Optimisation-based switch allocation to improve energy losses and service restoration in radial electrical distribution systems

This study presents a new methodology for the optimal allocation of switching devices in radial electrical distribution systems (EDSs). A specialised greedy randomised adaptive search procedure (GRASP) algorithm defines the location of a number of switching devices in order to simultaneously improve...
