All distribution network in South Korea are operated by Distribution Management System (DMS) of KEPCO. The DMS is configured by communication infrastructures, automatic switches, reclosers, and tie-switches on a radial system. Change of a tie-switch location determining a loss and a load capacity of each feeder can take an operational efficiency such as an economic advantage by loss minimization and load balancing in distribution automation system. Because customers' load patterns in a distribution network are different by time, region, seasons, and special events. Loss minimization and load balancing are considered by each but they were not considered together because their numerical unit criteria are different. Therefore, this paper proposes an algorithm in order to consider loss minimization and load balancing together. The proposed algorithm is verified by practical distribution networks of Jeju in South Korea. |
