Electric energy storage can provide power on multiple time scales, respond quickly, and adjust flexibly. It is applied in various aspects of power system generation, transmission, distribution, and use, and is a key supporting technology for solving power balance problems and system stability risks caused by the integration of a large number of new energy sources into the grid.
Grid side energy storage improves the synergy between power and electricity balance, enhances the ability to absorb clean energy, improves the safe and stable operation level of the power grid, and improves the efficiency of power grid investment and operation. It plays a role in power grid peak regulation, frequency regulation, congestion relief, voltage support and reactive power control, emergency backup for faults, and other aspects, exerting a "four two pull a thousand pounds" effect. The organic combination of energy storage on the power supply side and the power supply improves the grid response characteristics and efficiency of the power supply, and alleviates the impact of the intermittency, randomness, and volatility of new energy on the grid. User side energy storage improves the quality of electricity consumption, reduces the peak capacity demand of the distribution network, compensates for the impact of distributed power generation output and emerging load randomness on the power grid, and drives the overall improvement of the power supply quality of the power grid.
With the rapid development of energy storage technology and the support of large-scale energy storage, the problems existing in the integration of new energy into the grid will be solved, promoting the realization of the energy revolution.
