Can anyone explain the basic concept and basic structure of the smart grid?

This is a new concept, and there is no uniform standard yet.

According to the same scenario proposed by the United States, the European Union and China, it roughly includes the following aspects:

Smart grid is a new type of modern power grid that combines advanced sensing and measurement technology, information and communication technology, analysis and decision-making technology, automatic control technology and energy and power technology, and is highly integrated with power grid infrastructure.

However, due to the fact that the research and development of smart grid is still in its infancy, the national conditions and resource distribution of various countries are different, and the direction and focus of development are not the same, and there is no unified and clear definition of it in the world. According to the current research situation, the smart grid is to inject new technologies into the power grid, including advanced communication technology, computer technology, information technology, automatic control technology and power engineering technology, etc., so as to give the power grid a certain artificial intelligence, so that it has a strong adaptability, and becomes a fully automated power supply network.

Main characteristics: 1) Strong. In the event of major disturbances and failures in the power grid, the power supply capacity to users can still be maintained without large-scale power outages; It can still ensure the safe operation of the power grid under natural disasters, extreme weather conditions or external damage; It has the ability to ensure the security of power information.

2) Self-healing. It has real-time, first-class and continuous security assessment and analysis capabilities, strong early warning and preventive control capabilities, as well as automatic fault diagnosis, fault isolation and system self-recovery capabilities. - This one is actually closely related to the previous one.

3) Compatible. Support the orderly and reasonable access of renewable energy, adapt to the access of distributed power sources and microgrids, and realize interaction and efficient interaction with users, meet the diversified power needs of users and provide value-added services to users. ——Linked to the limited proportion of new energy access and the demand for energy conservation and emission reduction, it has been vigorously advocated and supported.

4) Economy. Support the effective operation of the electricity market and the effective development of electricity trading, realize the optimal allocation of resources, reduce power grid losses, and improve energy efficiency.

5) Integration. Realize the high integration and sharing of power grid information, adopt a unified platform and model, and achieve standardization, standardization and lean management.

6) Optimization. Optimize the utilization of assets and reduce investment costs and operation and maintenance costs.

It can be said that smart grid is a big concept, power supply reliability, energy utilization, energy quality, grid automation, etc. all belong to the category of intelligent grid; The digital power system is only a means and basis for the realization of the smart grid, and the digital transformation of the power grid seems to be necessary to realize the smart grid.

The difference between smart grid and digital power system is that the digital power system is only a part of the informatization and automation in the smart grid, which is far less extensive than the smart grid, and the digital power system is only reflected in the digitization of information collection, transmission and control.

The connotation of smart grid is mainly reflected in the following five aspects:

1.Strong and reliable, strong grid, strong conveying capacity, safe and reliable;

2.Cost-effective, improve the efficiency of power grid operation and transmission, reduce operating costs, and promote efficient use of energy;

3.clean and environmental protection, development and utilization of renewable energy;

4.Transparent and open, transparent and open implementation platform;

5.friendly interaction;

Its basic characteristics are informatization, automation and interaction;

According to my personal understanding: smart grid, is a power supply network, specially used to overhaul the line and power supply, for example: your line is broken, people can not check each line is the first problem, this smart grid can accurately find the first problem.

Digital power system: It is a power supply system, which is used for distribution work, especially when it comes to peak power consumption, and if you want to stagger peak power consumption, he will deal with this.

The above answers are personal understanding, if you want to know exactly what it means, please refer to the relevant department information.

The connotation and concept of smart grid in different countries are different, in China, its main realization is 1Strong and reliable, strong grid, strong conveying capacity, safe and reliable;

2.Cost-effective, improve the efficiency of power grid operation and transmission, reduce operating costs, and promote efficient use of energy;

3.clean and environmental protection, development and utilization of renewable energy;

4.Transparent and open, transparent and open implementation platform;

5.friendly interaction;

The basic characteristics are informatization, automation and interaction;

As a digital power system, it is only a part of the informatization and automation in the smart grid, which is far less extensive than the smart grid.

It is only reflected in the digitization of information collection, transmission and control.
