This Distributed generation (DG) is becoming more important due to the increase in the demands for electrical energy. Distribution system loss reduction is one of the prime objectives for planning of distributed generation. To minimize the losses, optimal sizing and location of distributed generation (DG) is critically important. In this thesis, the optimal DG placement and sizing problem is investigated using single-objective optimization problem, where the systems power losses are considered as the objective to be minimized. These problems are formulated as constrained linear optimization problems using the Sequential Quadratic Programming method (SQP). The proposed method is demonstrated on IEEE-15 bus and IEEE-33 bus radial distribution systems extensively used as examples in solving the optimal location and sizing problem of distributed generators. Simulation results with the DG shows improvement in terms of voltage profile enhancement and power losses reduction are obtained satisfactorily.
