|
Abstract:
摘要： 结合免疫系统的克隆选择原理和遗传进化机制,提出一种免疫克隆演化算法(Immune clonal evolutionary algorithm, ICEA)。ICEA建立克隆选择机制与演化机制的动态结合,提出动态免疫选择和自适应非均匀突变算子,针对动态经济调度(dynamic emission economic dispatch, DEED)问题特性引入不同的等式和不等式的约束修补策略,使其适合大规模约束的DEED问题求解。数值试验将ICEA应用于10机系统进行测试,并与同类算法展开比较。仿真结果表明,ICEA具有较好的收敛性和全局优化效果,获得的Pareto前沿具有较好的均匀性和延展性,该结果能为电力系统调度人员提供较为有效的调度决策方案。
Abstract: An immune clonal evolutionary algorithm(ICEA)was proposed by combining the clone selection principle of immune system and the evolution mechanism of genetic algorithm. A kind of dynamic immune selection strategy was introduced and a self-adaption non-uniform mutation operator was proposed. In order to make it suitable for solving dynamic emission economic dispatch(DEED)problem with many constrains, different repair strategies were introduced for the equality and inequality constrains of DEED model. In numerical experiments, ICEAs performance on 10-units system was tested, and several peer algorithms were compared. The simulation results indicated that ICEA had good convergence and global optimization efficiency. The uniformity and ductility of the Pareto optimal frontier obtained by ICEA was better than that of comparison algorithms. The Pareto optimal frontier could provide a more efficient scheduling decision-making approach for power system dispatcher
