Abstract This paper proposes an analytical approach for reconfiguration simultaneously with DG hosting (RSDG) to reduce losses in the radial distribution networks (RDNs). Previous researches have mainly utilized Artificial Intelligence (AI) techniques that need dramatic computational efforts and may lead to local-optima. Through an extensive circuit analysis new terms called “Diff and Pivot” are proposed based on analytical formulations. The diff value represents the difference between the maximum loss reduction caused by a DG placed at a bus and the previous bus. Pivot relates diff values at every two successive branches. An algorithm named Pivot for Simultaneous Reconfiguration and DG Hosting (PSRH) is developed. For verification, PSRH is applied to IEEE-33, IEEE-69, and practical 84-bus RDNs and results are compared to AI techniques. Deduced outcomes are very encouraging with fewer computational steps. Moreover, the compromised solution of PSRH is superior when considering the outages of DGs as PV modules at night.
