提出了基于模拟-优化模式的混联供水水库群联合优化调度规则求解框架。首先,通过构建虚拟聚合水库,编制联合调度图,以做出水库群对各用水户的供水方案;其次,通过优化成员水库供水任务分配因子,并结合供水水库群常规调度规则,实现共同供水任务在水库间的优化分配。采用改进粒子群算法(NSPSO)对观音阁-葠窝-汤河水库群联合供水调度模型决策变量(联合调度图调度线位置和成员水库供水任务分配因子)进行多目标优化,分析联合供水调度过程中目标之间的竞争关系,检验联合调度规则的合理性与有效性以及NSPSO算法的优化效率。
This paper proposes a model framework to determine joint operation rule for multi-reservoir water supply system based on the model of simulation and optimization. The procedure to employ this model framework includes: (1) determining water-supply amount for all water users by a piece of combined rule curves based on the constructed virtual aggregation reservoir, (2) achieving the optimal allocation of water-supply muhi-reservior. The NSPSO (Non-dominated Sorting Particle Swarm Optimization) algorithm is employed to optimize the combined rule curves and allocation ratios for Guanyinge-Shenwo-Tanghe water-supply system and the multi-objective competitive relationship is also analyzed. The results show that both joint operation rule and NSPSO are effective and reasonable for solving multi-reservoirs water supply operation problems.
