Reservoir hydropower station non-flood season joint optimization power generation scheduling method

Abstract

The invention provides a reservoir hydropower station non-flood season joint optimization power generation scheduling method. The method comprises the steps of establishing a whole non-flood season joint optimization scheduling dynamic planning module by predicting runoff, conducting scheduling based on the scheduling interval of a period of ten days, conducting re-amendment on a ten-day scheduling plan every day within a period of ten days according to an actual incoming flow of yesterday, after scheduling of each period of ten days is completed, optimization scheduling is conducted again according to a water level of a reservoir at the end of the period of ten days, and day-by-day amendment within the period of ten days is conducted continuously. According to the reservoir hydropower station non-flood season joint optimization power generation scheduling method, the optimization operation precision of a reservoir hydropower station is improved.

Description

technical field [0001] The invention relates to a dispatching method of a reservoir hydropower station, and more specifically relates to a method for jointly optimizing power generation dispatching of a reservoir hydropower station in non-flood seasons. Background technique [0002] Vigorously developing hydropower resources is an important strategy for China's energy resources. For my country's hydropower resources, they can be mainly divided into large and medium-sized hydropower stations and small hydropower stations. Among them, small hydropower stations are an important part of the development and utilization of my country's hydropower resources. So far, small The total installed capacity of hydropower stations accounts for about one-third of the installed capacity of hydropower, and the average annual power generation accounts for about one-fourth of the total annual hydropower generation. In terms of the number of power stations, the number of small hydropower stations ...

AI Technical Summary

Problems solved by technology

However, due to its scattered distribution, relatively backward social economy, and low management level, the current water resource utilization efficiency is significantly lower than that of medium and large hydropower stations

[0003] For reservoir-type hydropower stations, especially small-scale reservoir hydropower stations, due to their low degree of attention, power generation is still based on experience, and reservoir scheduling and hydropower station scheduling cannot be effectively coupled, resulting in certain inefficient operation of reservoir hydropower stations.
