摘要：
The steady construction progress of AC/DC ultra-high voltage power grid and the rapid development of renewable energy, such as photovoltaic and wind power, increasingly bring pressures to peak regulation, frequency regulation, and voltage regulation in China.As an energy regulation technology in time dimension, electrochemical energy storage can be applied on a large scale, and its coordinated and optimized operation with “plant, network, charge” and other regulatory resources can effectively improve the emergency response and flexible regulation capacity of power grid. In this paper, the key technologies of large-scale energy storage peak regulation, frequency regulation, voltage regulation, frequency stability, and emergency recovery are introduced. Aiming at the failure of multi-infeed DC commutation in high voltage AC/DC hybrid power grid, the stability control and emergency recovery methods for dealing with emergency faults such as ultra-high voltage DC bipolar blockade are emphatically evaluated. The results of demonstration project construction and efficiency evaluation provide technical supports for the popularization and application of electrochemical energy storage in large power grids, and make AC/DC hybrid receiving-end power grids stronger and more intelligent. © 2020, High Voltage Engineering Editorial Department of CEPRI.
