The research and development of smart grid standards is also a systematic project, which requires the full cooperation of all stakeholders and the adoption of a systematic approach to research and analysis in order to build a scientific and reasonable smart grid standards system. In the past few years, the development of smart grid at home and abroad has mainly experienced two stages. The first stage focuses on development planning, standard system preparation and standardization, and demonstration project construction, while the second stage focuses on the promotion and application of technology. The State Grid Corporation has basically completed the work of the first and second stages. In the first phase, it has formed a relatively perfect smart grid standard system and completed more than 300 demonstration projects; in the second phase, it has completed the large-scale promotion and application of new technologies, and only carried out demonstration projects for some technologies that lack business models or support from the corresponding policy mechanisms, such as automatic demand response, electric vehicle charging and discharging technology, smart home, and so on. In the third stage of development of smart grid construction, the State Grid Corporation in the development of smart grid standards development goal is to "improve the standard system, to ensure that the international leading", the focus of the work is to improve the smart grid standard system, and promote the internationalization of smart grid standards.

The new development situation provides opportunities for the development of smart grid technology: the government issued the "Guiding Opinions on Promoting the Development of Smart Grid", which is conducive to organizing and mobilizing all parties to carry out research on smart grid technology and standard development at the national level, and facilitating the formation of *** knowledge, *** with the promotion of the smart grid engineering and construction; the introduction of a new program of electric power reform for the implementation of the development of smart grid environment, demand response and automatic demand response to provide the best solution for the development of smart grid technology and the development of smart grid technology. The introduction of the new program of power reform provides a possibility for the implementation of demand response and automatic demand response in the environment of smart grid development; the development and wide application of big data and Internet technology provide new ideas and solutions for promoting the application of new energy power generation and electric vehicles, improving the management and utilization of grid assets, and improving energy efficiency. Standardization needs and technological development depend on each other, and the new development situation of smart grid also puts forward higher requirements for technical standards, and at the same time, it also provides more opportunities for emerging countries to play an important role in international smart grid standardization work, and to improve their influence and discourse power. Smart grid technology development and standardization under the new situation is also facing new challenges. As far as the technology itself is concerned, the complexity of smart grid has increased, such as: although big data provides new ideas and new methods for realizing the development goal of smart grid, big data technology itself is a comprehensive technology, and there are many obstacles to be overcome in the implementation of big data technology, including difficulties in data uploading caused by communication and information architecture that does not meet the consistency requirements; difficulties in data acquisition caused by the shaft-like system structure and the shaft-like management mode; difficulties in data modeling; difficulties in data access; and difficulties in data modeling caused by the vertical well-like system structure and vertical well-like management mode. data access difficulties; data fusion difficulties due to data model non-uniformity and data privacy and security issues. This not only involves the transformation and restructuring of the communication information system, but also requires the development of corresponding technical standards. The information physical system is one of the important theories to support the future development of smart grid and the realization of the energy Internet, and its technical research and standardization work has just begun, and there is still a long way to go.
