由电力长远规划科研小组承担的水电部科技攻关项目“长江上中游干支流水能开发利用系统工程(A)”其研究成果——“多分区电力长期规划模型(IRELP/I)及其在试编长江中上游(四川)电力长期规划中的应用”获得了水电部1987年度科技进步二等奖,这是电力规划模型类课题唯一的二等奖项目。该项研究对水能资源开发和电力规划在采用现代方法方面取得了突破性的成果。模型构思在国际上首先作到了能充分反映水电站“群”的特点,水电能量可随不同开发方案由模型内生,从而使模型具有自动处理水电开发投资决策的功能;并首次实现多河流水能开发和多地区规划的整体优化。本模型已成功地应用于四川省电力长期规划工作。类似这样的模型及其应用,在国内外尚无先例。为进一步推进水能资源开发和电力规划工作中系统工程方法的应用,本刊特转载了该项研究结果。因篇幅所限,成果分“多分区电力长期规划模型(IRELP/I)”和“多分区电力长期规划模型(IRELP/I)在试编四川电力长期规划中的应用”两篇文章刊出,并在文字、内容上作了部分删减。 IRELP/I模型是一个层次模型,它由一个总体模型和两个模拟模型组成。第一层总体模型为混合整数规划模型,其功能是按设计枯水年优选电力系统的电源结构、河流水能开发时序及水、火电电源点。第二、三层是线性规划的模拟模型,其功能是优化水、火电站装机容量、煤矿建设规模、分区间电力潮流,该两层模型分别分析设计枯水年及中水年的情况,它们一般在总体模型优化的基础上作进一步优化,但也可对拟定的若干个宏观决策方案进行评价。 The long-term planning and research group by the Electric Power Research Department of the Ministry of Science and Technology project “the upper reaches of the Yangtze River tributaries of water systems development and utilization of water systems engineering” (A) “research results -” multi-division long-term power planning model (IRELP / I) The application of the long-term planning of the middle and upper reaches of the Yangtze River (Sichuan) won the second prize of the Ministry of Science and Technology 1987 for the progress of science and technology. This is the only second prize project of the power planning model project. This research has achieved breakthrough results in adopting modern approaches to hydropower development and power planning. The concept of the model was firstly made in the world to fully reflect the characteristics of “group” of hydropower stations. Hydropower energy can be endogenous to the model with different development plans so that the model has the function of automatically processing investment decisions in hydropower development. The first realization of multi- Development and multi-regional planning of the overall optimization. The model has been successfully applied to the long-term planning of Sichuan Electric Power. Similar to this model and its application, no precedent at home and abroad. To further promote the hydropower resources development and power planning work in the field of systems engineering methods, this article special reproduced the results of the study. Due to limited space, two articles, “IRELP / I” and “IRELP / I” applied in the long-term planning of Sichuan electric power, were published. And in the text, made a partial deletion of the content. The IRELP / I model is a hierarchical model consisting of an overall model and two simulation models. The first layer of the overall model for the mixed integer programming model, its function is based on the design of dry year power system power structure optimization, river water development timing and water, thermal power point. The second and third layers are linear programming simulation models whose functions are to optimize the installed capacity of water and thermal power plants, the scale of coal mine construction and the power flow among subzones. The two-layer model analyzes the design of dry years and middle-years of water respectively. It is generally further optimized on the basis of overall model optimization, but a number of proposed macro-decision schemes can also be evaluated.
