Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
All storage technologies can reinforce the quality, stability and reliability of the grid electricity systems. However, the proper storage method should be selected based on several parameters, such as the capital and operational cost, the power density, the energy density, the lifetime and cycle life and the efficiency.
High-power storage systems have a dynamic impact on the flow of power within the grid, which improves the grid’s capacity to absorb and reduce oscillations and maintain overall stability and dependability. This support becomes crucial to keeping a steady and uninterrupted power supply and avoiding power outages .
For clarity, a brief explanation of several key terms regarding the characteristics of energy storage technologies is given in the sequel. Firstly, the self-discharge rate indicates the percentage of discharge during a period that a storage method is either not in use or in an open-circuit condition.
