基于加速多蚁群算法的三峡水电站短期优化调度
Short-term optimal operation of Three Gorges Hydropower Station based on accelerated multiple ant colony algorithm
摘要
Abstract
To solve short-term optimal operation problem of the Three Gorges Hydropower Station,an improved ant colony al-gorithm with enhanced optimization capability called accelerated multiple ant colony algorithm(AMACA)was proposed.And an overall temporal and spatial search matrix was built by increasing the number of ant colony and dispatching every ant to every unit to work in a way of labor division and collaboration.Accelerated searching strategy was used to accelerate the starting time of searching processes of ant colonies generation by generation.Accelerated searching strategy realizes the partition of pheromone feedback intensity and improves global search capability of the algorithm.Local search strategy was used to realize small-scale optimization and to further improve the reliability of start-up and shutdown strategies and dispatching schemes for hydropower stations.Optimal distribution table was created ahead and called in main program to optimize the distribution of total load among units.The running results of AMACA in the Three Gorges Hydropower Station indicate that:fewer water consumption and better operation strategy were obtained using AMACA compared with GA,BACA and EACA under 77.00,86.00 m and 102.00 m water head.At the same time,loads of all units are in there stable operation regions using AMACA,which can avoid cavitation vibration,improve the stability of unit operation and improve the robustness of short-term optimal dispatching scheme.关键词
