Energy storage is a valid way to ensure the actual-time power equilibrium of renewable energy systems. However, owing to the comparatively high cost of accumulation energy, the use of energy storage to equilibrium the system power will add to the system run cost, and the economy and dependability of the power system will be influenced. Therefore, in …
