A survey on energy storage technologies in power systems

Abstract

The renewable energy sources are become an alternative for conventional power generating stations. Currently, in Canada 16.9% of total primary energy supply is met by the renewable energy sources. However, there is an increasing concern over renewable energy sources in power system due to its highly intermittent nature. This may cause problems such as stability, voltage regulation and other power quality issues. To mitigate the power quality issues, the energy storage systems are widely utilized in power system. This paper presents a brief review on various energy storage systems including mechanical, electrical, electrochemical and thermal storage systems.
