Energy storage systems: A review of the technology and its application in power systems

Increasing implementation of renewable energy sources within power systems means that the use of energy storage technologies will be ever more important for system stability and power quality purposes. A range of energy storage technologies currently exist, ranging from low-power, short term technologies such as capacitors to long-term high power systems such as Pumped Hydro. Future developments such as the use of Carbon Nanotube technology within super-capacitors look set to bring improvements in power density, efficiency and lifetime.
