Preparation study on large-scale PV system with pumped storage systems

The purpose of this paper is to study large-scale PV system with pumped storage systems (PSS). It is proposed a new method for PSS to store the electric power from PV system in the daytime and discharge in the nighttime as base power supply. Moreover, it should be concerned with the installing position of PSS, the capacity of PSS, the transmission capacity, the land and personnel cost, and the base power supply. The results indicate that PSS has possibility to be electric storage system in large-scale PV system. It can be used as base power supply to satisfy demand and to reduce or stop the output of nuclear or fuel oil electricity stations. It is possible that use base power supply from PV power instead of electricity from nuclear or fuel oil electric power stations.
