Energy storage equipment can realize the input and output regulation of electric energy at different time scales, which can effectively improve the operating characteristics of the system and meet the power and energy balance requirements of a smart grid. The application of different energy storage technologies in power systems is also different.
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.
Energy storage systems play a major role in smoothing the fluctuation of new energy output power, improving new energy consumption, reducing the deviation of the power generation plan, and improving the safe operation stability of the power grid. Specific classification scenarios are shown in Figure 4.
As fossil fuel generation is progressively replaced with intermittent and less predictable renewable energy generation to decarbonize the power system, Electrical energy storage (EES) technologies are increasingly required to address the supply-demand balance challenge over a wide range of timescales.
With the advancement of new energy storage technol-ogies, e.g. chemical batteries and flywheels, in recent years, they have been applied in power systems and their total installed capacity is increasing very fast. The large-scale development of REG and the application of new ESSs in power system are the two backgrounds of this book.
Energy storage technology is considered to be one of the key technologies to balance the intermittency of variable renewable energy to achieve high penetration. A connection structure diagram of an energy storage system and a public power grid is shown in Figure 2. Figure 2.
