Abstract: During dry water period,contradiction between the utilization of water quality and control of water level is concerned for the uncertainty of reservoir inflow,which is more significant for the limited regulation ability of quarterly and below regulating hydropower stations. In this paper,to utilize inflow energy and storage energy comprehensively,the loss of water level is represented with the loss of inflow energy and the objective of high efficient utilization is constructed,and a new optimal operation mode of hydropower station during dry water period is proposed. Through the comparison between loss of inflow energy and utilization of storage energy,loss of water level is represented with the loss of inflow energy and the objective of high efficient utilization is constructed,and a new optimal operation mode of hydropower station during dry water period is proposed. Through the comparison between loss of inflow energy and utilization of storage energy,optimal water level reduction plan is determined,and can provide decision reference for the coordination control on the utilization of water quality and water level.
