This paper puts forth a model of optimal reservoir operation that uses particle swarm optimization(PSO) algorithm and takes the limited levels in main flood and post-flood seasons as coordination variables.This model was adopted to evaluate the impact of limited-storage level change on utilization ratio of reservoir water,long-term average annual power output and reservoir filling rate.By the results,higher operating levels are better,and in main flood season the impact on the power output and the utilization ratio are more considerable than that in post-flooding season.This conclusion is practically significant to study of benefit and risk of hydropower station.
