Recently, the National Energy Administration approved the release of 8 smart energy meter standards, including the "Smart Energy Meter Functional Specification", further promoting the development of smart energy meter technology in China, improving the technical level of smart energy meter safety protection, anti-theft, and anti strong magnetic interference, and providing important technical support for the construction of smart grids.

Since 2009, intelligent energy meters in China have gradually replaced mechanical energy meters. Due to the lack of unified standards, smart energy meters have prominent problems such as unclear functional definitions, inconsistent appearance structures, multiple software versions, and incompatible communication protocols, which not only plague the design and production of electricity meter enterprises, but also affect the promotion and application of smart energy meters. In order to adapt to the construction of smart grids and the implementation of policies such as distributed energy access, energy efficiency measurement, and tiered electricity pricing, as well as the new requirements of users for the accuracy, reliability, and functionality of electric energy meters, the National Energy Administration organized the China Electricity Council and the Electric Power Industry Measurement Standardization Technical Committee to launch the development of technical specifications for smart electric energy meters in the energy industry in 2010. Based on the significant technological breakthroughs and practical experience achieved by State Grid Corporation of China, China Southern Power Grid Corporation, and Power Generation Group, a series of standards for smart energy meters in the energy industry have been formed through extensive discussions and extensive experimental verification.

The series of standards released this time are divided into four parts: function, type, technology, and safety certification, which are standardized and unified from the aspects of function definition, appearance structure, technical indicators, and testing and inspection. One is to clarify the definition and functions of smart energy meters. It can achieve various functions such as bidirectional and stepped metering of electric energy, load control, intelligent anti-theft, real-time monitoring, and information exchange; The second is to unify the appearance structure. The appearance design of smart energy meters has been reduced from thousands of types to four, greatly reducing the costs of design, development, and processing for energy meter enterprises; The third is to unify communication protocols and security standards. Realized bidirectional interaction between energy data collection and setting, with real-time collection of meter data, online payment, and energy information query functions, providing data support such as big data and cloud computing for smart home energy applications; The fourth is to innovate and propose multiple experimental methods such as the influence of power supply voltage. The establishment of a standardized testing method system has greatly improved product quality and reliability, enhancing the core competitiveness of smart energy meter enterprises in the international market.
