Thus, these results indicate the interaction with the public grid is reduced at peak, shoulder, and valley hours in the energy system with ESS. Further, greater amount of renewable energy electricity is stored by ESS with the proposed strategy than with the common strategy at the shoulder and valley hour.
Small off-grid energy storage systems are used in remote areas that cannot be reached by the power grid. There are power shortages due to inadequate grid support, but at the same time, these areas are often rich in
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
For smaller grids and off-grid the added value of energy storage goes further than just grid balance: power quality issues and power reliability are also addressed [17], [22]. Power quality is the ability of the supplied electricity on the distribution grid to adhere to specified peak levels and standard voltage levels.
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.
