Resumen
Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) This paper proposes an effective technique to control the power flow among different phases of a three-phase four-wire distribution power system by means of single-phase converters arbitrarily connected among the phases. The aim is to enhance the power quality at the point-of-common-coupling of a microgrid, improve voltage profile through the lines, and reduce the overall distribution losses. The technique is based on a master/slave organization where the distributed single-phase converters act as slave units driven by a centralized master controller. Active, reactive, and unbalance power terms are processed by the master controller and shared proportionally among distributed energy resources to achieve the compensation target at the point-of-common-coupling. The proposed control technique is evaluated in simulation considering the model of a real urban power distribution grid under non-sinusoidal and asymmetrical voltage conditions. The main results, concerning both steady-state and transient conditions, are finally reported and discussed. 8 1 437 446 Sao Paulo Research Foundation [2013/21922-3, 2012/14014-0] National Council for Scientific and Technological Development [302257/2015-2] Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)
