Abstract:

Reactive power optimization problem play a major role in operation and control of power system. In this research a new natural inspired algorithm called Enhanced Krill Herd algorithm is utilized to solve the reactive power problem. Krill Herd algorithm is based on herd behavior of Krill individuals. The minimum distance of each individual Krill from food and from utmost concentration of the herd are considered as the main assignment for the Krill movement. The location of every krill in time period is dependent on persuaded movement of other Krill’s, foraging movement and physical dissemination. in this paper krill herd algorithm is enhanced by integrating with chaos theory and the logistic chaotic mapping is used in physical dissemination. Thus the Enhanced Krill Herd algorithm (EKHA) is used to solve the reactive power problem and the validity of the algorithm has been tested in standard IEEE 57 and 118 bus test systems. Simulation study shows the better performance of the proposed algorithm.
