Increasing uncertainty in the modern power grid due to the variability of renewable energy resources has led to the widespread deployment of energy storage systems (ESSs). ESSs are flexible devices with high ramp rates that can help in maintaining a balance between generation and demand in the face of such uncertainty.
A further way to assess advantages of renewable energy systems may be to evaluate the pure energy ratio of the system. The term "energy ratio" is used to characterize relations between the energy input and output. Energy ratio is a ratio between the energy output and energy input according to the following equation; ER=Eo/Ei where.
