摘要: 根据发电系统的特点,考虑多燃料和24 h预测负荷需求数据,建立了一种动态经济负荷分配的优化模型,提出了一种基于个体最优位置的多信息特征粒子群优化算法求解该问题。定义了质心位置和中值位置,采用了由个体最优位置,质心位置和中值位置构成新的速度更新公式。减少了求解复杂优化问题时的早熟现象,能够有效地解决求解动态经济负荷分配问题。通过对算例DED1的实验仿真,表明该算法能够有效求解DED问题,具有更好的优化性能。

Abstract: According to the characteristics of power system, an model of dynamic economic load dispatch based on multiple fuel resources and 24-hour forecasting load demand was established, and a particle swarm optimizer using multi-information characteristics of all personal-best information was proposed to solve it. In the algorithm, centroid position and median position were defined, and then the personal-best position, centroid position and median position was developed to modify the velocity update formula. The algorithm could reduce the premature phenomenon for solving complex optimization problems, and it could make effectively solve dynamic economic load dispatch. The simulation was conducted to optimize DED1 instance, and the results show that the algorithm can effectively solve the problem and has a better performance.

Key words: particle swarm optimization, economic load dispatch, information characteristics, power system
