Application of energy storage technology used in photovoltaic power generation system

Renewable energy needs the usage of energy storage technology to manufacture its energy utilization because of instability via environmental impact in generating electricity process. Therefore, energy storage technology plays an important role in the process of renewable utilization systems, many kinds of new energy technologies consider energy storage system as an part of their energy management as well as progress of corresponding technologies. This paper promotes the development of energy storage technology and application of two topological structures, expounds its the function in power system and comparison under various control methods.
