As can be seen in Table 3, for the power type and application time scale of energy storage, the current application of energy storage in the power grid mainly focuses on power frequency active regulation, especially in rapid frequency regulation, peak shaving and valley filling, and new energy grid-connected operation.
Under some conditions, excess renewable energy is produced and, without storage, is curtailed 2, 3; under others, demand is greater than generation from renewables. Grid-scale energy-storage (GSES) systems are therefore needed to store excess renewable energy to be released on demand, when power generation is insufficient 4.
Table 3. The status quo of energy storage functions in smart grids. The functions of the power generation side mainly include fast frequency regulation, the suppression of low-frequency oscillation, automatic generation control, smoothing new energy output fluctuations, new energy output plan tracking, new energy output climbing control, etc.
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.
The rise in renewable energy utilization is increasing demand for battery energy-storage technologies (BESTs). BESTs based on lithium-ion batteries are being developed and deployed. However, this technology alone does not meet all the requirements for grid-scale energy storage.
For integrating energy storage systems into a smart grid, the distributed control methods of ESS are also of vital importance. The study by proposed a hierarchical approach for modeling and optimizing power loss in distributed energy storage systems in DC microgrids, aiming to reduce the losses in DC microgrids.
