Problems solved by technology

This invention considers the flood control index of the downstream river in detail, but does not include the implementation of river flood warning, relief of gate operating pressure and other supporting measures into the scope of the invention. If it is considered, the application will be more abundant

specific Embodiment approach

[0070] Taking a reservoir A in Sichuan, my country as an example, its coordinated operation strategy considering the river's flood demand is obtained. Three unfavorable typical working conditions that appear in the daily operation of reservoir A are respectively selected for method application. The specific implementation is as follows:

[0071] Step 1. Obtain data such as the forecast value of runoff entering the reservoir, the expected control value of the initial water level and the final reservoir water level of the day, and the output process of the hydropower station's power generation order on the day ( figure 1 The power generation dispatch order, forecasted water flow, and section inflow displayed in . Among them, the water level control is shown in Table 2.

Abstract

The invention provides a river flood control demand-considered reservoir coordinated dispatching strategy acquisition method, which comprises the following steps: Step I, acquiring a predicted value of an inflow runoff of a reservoir on the day, an expected control value of a water level at the end of the reservoir on the day and an output process of a power generation transfer order of a hydropower station on the day; Step II, constructing a river flood control demand-considered reservoir coordinated dispatching model by taking a graded flood control demand of a downstream river into account;Step III, on the basis of a target function, integrating a restriction condition in the coordinated dispatching model, and solving the constructed reservoir coordinated dispatching model by using a dynamic planning method; Step IV, providing key indicators from two aspects of the reservoir dispatching safety and the downstream river flood control safety to construct a safety evaluation indicatorsystem applicable to the characteristics of the coordinated dispatching model so as to comprehensively evaluate and feed back the safety of the obtained dispatching strategy. Compared with the prior art which does not consider the flood control demand of the downstream river in detail, the invention can provide a technical supporting scheme for promoting the river flood control safety management.

Description

technical field [0001] The invention relates to the technical field of water conservancy project management and hydropower energy dispatching, in particular to a method for obtaining a coordinated dispatching strategy of a reservoir taking into account the demand for river flood control. Background technique [0002] my country's economic situation has gradually become normalized, and the growth trend of annual electricity consumption in society has slowed down, but the peak-to-valley difference has widened year by year. With the continuous expansion of new energy sources such as wind power and photovoltaics, the power grid has a higher demand and dependence on power resources with peak-shaving capabilities. As a kind of green energy, hydropower has the characteristics of fast response and low operating cost. It is also an ideal peak-shaving power source. Giving full play to the excellent regulation performance of hydropower is of great significance to alleviate the peak-sha...
