Overview of modern applications of energy storage systems: part 1

The development of a country and the well-being of its citizens rely heavily on the availability of electricity. Further needs for the improvements of power quality and availability have been the cause for numerous studies and research efforts. During this expansion of energy availability, renewable energy (RE) sources have become popular. The widespread use of RE has however been delayed by its unreliability and fluctuations in output. This problem has however partly been solved by the implementation of energy storage systems (ESS).
