Problems solved by technology

[0003] Aiming at the problem that existing reservoir dispatching function optimization methods are difficult to realize the protection of river ecosystems, the technical problem to be solved in the present invention is to establish a new reservoir dispatching function optimization method. The reservoir dispatching function formulated based on this method can ensure that the operation of the reservoir is not stable. would cause drastic degradation of river ecosystems and maximize power generation from reservoir operations

Embodiment Construction

[0027] The present invention will be further described below with a reservoir in a certain river basin as an example.

[0028] 1. Formulate reservoir dispatching rules combining reservoir dispatching function and reservoir dispatching curve

[0029] When the water level in the flood season is higher than the flood limit water level of the reservoir, and the non-flood season water level is higher than the normal high water level, the reservoir operates according to the scheduling function of formula (1); when the reservoir water level is lower than the dead storage capacity water level, the discharge flow of the reservoir is zero; when the reservoir When the water level is between the flood limit water level line in the flood season, the normal high water level line and the dead storage capacity line in the non-flood season, the reservoir operates according to the scheduling function of formula (2).

[0030] 2. Determining the constraints of the optimized parameters

Abstract

The invention relates to a river ecosystem-oriented scheduling function optimization method of a power generation reservoir. The optimization method comprises the following steps of: firstly, combining a reservoir-scheduling curve and a scheduling function; drawing a reservoir-scheduling rule; then, confirming a river-quantifying hydrologic regime disturbing method and a hydrologic regime disturbing threshold; using the optimization of reservoir-scheduling generated energy as a target; optimizing the parameters of the scheduling function by applying a genetic algorithm to; when estimating the suitability of the genetic algorithm, bestowing a low-suitability value to individuals beyond a water regime disturbing threshold range so as to ensure the survival of the individuals in the hydrologic regime disturbing threshold range and further obtain an individual with the maximum generated energy in the hydrologic regime disturbing threshold range to be the reservoir-scheduling function ensuring the health of the river ecosystem and having the maximum generated energy. The invention can surely prevent the operation of the reservoir from causing the acute degeneration of the river ecosystem and optimize the generated energy of the reservoir.

Description

technical field [0001] The invention belongs to the field of water resource protection and water resource management, and relates to a method for optimizing the dispatching function of a power generation reservoir, in particular to a method for optimizing the dispatching function of a power generation reservoir facing river ecological system protection. Background technique [0002] The reservoir operation function is a basic tool to guide the operation and operation of the reservoir. A reasonable reservoir operation function can improve the social and economic benefits of the reservoir and effectively protect the river ecosystem. The methods for formulating reservoir dispatching functions can be divided into two categories: direct method and indirect method. The direct method is to first determine the form of the scheduling function, and then use some mathematical method to optimize the parameters of the scheduling function, and use the scheduling function corresponding to ...
