Research and Discussion of Optimal Load Distribution in Power Plant Based on Speediness

在指出基于经济性的厂级负荷优化分配数学模型不能有助于电厂快速完成电网负荷需求调节的不足后,通过对机组完成负荷过程的分析,文章得出了理想状态下电厂完成电网分配负荷的最短时间,并进行了数学证明;在此基础上,建立了以快速完成电网负荷需求为目的的厂级负荷优化分配数学模型,从而为电厂快速完成电网负荷需求找到了科学的数学理论依据。接着本文详细介绍了基于动态规划求解的快速性负荷优化分配解决方案。最后本文给出算例,通过仿真对比,证明了基于经济性负荷优化分配数学模型在调节负荷速率上的不足,同时也证明了本文提出的基于快速性的厂级负荷优化分配数学模型的正确性和有效性。

It is indicated in the paper that there is deficiency of Plant Load Optimal Distribution Model （PLODM） based on economy, so it could not help power plants to speedily complete the demanded load points out that power plants for power grid. The paper can complete the demanded load by power grid. Upon the analysis of the process of units＇ accomplishing load and proof by mathematical means; on such basis, this paper established PLODM of speediness, which provided power plants with scientific Load Optimal Distribution Mathematical Proof to fast load completion. Moreover, this paper elaborates application of dynamic programming solution. Finally an example is given to show that PLODM based on economy is deficient in adjusting load speed, and PLODM based on speediness is correct and effective.
