This paper proposes a multi-objective decomposition algorithm and parallel computing, based on normal boundary intersection (NBI) method and prime-dual interior point method, to minimize fuel consumption, emission of atmospheric pollutants and power purchase for large-scale power systems considering wind power penetration. The proposed algorithm firstly transforms a multi-objective optimization problem into a series of single objective optimization problems, and then decouples and reduces the correction equations of these single objective optimization problems based on the special structure of their coefficient matrices, at last decouples static and dynamic variables. Finally, a series of uniform distributed Pareto optimal sets, providing guidance for operators, is obtained rapidly by Matlab parallel computing platform. Computational results on a real provincial power system demonstrate that the proposed algorithm can obtain the Pareto optimal sets rapidly and efficiently to the multi-objective dynamic optimal dispatch problem.
