ACOSTA-URREGO, CAMILO A.; HINCAPIE-ISAZA, RICARDO A.  and  GALLEGO-RENDON, RAMÓN A.. TECHNICAL LOSSES IDENTIFICATION IN LOW VOLTAGE DISTRIBUTION NETWORKS WITH GROUNDING SYSTEMS. Dyna rev.fac.nac.minas [online]. 2013, vol.80, n.181, pp.40-50. ISSN 0012-7353.

This paper proposes an approach to observe the impact of neutral wire and grounding systems on technical losses computation, using a three-phase four wire radial power flow. To ensure and accelerate the convergence of this algorithm, the Anderson mixing scheme technique is employed, giving both strength and efficiency to methodology. To validate the proposed methodology a colombian distribution system is used, in order to make a comparative analysis over different scenarios respect to traditional studies, which consider solidly grounded systems. The results obtained show that the grounding systems must not be neglected in the power flow analysis because the technical losses index can be wrong, and these losses have impact on losses reduction plans and electricity tariff structure, among others.

Keywords : Anderson mixing scheme; three-phase radial power flow; distribution networks; three-phase four wire systems.
