为求解大型水电站自动发电控制(automatic generation control,AGC)机组优化组合问题,提出一种多种群蚁群优化算法。同时,综合考虑水量、电量平衡,水库、机组运行限制等多重安全生产约束条件,提出了一种流量—水头—出力的循环迭代策略确定时段动态水头,并引入基于机组启停优先顺序表的系统备用容量修补技术,使水电站AGC机组运行时达到最优。将所提算法应用于葛洲坝水电站AGC机组优化组合,与其他求解方法对比表明所提算法求解精度高,求解速度快,具有较强的工程实用价值。
In order to solve the optimal combination of automatic generation control (AGC) generating units in large hydropower stations, a multi-species ant colony optimization algorithm is proposed. In the meantime, a cyclic iterative strategy of flow-head-output is proposed to determine the dynamic head of a period by comprehensively considering the constraints of multiple safety production such as water quantity, electricity balance, reservoir operation and unit operation limits, and the system based on the start-stop priority list Reserve capacity repair technology to optimize operation of hydropower AGC units. The proposed algorithm is applied to the optimization of AGC units in Gezhouba Hydropower Station. Comparing with other solving methods, it is shown that the proposed algorithm has high solution accuracy and high solution speed, and has strong engineering practical value.
