PEREZ ABRIL, Ignacio; HERRERA CASANOVA, Reinier  and  ALVAREZ FLEITES, Omar. Phase-balancing in distribution circuits of Santa Clara. Energética [online]. 2017, vol.38, n.3, pp.188-197. ISSN 1815-5901.

Primary distribution systems contain asymmetries in the lateral circuits and in the loads that are the source of the phase current unbalance. This work defines the phase balancing problem as the minimization of: the maximum current unbalance at selected points in the circuit for all possible operating conditions; the losses in the conductors of the primary feeder; and the number of reconnections required to achieve the two previous objectives. To solve this problem we have developed a Matlab application based on the non-dominated sorting genetic algorithm. The optimization program is complemented with an application developed to estimate the loads of the circuit from the available measurements. The results obtained in five circuits of distribution of the city of Santa Clara are presented to show the advantages of the presented approach

Keywords : distribution systems; genetic algorithm; optimization; phase balancing.
