This paper proposes a method based on adapted Flower Pollination Algorithm (FPA) and the use of Sensitivity Analysis (SA) to determine the optimal allocation and sizing of Distributed Generation (DG) in radial distribution Systems. The most suitable set of buses for allocation is defined through SA at an initial stage. The FPA adaptation consists in splitting the search process between the allocation and sizing phases in order to increase the search efficiency. Tests on 33-bus and 69-bus radial network demonstrate that the method can provide significant reduction in active losses and improvement on voltage profile and compared with similar methods. In addition, a study considering variations in the DGs power factor (pf) highlights the benefits of carrying out the allocation process when the distributed generators also provide reactive power.
