A Levy Flight Based Voltage Particle Swarm Optimization for Multiple-Objective Mixed Cost-Effective Emission Dispatch

In this article, an optimization technique inspired from the nature has been incorporated with levy flight to resolve multiple-objective mixed cost-effective emission dispatch (MEED) challenges. An optimization technique named levy flight based voltage particle swarm optimization (LF-VPSO) technique has been introduced to maintain the adequate balance concerning the generation of power and emission of pollutants. MEED problem has been modeled using third order function. MEED objectives have been transformed into the one-objective function by considering penalty factor. The introduced method is executed with IEEE 30-bus test network. The simulation results obtained have been juxtaposed with theta particle swarm optimization (θ-PSO) method, multiple-objective particle swarm optimization (MOPSO) method and multiple-objective differential evolution particle swarm optimization method (MODE-PSO), which suggests that the proposed method gives the best solution amongst all the other reported optimization approaches. MATLAB R2016a platform has been used for simulation/programming.
