Grid-side energy storage applications refer to the deployment of large-capacity energy storage systems in the transmission and distribution links. By storing electricity during off-peak hours and releasing it during peak hours, it achieves "peak shaving and valley filling", balancing power supply and demand. At the same time, it can quickly respond to the frequency fluctuations of the power grid, assist in peak shaving and frequency regulation, alleviate the congestion of transmission lines, ensure the power supply of key loads, and also smooth out the grid connection fluctuations of new energy sources such as photovoltaic and wind power, enhance the consumption capacity of renewable energy, and optimize the operational efficiency and stability of the power grid.
Large-capacity energy storage systems can smoothly dispatch intermittent renewable energy sources, avoiding fluctuations in power output caused by weather changes, thereby enhancing the overall power supply quality and stability of the power grid.
It reduces the losses in the process of power transmission and distribution, improves the utilization efficiency of power equipment, and thereby lowers the costs of power grid construction and operation.
It can provide additional power support during peak electricity demand periods and store excess power during off-peak periods, thereby optimizing the allocation of power resources and enhancing the flexibility of power grid operation.
Energy storage systems can participate in auxiliary services of the power market, such as peak shaving and frequency regulation, and obtain profits through market mechanisms to enhance the economic viability and investment appeal of the project.
