PV connected Pumped-Hydro Storage System

Abstract

Storage systems are needed to increase the number of renewable energy sources that can be integrated into distribution systems in smart grids and to ensure the continuity of energy. Energy storage can support system operators and provide many services such as energy time shifting, capacity backup, outage management, transmission congestion relief and power quality improvements. Batteries and storage are used due to interruptions and waves in renewable energy sources such as wind and solar. In order to expand the use of clean energy and to ensure energy continuity, mechanical storage methods are emphasized in large power systems. Storage studies have been carried out to increase efficiency, reduce costs and improve storage time. In this study, the stages of the PV integrated system model of pumped hydro storage systems, which is one of the mechanical storage methods, will be mentioned.
