Abstract :
Despite distribution systems usually operate radially, they may change the topology by opening or closing the switching equipment. This change can occur in two situations. Firstly, to maximize the networks´ electric configuration, to achieve lower voltage drop and loss indexes, as well as increases reliability. Secondly, to transfer load from a feeder to another one, as a result of some contingency or a planned disconnection. In both situations, one should take into account that multiple switchings in networks should cause disconnections at customers, during a short period of time, specially when the feeders are served by different-source substations. These interruptions cause undesirable energy continuity levels for customers. This motivates the present paper, whose proposal is the development of a methodology to analyze the technical feasibility of parallelisms in distribution networks by using the ATP program (Alternative Transient Program), thus avoiding disconnections at customers. As a result, case studies are presented.
