Two of the main problems in this new scenario are the network reconfiguration and the loss allocation. This work presents a distribution systems graphic simulator, developed with reconfiguration functions and a special focus on loss allocation, both considering the presence of distributed generation. This simulator uses a fast and robust power flow algorithm based on the current summation backward-forward technique. Reconfiguration problem is solved through a heuristic methodology and the losses allocation function, based on the Zbus method, is presented as an attached result for each obtained configuration. Results are presented and discussed, remarking the easiness of analysis through the graphic simulator as an excellent tool for planning and operation engineers, and very useful for training. © 2004 IEEE.206-211engDistributed generationDistribution systemsLoss allocationNetwork reconfigurationAlgorithmsElectric industryElectric lossesElectric utilitiesProblem solvingSimulatorsGraphic simulatorsElectric power distributionTrabalho apresentado em evento10.1109/TDC.2004.1432379WOS:000228358400038Acesso aberto2-s2.0-227444472930614021283361265
