Abstract

The invention discloses a cross-drainage-basin load distribution method of multi-stage inter-basin and intra-basin feedback iteration. In order to solve a distribution problem of the total load amongmultiple basin hydropower stations (groups), the method considers the water consumption rate and comprehensive utilization of reservoirs comprehensively as well as gives consideration to the short-term and long-term utilization of the reservoirs. According to the method, load are distributed to hydropower stations that do not have regulation capabilities basically and include daily regulation andrunoff hydropower stations, so that the waste water is minimized; and then the residual loads are allocated again among hydropower stations with regulation capabilities, wherein the priority power generation indexes of the hydropower stations are designed and a power generation sequence is determined based on consideration of combination of short-term and long-term utilization during allocation. Therefore, the automatic level of the cross-drainage-basin load distribution is improved; and the centralized and refined management level of the basin hydropower stations is improved.

Description

technical field [0001] The invention relates to an optimal distribution method suitable for daily total load among multiple river basins, belonging to the technical field of water conservancy and electric power. Background technique [0002] Under the background of the current power system reform, the thinking mode, working method and management system of power enterprises are facing new tests, and the competition will be more intense. Based on the existing production and operation data, use scientific optimization decision-making methods to optimize production and reduce It is an effective way to deepen the application of science and technology to reduce production costs and improve the economic benefits of power production. Power load allocation refers to the optimal distribution of the power generation of each power generation unit under the premise of a certain total load, and the selection of the optimal combination scheme that satisfies the objective function is an imp...
