“…With the transition of the power source structure from stable traditional energy to more volatile new energy, one of the main characteristics of the new power system is the installation of energy storage on the power source side, which is an important means of maintaining the safe and stable operation of the new power system [11]. As of now, 23 provinces and regions in China have issued policies on the deployment of energy storage for new energy, with many cities requiring the construction of energy storage for distributed photovoltaics.…”

In order to ensure the stable operation of the power system, conventional voltage regulation methods include adjusting the generator excitation current and voltage regulation, adjusting the transformer turns ratio and voltage regulation, using SVC, STATCOM, synchronous phase shifter, etc. In terms of frequency regulation, the primary frequency regulation method of reducing the active power of multiple generators with lower frequency is adopted, or the secondary frequency regulation method using hydropower plants and medium-temperature and medium-pressure thermal power plants as frequency regulation plants is used. In terms of peak load regulation, thermal power units are often used as flexible peak regulation power sources, and the power output of thermal power units is controlled by load changes to achieve power balance. New power systems have the characteristics of large-scale integration of new energy, and random fluctuations in power on both the power generation and load sides. Energy storage, as a powerful new regulation means, is showing significant advantages with the support of national policies. This article first analyzes the energy storage technology-related policies issued by the government, and, combined with the characteristics of electrochemical energy storage technology in power auxiliary services such as voltage regulation, frequency regulation, and peak regulation in new power systems, puts forward prospects for the future application of electrochemical energy storage technology.
