The development of smart grid has become a common choice for the power industry in the world to meet the challenges of the future, and is the development direction of the power system in the 21st century. As an important basic equipment for smart grid construction, smart meters are conducive to improving the operating efficiency of power companies, promoting energy-saving and emission reduction, and enhancing the stability of power systems. China needs to introduce a system and build a mechanism to give full play to the supporting role of smart meters in building a low-carbon society and developing a smart grid.
At present, there is no conclusion on the concept of smart electricity meters. The common view is that smart electricity meters are composed of measurement units, data processing units, etc. They have the functions of energy metering, information storage and processing, real-time monitoring, automatic control, and information exchange. New energy meter that promotes the visualization of electricity consumption and improves the energy management capabilities of users.
The development of foreign smart meters has a history of more than 30 years. In recent years, with the development of smart grids, major countries in Europe and the United States and Japan have introduced smart meter development plans and actively develop smart meter technology research and development and application.
It is reported that China plans to have 40 million smart meters installed in 2010. According to the statistics of the State Grid Corporation of China, according to the first three-year construction period, the amount of electricity that needs to be transformed and replaced in the smart grid construction is around 130 million. The State Grid Corporation of China has also issued a corporate standard, “Smart Energy Meter Functional Specificationâ€, to promote The standard development of smart meters.
As an important basic equipment for the construction of smart grids, smart meters have an important supporting role for the realization of informationization, automation, and interaction in power grids. They are linked to the development of smart grids, and their basic functions are to improve the operating efficiency of power companies and promote energy conservation and emission reduction. Power system stability.
Therefore, it is recommended to increase technological innovation. At present, the core technology of smart meters in China is too dependent on imports. In order to promote the sustainable development of China's smart grid, the first is to establish a smart electricity meter integration research mechanism, increase technological innovation, and overcome the chip, electrolytic capacitor, LCD screen, Two-way communication security and control, and other core technologies and high-end technologies; Second, in-depth analysis of the advantages and disadvantages of China's smart meter industry in the international market, delineation of key areas such as smart meter wide-area use of communication technology, smart meter close access communication technology, etc. The international standard roadmap actively strives for the right to speak in international standards.
Implement user-side energy management projects. The first is to increase the research and development of energy management systems, discuss the specifications of the user-side new appliances needed for the energy management system, and enrich the types of energy consumption services available to users; second, the government and power companies must create conditions and integrate the environment. Provide users with detailed information on energy supply and demand, and promote users from a simple "energy consumption subject" to "energy management subject" change, and actively choose the optimal energy consumption model.
Focus on promotion and popularization work. Taking the home user as a pilot target, the pilot project of smart meter application was conducted around the visualization of consumption power, the setting of peak-to-valley electricity price, and setting the time-of-use price with temperature changes, and the trial experience was summed up in a timely manner. According to the cost-benefit analysis of the pilots, the use of smart meters was gradually improved, and smart meters were gradually popularized.
Develop information exchange rules. Leading government departments and power companies cooperate to formulate rules for two-way exchange of power information, clarifying matters such as the use of information on the consumption of power users and the confidentiality of user information.
