Wolf Search Algorithm for Solving Optimal Reactive Power Dispatch Problem

Abstract

This paper proposes a new heuristic algorithm that is enthused by the black hole phenomenon called as Black Hole Algorithm (BHA) used for solving the multi-objective reactive power dispatch problem. The Black Hole Algorithm (BHA) starts with a preliminary population of contestant solutions to an optimization problem. For all iteration of the black hole algorithm, the most excellent candidate is preferred to be the black hole, which followed by pulling further candidates around it, called stars. If a star move very close to the black hole, it will be swallowed by the black hole and is disappeared everlastingly. In such a case, a fresh star - candidate solution is arbitrarily generated and positioned in the search space and starts a fresh search.In order to evaluate the efficiency of the proposed algorithm; it has been tested on standard IEEE 30 bus system and compared to other specified algorithms. Simulation results show that BHA is superior to other algorithms in reducing the real power loss and improving the voltage stability.
