Optimal capacitor placement determines the size and location of capacitors be installed on a radial distribution feeder. The capacitor placement problem is an optimization problem having an objective function composed of power losses subjected to bus voltage constraints that are commonly solved by employing a mathematical programming method. This book presents capacitor placement method which employs the differential evolution (DE) method and fuzzy logic for a given load pattern of the distribution system. The fuzzy logic reduces the number of alternatives to be examined and DE finds the...
