Capacitor placement in distribution systems using fuzzy technique

A new approach using fuzzy sets theory and heuristic rules is used to determine the optimal number, size, and location of capacitors to place in a distribution system. The use of fuzzy sets theory is utilized for the decision of candidate nodes for the installation of capacitors by reconciling the degree of reactive power loss and the voltage sensitivity. This algorithm is applied to a practical case system and its results are compared with those generated by another nonfuzzy method.
