[Abstract]:In view of the particularity of the optimal operation of hydropower units, a unit combination optimization model aiming at minimum water consumption is established, and an improved binary harmonic search algorithm is proposed to optimize the start-up and shutdown order of hydropower plant units. The heuristic repair strategy is used to deal with the constraints of rotating reserve capacity and minimum open / down time, and the load distribution among units in different periods is carried out by querying the summary table of economic operation. The actual load process of Zhelin Hydropower Plant is taken as an example and compared with the improved binary particle swarm optimization algorithm (IBPSO) and the traditional dynamic programming method (DP). The results show that the algorithm is simple and fast, has good optimization effect, realizes the optimal load distribution among units, improves the utilization ratio of water energy, and has strong engineering practicability.
