Abstract :Distributed generation insert ignore into journalissuearticles values(DG); is widely used to minimize total power losses in distribution networks. However, one of the problems of DG in a grid system is reverse current flow insert ignore into journalissuearticles values(RCF);, which is when the DG output becomes greater than the connected load. Therefore, this paper proposes a multiobjective artificial bee colony insert ignore into journalissuearticles values(MOABC); algorithm to determine the optimal network reconfiguration for reducing total RCF in DG. The proposed algorithm is tested on 33-bus radial distribution systems in two different scenarios, i.e. base case and with 50% load. The proposed technique can reduce reverse current by up to 93%; however, the total power loss in the system will increase by 7%. Therefore, a suitable weight value is needed in MOABC for balancing the effect of RCF and the power loss value.
