摘要
Abstract
An economic dispatching model of power grid, in which the minimized generation cost is taken as objective and valve point effect of thermal units and operation constraints of power grid are taken into account is built, and a saturation and adaptive differential evolution (SADE) algorithm is proposed to solve the built model. To avoid the blindness in the search by the proposed SADE algorithm and to ensure that this algorithm can give priority to local optimal solution while the global optimal solution can be simultaneously considered, the adaptive adjustment strategy and the concept of saturation are led into the proposed SADE algorithm to prevent premature phenomena and speed up the convergence. Calculation results of 3-machine system, 13-machine system and 40-machine system verify the effectiveness of the proposed SADE algorithm.关键词
