چکیده
This paper presents a new methodology using fuzzy and Real Coded Genetic Algorithm (RCGA) for the placement of capacitors on the primary feeders of the radial distribution systems to reduce the power losses and to improve the voltage profile. A two-stage methodology is used for the optimal capacitor placement problem. In the first stage, fuzzy approach is used to find the optimal capacitor locations and in the second stage, Real Coded Genetic Algorithm is used to find the sizes of the capacitors. The sizes of the capacitors corresponding to maximum annual savings are determined. The proposed method is tested on 15-bus, 34-bus and 69-bus test systems and the results are presented.
