Abstract

The invention discloses a basin wind-light-water system multi-objective optimization scheduling method considering downstream ecology. The method comprises the steps of obtaining the basic informationof a cascade hydropower station; acquiring the basic information of the basin wind-solar power station; establishing a multi-objective power generation optimal scheduling mathematical model considering downstream ecology for a basin wind-light-water system objective and hard constraints according to the basin wind-light-hydropower station basic information; solving the established multi-objectivepower generation optimal scheduling mathematical model by adopting the improved AR-MOEA; and performing multi-attribute decision on the obtained non-dominated scheme by adopting SMAA-2. According tothe invention, the wind-solar-hydroelectric system is decoupled, so that the feasible solution is prevented from being damaged in the evolution process; a complete Pareto leading edge is obtained, a multi-attribute decision-making model of random multi-criterion acceptability analysis (SMAA)-2 capable of considering subjective willingness of a decision maker and uncertainty of attribute information is applied, more scheme sequencing information is provided for the decision maker, and the decision making can be conducted more scientifically and reasonably.

Description

technical field [0001] The invention relates to new energy and water conservancy and hydropower dispatching methods, in particular to a multi-objective optimal dispatching method for a river basin wind and water system considering downstream ecology. Background technique [0002] The output of wind power and photovoltaic power generation has the characteristics of randomness, volatility, and intermittency. Direct access to the Internet brings troubles to the operation of the power system, while hydropower can be stored and adjusted quickly, which can effectively alleviate the fluctuation of intermittent energy output to the power system. the impact. Therefore, it is of great significance to study hydropower compensation for wind and wind output. [0003] At present, most of the researches on the joint dispatching of wind-solar-hydropower systems in river basins focus on maximizing system benefits, stabilizing system output, and minimizing system operating costs. However, h...
