Capacitor placements for distribution systems with fuzzy algorithm

Presents a fuzzy-based approach for capacitor placement in a distribution circuit. Two membership functions were defined for the voltage sensitivity and the real power loss. These membership functions greatly reduce the effort needed for finding the optimal locations via an exhaustive search. The whole problem is formulated as a fuzzy-set optimization problem to minimize the real power loss and the capacitor cost with voltage-limiting constraints. A distribution feeder was used to show the effectiveness of the proposed method
