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).
