The group standard of China Electrotechnical Society “Testing Specifications for Monitoring Systems of Electrochemical Energy Storage Power Stations” was proposed by China Electrotechnical Society and drafted and compiled by State Grid Comprehensive Energy Services Group Co., Ltd. and other units.
　　

This standard stipulates the testing conditions, testing contents and testing methods of electrochemical energy storage power station monitoring systems, and is applicable to the testing of electrochemical energy storage power station monitoring systems connected to the power grid through voltage levels of 35kV and above.
　　
Standard setting background
　　
Energy storage is a key supporting technology for building comprehensive energy services, and an important part of building a wide-area ubiquitous, friendly interactive, and open shared energy Internet. Battery energy storage technology has developed rapidly in recent years. Due to its advantages such as high energy density, small footprint, high efficiency, short construction period, and strong station site adaptability, it has broad application prospects in power systems in the future and is the future energy storage technology. Development trends and research hotspots.
　　
However, at present, there are more than a hundred relevant standards in the field of energy storage in China. The current standard system focuses on standards such as design, manufacturing, testing, operation and maintenance, and safety. The standards for monitoring systems of electrochemical energy storage power stations are mainly concentrated on the technical requirements of the equipment itself. Standardization work on testing and testing of monitoring systems of electrochemical energy storage power stations has not yet been carried out, and relevant standards research has not yet been carried out and there are serious deficiencies. The lag or even lack of corresponding standards has become a key issue restricting the progress of the energy storage system industry.
