Medium-and-long term generation scheduling compilation method of transverse rolling and vertical leveling in 'fair-and-square' mode

一种“三公”模式下横向滚动纵向调平的中长期发电计划编制方法

Abstract

The present invention relates to a medium-and-long term generation scheduling compilation method of transverse rolling and vertical leveling in a 'fair-and-square' mode. The method comprises: (1) building a mathematics model; (2) performing space adjustment calculation of the year radix electric quantity of each power plant; (3) performing month division of the year radix electric quantity after adjustment; and (4) performing fine tuning of the month plan result. The medium-and-long term generation scheduling compilation method of transverse rolling and vertical leveling in a 'fair-and-square' mode provides a combined generation scheduling compilation method of radix electric quantity and transaction electric quantity, the minimum year electric quantity progress deviation between power plants is taken as a target and the generation and electricity consumption balance, the maintenance scheduling, the power transmission capability and the fuel supply of each residual month of the year are taken as constraint to build the iteration optimization method of the electric quantity scheduling between months and power plants, and therefore the month rolling optimization of the medium-and-long term generation scheduling at the equal progress is realized, and the problem of the year electric quantity progress deviation control in the dynamic changing of factors such as radix electric quantity, fuel supply and the like in the medium-and-long term electric power transaction operation.
本发明涉及一种“三公”模式下横向滚动纵向调平的中长期发电计划编制方法,其特征在于,所述方法包括:(1)建立数学模型;(2)各电厂年度基数电量空间调整计算;(3)调整后年度基数剩余电量再分月;(4)月度计划结果微调。本发明提供了一种“三公”模式下横向滚动纵向调平的中长期发电计划编制方法,提出基数电量和交易电量的联合发电计划编制方法,以电厂间全年电量进度偏差最小为目标,以年度剩余各月的发用电平衡、检修计划、输电能力、燃料供应为约束,建立支持各月间及电厂间电量计划的迭代优化方法,实现等进度中长期发电计划的月度滚动优化,解决了中长期电力交易运营中基数电量、燃料供应等多种因素动态变化情况下的年度电量进度偏差控制问题。
