Abstract

One of the factors of high losses in the distribution network is its radial utilization. Therefore, reducing losses in distribution networks is one of the goals of operators. For this purpose, various measures have been thought out, among which, network reconfiguration is the most economical and fastest possible method. This process can reduce losses in the distribution network by adjusting the load of medium voltage distribution feeders. In addition, the increasing penetration of distributed generation (DG) can play a significant role. Finding suitable tie points in real distribution networks is difficult due to the large search space in which the number of impossible answers is much higher than the possible answers. This article aims to provide a method to find the optimal tie points among the existing tie points in the real medium voltage distribution in the presence/absence of DGs to reduce network losses. For this purpose, first, the basic challenges to solve this problem are identified and then an effective strategy is used based on the innovative dynamic switching set heuristic algorithm (DSSHA) considering the network constraints as a solution to the problem. Using this algorithm will limit the search space, reduce the volume of calculations and save time. This algorithm is written as a module with Python programming language, which can be implemented on any distribution network.
