As people's demand for energy increases, energy and the environment are faced with severe challenges, and the requirements for green energy are increasingly urgent. The key to green energy depends on intelligence and environmental management, reducing waste and targeting. As a development direction of the modern energy society, the smart grid plays a decisive role.
The state focuses on the development of smart grid projects
According to estimates by authoritative data agencies, the smart grid technology market will grow from 33 billion U.S. dollars in 2012 to 73 billion U.S. dollars in 2020. In eight years, the market has reached 494 billion U.S. dollars. During the "12th Five-Year Plan" period, the State Grid will invest 500 billion yuan to build a world-class strong smart grid. The purpose of the smart grid is to build highly efficient energy distribution, energy saving, and power management. Smart homes and smart power are important components of smart grids. In recent years, indoor display terminals (IHD) and home power management have also become electric power. The company's important research topics.
The country is making great efforts to promote the work of smart grids. The front-end smart meters are installed quickly, but back-end data integration is still far behind. In addition, with the development of smart grids, the intelligent degree of power dispatching systems is increasingly demanding. Since the "Twelfth Five-Year Plan" period, the State Grid Corporation of China has proposed an integrated dispatching and operation system, which requires the "overall fusion" of the operation monitoring, troubleshooting, dispatching and commanding of information and communication, which imposes more stringent requirements on power communication technology.
Smart Grid Promotes Smart Home Applications
The smart grid is undoubtedly one of the mainstream directions for the development of the overall power system in the future. At the same time, its construction and promotion will promote the development of smart home technologies and will facilitate the popularization of smart home applications.
It is understood that the United States has emerged a smart grid city in 2008 and built the first large-scale smart grid in Florida in 2013; Germany’s “E-Energy†program has a total investment of 140 million euros, from 2009 to 2012. Smart grid demonstration experiments are conducted in 6 locations; Japan plans to spread the smart grid in 2030; China National Grid Corporation plans to build a strong smart grid with informatization, automation, and interactive features in 2015. In the near future, this trend will completely change our living habits, and smarter, greener and smarter lifestyles will soon begin.

On February 14, 2012, China officially issued the “12th Five-Year Plan for Development of the Internet of Thingsâ€. The “Planning†delineated nine major applications for key development, including industrial smart industries, smart agriculture, smart logistics, and intelligent transportation. Smart and environmental protection, as well as smart grids, smart security, smart medical care and smart homes.
Nowadays, the rapid development of smart grids has promoted the construction of smart communities/buildings in various regions. The district/buildings are the most basic unit of urban crowds and the terminal of smart electricity. Apart from satisfying basic life functions, the smart community also needs to consider five elements: safety, health, energy saving, convenience, and comfort. With the popularization of smart meters and power collection systems, it will make it easier for residents to have a life-related experience at home. .
Smart grid can not only ensure the safety of users' electricity, but also enable the community and families to have many security functions such as automatic alarm, video surveillance, entrance and exit management, remote defense and disarm, and so on, which greatly enhances the security of the family, for the community and the family. Security quality and upgrade of grades will bring great benefits. The smart grid is also the primary prerequisite for realizing home intelligence. Therefore, China should vigorously develop and promote the smart grid so that more ordinary citizens can enjoy “smart life†as soon as possible.
Smart grid supports smart city construction
“The smart grid is the carrier of urban wisdom development, supports the operation of all aspects of smart cities, and supports the construction of smart cities.†Liu Jianming, the State Grid Ministry of Science and Technology, stated at the 3rd China Smart Grid Construction and International Forum. Liu Jianming said that smart grids are the city’s facilities for access to clean energy, energy conservation and emission reduction, and information infrastructure, and are also one of the foundations for the development of urban related industries.
Liu Jianming pointed out at the meeting that the main contributions of smart grids to smart cities are mainly reflected in four aspects.
First, the economy. The smart grid accelerates the energy-saving transformation of existing industries, creates new industries, and promotes economic structural transformation. Second, energy. In the development of smart grids, the use of technologies such as "substituting coal for electricity and electricity for electricity" has increased the proportion of electricity in terminal energy consumption. Third, information. Smart grid construction can not only enhance the level of urban informatization, but also promote “triple play†and build a public network platform in cities. Fourth, environmental protection. The establishment of a smart grid is conducive to protecting the environment, improving energy efficiency, reducing energy consumption, and reducing carbon emissions.
Liu Jianming emphasized that the smart grid is an important basis for the subjective development of urban intelligence and an objectively needed energy carrier. The smart grid can not only ensure the safe and reliable use of electricity in cities, promote the green development of cities, build up the urban nervous system, enhance the development of related industries in cities, but also have an important supporting role in the development of smart cities in the construction of urban service platforms.
About smart grid
The smart power grid (smartpower grids) is the intelligentization of power grids, also known as “grid 2.0,†which is based on an integrated, high-speed two-way communications network, advanced sensing and measurement technologies, and advanced equipment technologies. Advanced control methods and application of advanced decision support system technology to achieve the goal of reliable, safe, economical, efficient, environmentally friendly and safe use of the power grid. Its main features include self-healing, motivating and including users, resisting attacks, and providing satisfaction. In the 21st century, the power quality required by users, access to various forms of power generation, and the start-up of the electricity market, as well as the optimization and efficient operation of assets.
