Distributed generation (DG) devices can be strategically placed in power systems for grid
reinforcement, minimizing real power losses, improving bus voltages and efficiency of
distribution system. The optimal DG placement (OPDG) method is used to provide the best
locations and sizes of DGs to optimize electrical distribution network operation taking into
account DG capacity and voltage constraints. In this paper, an efficient SPSO (Selective
Particle Swarm Optimization) algorithm is presented to solve the optimal DG placement …

For the purpose of improving the voltage profile and power losses reduction, this paper
proposes allocation and sizing of Distributed Generation (DG) in radial distribution system
(69 IEEE bus test system.). A simple and effective approach for power loss reduction (PLR)
value is employed for the allocation while the sizing was by using the results from the
allocation as local optimum in a modified PSO called Ranked Evolutionary particle swarm
optimization (REPSO) in order to obtain the global optimum. Load simulations in power flow …
