Abstract

The invention discloses a cascade reservoir multi-objective optimization scheduling method based on an improved artificial bee colony algorithm. The method comprises the following steps that s11, the basic information data of a cascade reservoir system are acquired; s12, a multi-objective scheduling model including power generation, estuarine ecology and water supply is established according to the information of the reservoir system; and s13, the optimal scheduling scheme of the cascade reservoir system is solved by performing the improved artificial bee colony algorithm. Global optimization of the reservoir scheduling problem can be realized so that the calculation efficiency and accuracy can be enhanced, and a new approach can be provided for solving the multi-objective optimization scheduling problem of the cascade reservoir system.

Description

technical field [0001] The invention belongs to the field of reservoir scheduling in the field of water conservancy and hydropower, and relates to a multi-objective optimal scheduling method for cascade reservoirs based on an improved artificial bee colony algorithm. Background technique [0002] Reservoir optimal dispatching is a multi-objective, multi-constrained and complex water conservancy system optimal dispatching problem, especially for reservoir systems that undertake multiple tasks such as power generation, water supply, and ecology, it is difficult to solve the optimal dispatching problem. [0003] There are many rivers flowing into the sea in my country, and the interaction between the river and the sea is significant at the confluence of the river and the sea, forming a special and complex natural complex - the estuary. This area is often densely populated and economically developed. The stability of the estuary ecosystem is the sustainable development of society...
