Abstract

Based on the particularity of the safe and economic operation of hydropower plants,a unit commitment optimization model with the lowest water consumption is established and an improved binary harmony search algorithm is proposed. The heuristic repair strategy is used to handle the spinning reserve constraints and the minimum up and down time constraints,and the economic load dispatch problem is solved by querying the economic operation table. The actual load process of Zhelin Hydropower Plant is used as an example. The results show that the algorithm is simple and fast,and the optimization effect is good,and the optimal dispatch of the load between the units in different periods is improved,compared with the IBPSO and traditional DP method. Furthermore,the utilization rate of water is improved,and engineering practicability is strong.
