The grid energy storage system regulates peak load and frequency, monitors load fluctuations in real time, rapidly responds to grid power dispatch, and improves grid frequency stability. This energy storage system is also designed to regulate reactive power compensation according to changes in the grid power factor, thus reducing power loss, and improving overall stability and reliability of the electrical grid.
Because the new energy power plant’s access to the grid aggravates power generation fluctuations and daily or seasonal peak-valley load difference is increasing, the grid energy storage system offers better value and is an efficient tool for adjustment of ancillary services. The grid energy storage system also improves marketability in the electric power industry.
