More flexible resources are needed to supplement and complement regulation to maintain the safe and stable operation of the grid . Battery energy storage systems (BESS), as a practical and flexible regulation resource , have been widely studied and applied for the characteristics of energy time-shifting and power fast-accurate response .
The use of BESS to achieve energy balancing can reduce the peak-to-valley load difference and effectively relieve the peak regulation pressure of the grid . Lai et al. proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.
As mentioned earlier, due to the great potential of energy storage technology, there are many studies investigating its application in the grid.
Technically, the essence of BESS in grid PSVF and FR applications is to achieve active power charging and discharging regulation by controlling the converter, as shown in Fig. 1. In the application of PSVF, BESS is involved in peak regulation on hourly time scales. BESS is used as a power source to discharge when the grid load is at its peak.
The BESS's active power charging and discharging realizes a fast power response, effectively adjusting the grid frequency and improving power grid frequency stability . And there is also some research on ancillary services.
