIBUTION NETWORK RECONFIGURATION MAY BE UTILIZED FOR MULTIPLE OBJECTIVES SUCH AS POWER LOSS MINIMIZATION, CUSTOMER SERVICE RESTORATION, LOAD BALANCING, VOLTAGE PROFILE IMPROVEMENT, MINIMIZATION OF SERVICE INTERRUPTION FREQUENCY AND SERVICE RELIABILITY ENHANCEMENT. DISTRIBUTION NETWORK RECONFIGURATION IS FORMULATED AS A CONSTRAINED MULTI OBJECTIVE PROBLEM. THERE ARE MULTIPLE OBJECTIVES AND SEVERAL OPERATIONAL AND NETWORK CONSTRAINTS IN THE PROBLEM. SO ACHIEVING A GLOBAL OPTIMUM SOLUTION FOR THE PROBLEM IS VERY HARD. HERETOFORE SEVERAL METHODS ARE DEVELOPED TO SOLVE THE PROBLEM BUT ALL OF THESE METHODS DON’T SEARCH ALL OF CONFIGURES BECAUSE OF THE NUMBER OF THE CONFIGURATIONS ARE EXTREME.
IN SPIT OF EXTENT NUMBERS OF THE CONFIGURATIONS FOR A DISTRIBUTION NETWORK AND SINCE DISTRIBUTION NETWORK STRUCTURES ARE PLANNED WITH LOW LOOPS AND MORE OF ITS LINES ARE SERIES CONNECTION, A FEW OF THEM ARE FEASIBLE. ALSO WE PROPOSE A METHOD TO DIRECTLY DETERMINE ALL FEASIBLE CONFIGURATIONS. THEN WE STUDY EACH OF THE FEASIBLE CONFIGURATIONS AND PERFORM SUITABLE QUICK LOAD FLOW FOR EACH OF THEM, AND THEN WE DETERMINE THE OPTIMUM CONFIGURE. THE PROPOSED METHOD HAS SOME ADVANTAGES. IN THIS METHOD WE CAN CONSIDER ALL OBJECTIVES AND CONSTRAINTS AND WE ACHIEVE GLOBAL OPTIMUM. THIS METHOD NEEDS ACCEPTABLE COMPUTATION TIME. THE PROPOSED METHOD HAS DONE ON A TYPICAL DISTRIBUTION NETWORK.
