Energy storage is an important link for the grid to efficiently accept new energy, which can significantly improve the consumption of new energy electricity such as wind and photovoltaics by the power grid, ensuring the safe and reliable operation of the grid system, but energy storage is a high-cost resource.
The economic effect of energy storage construction has received increasing attention in recent years, as the use of renewable energy sources has grown, and the need for reliable and flexible power systems has become more pressing.
Overall, the available literature suggests that energy storage construction can have significant economic benefits, including reduced costs of power generation, improved reliability of the power grid, and reduced carbon emissions. However, the existing research has mainly focused on the energy sector in a national or global region.
In this case, the energy storage side connects the source and load ends, which needs to fully meet the demand for output storage on the power side and provide enough electricity to the load side, so a large enough energy storage capacity configuration is a must.
