Research on Power Benefits Assessment of SiPing Hydropower Station under the Operation of Sanliping Hydropower Station

In order to research on the effect on the hydropower benefits of SiPing Hydropower station by SaLiPing hydropower station in operation, cascaded optimal operation model has been established, with the objective function of maximizing minimum power and maximizing the generated energy capacity respectively, 0.5 times power probability is selected as system power constraint. The hydropower benefits is SiPing hydropower station is calculated before and after SanLiPing in operation. The result shows that after SanLiPing in operation, the hydropower benefits in SiPing are improved through the compensation of SanLiPing, as well as its flood control condition, brought huge economic benefits to cascaded hydropower stations.
