There are various methods has been attained by integrating Distributed Generation (DG) in distribution systems. These methods help to reduce power losses and improve voltage profile of the system. Desirable results can also be achieved and enhanced if optimally sized DGs will be located in the systems. This paper presents a distribution generation (DG) allocation strategy to improve node voltage and power loss of radial distribution systems using flower pollination algorithm (FPA). The main objective is to minimize active power losses while keeping the voltage profiles in the network within specified limit.
