Integration of distributed generation units (DGs) in distribution systems aims to enhance the system performance. Location and the sizing are the two important factors on the network power loss. This work proposes a clustered firefly algorithm (CFFA) to reduce the distribution system loss, simultaneous optimal placement and sizing of the distributed generation resources in radial distribution systems studied. The simulation is done on IEEE-69 bus network in MATLAB software. The simulated results demonstrate the effectiveness of the proposed clustered firefly algorithm compared with other optimization algorithms.
