Coordination of directional over-current relays in active distribution networks using generalised benders decomposition

Coordination of directional over-current relays (DOCRs) as the primary protection of meshed distribution networks is formulated as a mixed-integer non-linear programming (MINLP) problem. The coordination of DOCRs has been mainly accomplished using heuristic methods. Therefore, this study aims at proposing an efficient analytical tool for this problem. A two-stage analytical approach based on the g...
