就如何确定最优的限制供水启动标准、停止条件以及限制供水量这三个限制供水规则研究的核心问题,建立了一种新的基于目标蓄水量的限制供水规则模型,该模型由两时段模型和目标蓄水量模拟优化模型构成,前者在给定的各时段目标蓄水量条件下求解限制供水规则,后者以解得的限制供水规则为基础优化各时段目标蓄水量.从理论上给出了考虑约束条件的限制供水规则解析表达式,同时采用主-从种群混合进化的粒子群算法对模型进行求解.在徐家河水库调度实例中,将模型与动态规划、标准运行策略和调度图方法调度结果进行了对比,结果表明了新模型的合理性及有效性.
On the core issues of how to determine the optimal water supply start-up standard, stop condition and water supply restriction, a new model of water supply restriction based on target water storage was established. The model consists of two periods Model and target water storage quantity simulation optimization model, the former solves the restricted water supply rule under the target water storage capacity for the given period, and the latter optimizes the target water storage capacity for each time based on the solution of the restricted water supply rules. From the theory The analytical expressions of restricted water supply rules with constraints are given and the particle swarm optimization algorithm is used to solve the model.Among the Xujiahe reservoir scheduling example, the model and dynamic programming, standard operation strategy and scheduling The results of the graph method scheduling are compared, the results show the rationality and effectiveness of the new model.
