| Summary: | In the operation of a distribution system, feeder load variation could often make an overloading of a feeder, and it may increase the real losses and the violation of the operation constraints of the feeder. To prevent this condition, it is good to reconfigurate the distribution network by changing the open or close status of the feeder switches in a way that a load transfer could be performed from a heavyload feeder to a lightload one so that a load balance could be reached.
This research presents a complete algorithm for the planning of distribution network reconfiguration for reduction of the real losses, which begin from forecasting the load, feeder load flow analysis, and finally distribution network reconfiguration. The three aspects were developed from previous work that was done by previous researchers.
The effectiveness of the algorithm was demonstrated by conducting it on local power company distribution system. It was found that the proposed algorithm could produce real losses reduction with the maximum saving value of 10.36 %, load balancing with the maximum depreciation value of load difference of 78.71 %, and with no operation constraints violation on the distribution system feeders, where the maximum depreciation or efficiency improvement of the feeder pair operation constraint indicators, which was for drop voltage reached a maximum value of 13.77 %, while for conductor current reaches 12.74 %. It could be concluded that the distribution network reconfiguration planning effort proposed in this research was aplicable to be used in the field since it could improve the eficiency of the case study.
