The BESS can store the energy of wind-PV farms and release the energy to the grid, and the energy can also flow directly from the wind-PV farms to the grid. When the wind-PV-BESS is connected to the grid, the BESS stores the energy of wind-PV farms at low/valley electricity price, releases the stored energy to the grid at high/peak …

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 [10]. Lai et al. [11] proposed a method that combines the dynamic thermal rating system with BESS to reduce system dispatch, load curtailment, and wind curtailment costs.
