Coupling modeling method for hydropower station power generated output scheme making and optimal load distribution

Abstract

The invention provides a coupling modeling method for hydropower station generated output scheme making and optimal load distribution. The method includes the steps that a hydropower station generated output scheme model is established with the maximum peak-load regulating capacity benefit as the target, and a in-plant set load optimal distribution model is established with the minimum water consumption as the target; the hydropower station generated output scheme model is solved, so that a hydropower station initial generated output scheme is obtained; the hydropower station initial generated output scheme serves as input of the in-plant set load optimal distribution model, simulation calculation is performed on the in-plant set load optimal distribution model, algorithm loop iteration and model trace netting correction are performed on the hydropower station initial generated output scheme through an integrated self-adapting adjustment mode, and coupled output is a final hydropower station generated output scheme. Integrated seamless coupling operation of hydropower station generated output scheme making and in-plant set load optimal distribution is achieved, wherein the hydropower station generated output scheme has the self-adapting adjustment characteristic, and the fine hydropower station generated output scheme is obtained under the condition that in-plant set load optimal distribution is met.

Description

technical field [0001] The invention belongs to the technical field of hydropower energy utilization, and in particular relates to a coupling modeling method for generation output scheme production and optimal load distribution of a hydropower station. Background technique [0002] The working process of the existing hydropower station is mainly as follows: (1) In the stage of power generation planning, the water dispatching department of the hydropower station combines the load characteristics of the power grid, with the goal of maximizing power generation, power generation efficiency, or peak shaving, and reasonably arranges mid-term scheduling and allocation to Short-term available water, and give the power generation output plan, and then report the power generation output plan to the electric dispatch department; (2) The electric dispatch department corrects the power generation output plan reported by the hydropower station, obtains the load task, and sends it to the hy...

Problems solved by technology

[0003] It can be seen from the above that the existing technology considers the production of hydropower generation output schemes or the optimal distribution of unit loads in the plant, and the main problems are as follows: (1) The process of making the power generation output schemes of hydropower stations does not consider the impact of the optimal distribution of unit loads in the plant. The influence of the results of the power generation output plan of the hydropower station leads to the proposed power generation proposal not fully meeting the dispatching requirements, and there is a defect that the power generation planning stage is out of touch with the power generation task execution process, and the use is limited

(2) In order to meet the minimum discharge flow and grid load requirements of the hydropower station, the water dispatching department and the electric dispatching department of the hydropower station often need to communicate and adjust repeatedly. The cumbersome procedures and calculations greatly reduce the work efficiency and quality of the dispatcher
