A methodology for the analysis of technical feasibility of distribution networks parallelism

Overhead distribution networks usually operate in radial topologies. The topology can be modified by opening or closing switches in the feeders during situations of normal operation, contingencies, or scheduled maneuvers. The parallelism of distribution networks is applied to transfer loads between feeders without the disconnection of feeders during the switching. This paper presents a methodology for modelling and analyzing the technical feasibility of distribution networks parallelism. In the proposed methodology, the parallelism is analyzed using the ATPDraw software. The applicability of the method is demonstrated through a case study using data from two feeders of the Electrical Energy Distribution State Company (CEEE-D). In order to validate the method, the parallelism of the case study was also executed by the Operation Center of CEEE-D and the results were compared with the computational simulations.
