水电基地常蓄结合式再开发多元结构与多样化调控模式
Multi-structure and diversified regulation modes of redeveloped hydropower base integrat-ing pumped storage hydropower plant
摘要
Abstract
Developing pumped storage hydropower plant(PSHP)based on existing hydropower plant to implement hydropower base redevelopment is of great significance for reducing the power curtailment of new energy.This paper primarily analyses the multi-structure of the redeveloped hydropower base and its underlying complex hydraulic con-nection,and proposes diversified regulation modes for the redeveloped hydropower base.Firstly,the article identifies the two modes of PSHP development:the individually-developed PSHP and cluster-based development PSHPs.The individually-developed PSHP relies on one on-stream reservoir.In contrast,the cluster-based development PSHPs relies on more on-stream reservoirs.Additionally,we clarify the structural characteristics of the PSHP from the view of unit type,PSHP type and the link type of PSHPs.Secondly,the paper discloses that the redeveloped hydropower base has the project feature of sharing storage capacity between PSHP and on-stream reservoir.Its operation feature focuses on the complex bidirectional hydraulic connection.The typical feature of cluster-based development PSHPs is the multi-link hydraulic connection and the reverse water accumulation effect.Thirdly,this study characterizes the diversified regulation modes of PSHP in terms of the timing,sequence and intensity of pumping and generating,and proposes synergetic cooperation model for the redeveloped hydropower base with maximum peak-shaving capability.Subsequently,taking the Warang and Lani PSHP as an example,results show that the redeveloped hydropower base reduces the power generation of the hydropower plant by 1％.It is worth noting that the cluster-based development of PSHPs raises the water level of the on-stream reservoir due to its multi-link hydraulic connection,and the reduction in power generation of conventional hydropower station is much less than that of the individually-developed PSHP mode.关键词
