Abstract

Recently, there is the largest (photovoltaic)PV-Hydro plant which has been set up as a utility-scale power generation in China. The purpose of this plant is to make the power grid accommodate more electricity from PV. In order to make more PV to be integrated into the power grid and expand its use, it is necessary to evaluate the relationship between PV and hydropower stations as hybrid stations. In this study, we have proposed an evaluation model based on cascade hydropower stations in China to estimate installation capability of PV for each reservoir, considering re-regulation volume and water supply relationship. The results indicate that the PV-Hydro power generation has a better effect on electricity generation during the day and night; PV installation on the upstream large hydropower station will affect the PV installation of the downstream small hydropower station and vice versa. However, the installation on the upstream small hydropower station will not have an effect on the one in the downstream large hydropower station; the maximum size of PV installation is 5926MW under constraints. Furthermore, applying PV-Hydro power generation has a better effect than applying them separately on reducing CO2emissions.
