This paper presents, Ant Lion Optimizer (ALO), Flower Pollination algorithm (FPA), Whale Optimization Algorithm (WOA), Satin Bowerbird
Algorithm (SBO) and Moth Swarm Optimization(MSA) for determining the optimal location and sizing of DGs to minimize power losses in radial
distribution networks(RDN) and improve the voltage profile. DGs operating at different power factors are considered that is (unity and optimal). The
maintenance, operation and investment costs are formulated to form the total costs of DGs and also all the profits that DG Owner‟s (DGOs) are
considered at the same time. The proposed methods are implemented on IEEE 33, 69 and 119-bus test systems and the obtained results of the
proposed methods are compared with other popular methods available in the literature for validation purpose.
