Abstract

The application of energy storage technology is equivalent to adding a “storage” effect between the power generation and the power load of the power system, so that the power generation and the power load are relieved and buffered to a certain extent. Therefore, the system is Power quality, stability, and reliable operation can all be significantly improved, and the operation of the power system can be well optimized. On the technical level, by controlling the power exchange device, the energy storage system based on energy storage technology can exchange fast and large-capacity active power/reactive power with the large power grid to maintain the basic balance between power generation and load of the power system, and the power system. The voltage and frequency can also be effectively guaranteed, improve the reliability of power supply and power quality, reduce or avoid the loss caused by grid reliability and power quality problems, and meet the high-spec power requirements of users; in addition, when an accident occurs in the power system, Energy storage technology can help the system to restart / black start, improve the system's rapid recovery capabilities.
