Description
Summary:An improved bare-bone multi-objective particle swarm optimization (IBBMOPSO) is proposed to solve the combined heat and power economic emission dispatch problems. To conquer the population diversity deficiency and premature convergence of bare-bone particle swarm optimization, IBBMOPSO integrates four improved strategies, that is, (i) a non-linear adaptive particle updating strategy is presented to automatically tune the weights of the personal best position (pbest) and the global best position (gbest), and to shrink the standard deviation for generating new particles; (ii) an improved strategy by comparing the sparsity of the pbest and the target particle instead of the domination is proposed to update the pbest; (iii) an improved strategy by selecting a random Pareto optimal solution from a newly filtered subset of the external archive is designed to determine the gbest for each target particle; and (iv) a modified strategy by combining the slope and the crowding distance is presented to determine the Pareto optimal frontier. IBBMOPSO is firstly validated by nine multi-objective benchmark test functions. Then, it is then applied to three test systems and the simulation results demonstrate that IBBMOPSO can achieve higher-quality dispatching schemes with lower generating fuel cost and less pollutant gas emission compared with other algorithms. •An improved bare-bone multi-objective particle swarm optimization algorithm is proposed.•A nonlinear adaptive particle updating strategy based on exponential function is proposed.•Improved strategies to update the pbest and gbest are proposed.•The slope method and crowding distance method are combined to determine the POF.•Benchmark test functions and three CHPEED problems are used to verify the performance.
