摘　　要：探讨一种便于在线应用的火电企业负荷优化分配方法。在负荷优化分配中经常需要处理升降负荷速率的约束,由于需要关联前一时刻负荷优化结果,往往增加了优化算法的复杂性。借鉴动态规划的思想,采用遗传优化算法建立了最佳负荷分配表和处理升降负荷速率约束的优化策略,提出一种将寻优与分配分离的负荷优化分配计算方法。算例表明,新方法不仅具有与遗传优化一致的分配结果,且降低了优化分配的计算复杂性,具有实际应用价值。A load optimal distribution method that is convenient for online application in power plant was discussed in this paper.In the load optimal distribution,the rise or drop speed of load is limited.The complexity of optimal algorithm is increased since the former load optimal results should be related.Borrowing ideas from dynamic programming,an optimal load distribution table and optimal strategy of load speed limit were established using Genetic Algorithm（GA）.Moreover,a new method,separating seeks and distribution in load optimal,was proposed.An example is illustrated to show that this new method not only has the same distribution results with GA but also decreases the calculating complexity.It suggests that such method is valuable in practical application.
