- Abstract:
-
Economic dispatch in an electric power environment is critical to reducing the cost of coal consumption and the emission of air pollutants during power generation. We propose a hybrid methodology that combines an intelligent-water-drops (IWD) algorithm with sequential quadratic programming (SQP) to improve the economic dispatch. Because of SQP’s weak global search capability, we use IWD to seek a global solution. In addition, the solution generated by the water droplets in each iteration is then taken as the initial solution of SQP, which is also slightly adjusted to improve the solution. We test the proposed approach by using a ten-unit system. In comparison with other methods that consider the valve-point effect, the proposed IWD-SQP method is feasible and effective.
