High power loss and voltage instability are the main concerns in electrical power distribution due to load influence and single power source. Distributed generation (DG) is an emerging technology in the modernized power system, and it plays an important role in electrical power distribution system for loss reduction and voltage profile enhancement. This evolutionary has changed the radial distribution system from the single power source to multiple power sources. This paper presents the optimal placement and size of DG unit in radial distribution network using ant lion optimization (ALO). The objective function of this paper is to minimize the costs of annual power loss and operating of DG unit. The proposed algorithm is tested with 15 and 33 buses of radial distribution systems and ALO based optimal DG location and sizing resulted in the minimum total cost of power loss and operation cost of DG unit.
