Distribution Network Reconfiguration For Loss Reduction With Variable Demands

This paper presents a contribution to loss reduction in distribution systems, considering variable demands. Formulations for both fixed and variable demands are presented. Simple examples illustrate significant aspects of the problem with variable demands. Two algorithms are proposed to solve the loss reduction problem with fixed configuration for the whole planning period. © 2004 IEEE.384389Cavellucci, C., (1998) Buscas Informadas Baseadas em Grafos Para A Minimização das Perdas em Sistemas de Distribuição de Energia Elétrica, , Ph.D. dissertation, Electrical Engineering and Computation Faculty, UnicampBuch, J.B., Miller, R.D., Wheeler, J.E., Distribution system integrated voltage and reactive power control (1982) IEEE Transactions on Power Apparatus and Systems, pp. 284-289Merlin, A., Back, H., Search for a minimal-loss operating spanning tree configuration in an urban power distribution system Proc. 1975 PSCC 5th Power System Computation Conference, , Cambridge (UK), paper 1.2/6Lyra, C., Pissarra, C., Cavellucci, C., Redução de Perdas Na Distribuição de Energia Elétrica, , CBA 2000 Anais do XIII Congresso Brasileiro de AutomáticaShirmohammadi, D., Hong, H., (1989) Reconfiguration of Electric Distribution Networks for Resistive Line Losses Reduction, , IEEECivanlar, S., Grainger, J.J., Yin, H., Lee, S.S.H., Distribution feeder reconfiguration for loss reduction (1988) IEEE.
