水光联合运行对梯级水电站生态调度影响研究
Study on impact of hydro-photovoltaic joint operation on ecological operation of cascade hydropower stations
摘要
Abstract
Ecological operation of hydropower stations is an important means to achieve a harmony between hydropower resource utilization and ecological environment protection.As more new energy bases are built,the joint operation of large-scale hydro-photovoltaic will significantly change the operations of hydropower stations,potentially affecting their ecological operation in ecological periods.This paper develops a multi-objective,two-layer nested ecological operation model for cascade hydropower stations,and explores the impact of such joint operation on the ecological operation of the stations.In this model,the upper-level simulates the dispatching process of hydropower stations for multi-day continuous water level rising,while the lower-level simulates the intra-day dispatching process considering photovoltaic integration.We have applied it as a case study to the Xiluodu-Xiangjiaba cascade hydropower stations located on the lower Jinsha River mainstream.Its simulations show that in different typical hydrological years,the joint operation does not significantly affect the multi-day rising required by drift eggs-producing fish species,and it can achieve more than two effective water rising events,each lasting up to 6 days.Compared with single hydropower generation,it can reduce outflow fluctuations by 8.9%to 28.3%.The findings help formulate ecological regulation and optimization schemes for cascade hydropower stations and integrated new energy sources.关键词
