Contest of strength game-based algorithm for decline of active power loss

Abstract

In this paper, contest of strength (COS) algorithm is proposed to solve the reactive power problem. It is inspired by the game of contest of strength and the algorithm imitates the features of the game. Each candidate solution is alike a team participating in a series of rope pulling competitions and based on exert pulling forces on each other the superiority of the solutions they exemplify. In this proposed algorithm the challenging teams are moving to the novel positions. Contest of strength (COS) algorithm maintains equal level of exploration and exploitation in search of near to global optimal solution in reactive power problem. Proposed contest of strength (COS) algorithm has been tested in standard IEEE 30, 57, 118 and practical 191 bus test systems and simulation results show clearly the better-quality performance of the projected algorithm in tumbling the real power loss.
