Technology News丨Entering a new era of electricity consumption: "Grid 2.0"

Electricity is one of the most familiar and inseparable forms of energy in our lives. Many things in our daily lives use and consume electricity, and the normal operation of the entire city also requires the support of the power system .

Smart grid is the intelligence of power grid, also known as " grid 2.0 ". It is based on an integrated, high-speed two-way communication network . Through the application of advanced sensing and measurement technology, equipment technology, control methods and decision support systems, it achieves the goals of reliable, safe, economical, efficient, environmentally friendly and safe use of power grid .

A.

It has a strong grid infrastructure and technical support system , which can adapt to the access of large-scale clean energy and renewable energy;

B.

Information technology, sensor technology, and automatic control technology are organically integrated with the power grid infrastructure to obtain panoramic information of the power grid and promptly discover and foresee possible failures;

C.

The widespread application of technologies such as distribution automation makes power grid operation control more flexible and economical ;

D.

The comprehensive application of communication, information and modern management technology will greatly improve the efficiency of power equipment, reduce power loss, and make the power grid operation more economical and efficient;

AND.

Realize high-level information integration, sharing and utilization, and provide corresponding auxiliary decision support, control implementation plan and response plan for operation management ;

F.

By establishing a two-way interactive service model, users can understand the power supply capacity, power quality, electricity price and power outage information in real time and arrange the use of electrical appliances reasonably.

Nowadays, with the gradual development and growth of various new energy sources such as wind power generation and solar power generation , new challenges have been brought to the development of the power system.

The power system not only has to face the unpredictable electricity demand on the user side , but also the complex and changeable energy supply side.

In the traditional power system , electricity mainly depends on thermal power and hydropower, which have relatively stable power generation and are relatively easy to control.

However, new energy sources such as wind and solar energy are easily affected by weather, and their power generation is not stable enough, which increases the difficulty of controlling the power grid.

Smart grid transforms the dynamic regulation mode of traditional grid into an advance prediction mode:

The smart grid system will install smart sensors on each user's node and upload the electricity consumption information to the cloud platform, analyze and deduce the collected big data, and finally accurately determine the future electricity consumption trend to avoid waste caused by power generation exceeding power consumption.

As a new grid architecture proposed to adapt to the modern energy model, smart grid has the characteristics of reasonable structure, safe operation, efficient and flexible control .

Smart grids have the characteristics of reasonable structure, safe operation, efficient and flexible control . From individuals to high-energy-consuming industries, smart grids can help users easily and accurately grasp the power consumption of each home appliance, equipment, and process, and can timely perform energy-saving control on links with high power consumption .

Electricity is the lifeblood of modern society and an indispensable energy source for industry and life. Scientists believe that in the near future, "Grid 2.0" will make electricity use more efficient, not wasting every kilowatt-hour of electricity, and help us enter the era of green economy .
