Talking about the advantages of green smart grid

Smart grid technology will significantly increase energy efficiency, thereby reducing greenhouse gas emissions and achieving sustainable development.

The smart grid mainly uses various existing information technologies to allow grid information to be analyzed. The traditional one-way manual meter reading at the customer end is changed to a bidirectional smart meter. Collecting instant and complete energy use information through smart meters to complete power automation dispatching and demand management.

For example, the current electricity meters are sent by the power company to read the meter, and the data on the traditional electricity meter only has one group, which is the electricity consumption of the current month. Smart meters will no longer require manual meter reading. With the use of short-range vertical transmission technologies such as zigBee , meter data from different regions can be transmitted to the base station and sent from the base station to the power company. In March 201O , ZigBee Alliance announced that it has reached an agreement with the Wi-Fi Alliance. The two parties will collaborate on the Wireless Home Area Network (HAN) for smart grid applications, covering everything from smart meters, thermostat devices and home entertainment devices. Cars and a series of smart home environments.

In addition, a variety of home appliances will also install sensors, connected to the smart meter, so that consumers can understand the power consumption of home appliances in the home, make electricity plans, which is " power automation supply scheduling. " The terminal equipment will also be changed. The smart grid platform combines the processes of power generation, power transformation, and power distribution to improve the operating efficiency of the power company and automatically manage the power demand. In addition to supplying electricity to civilians, if businesses or households have no power to self-produce, they can send back surplus electricity to the power company.

  This means that through the smart grid, the use of electrical energy can be brought close to the optimal level, reducing unnecessary losses.

Several advantages of smart grids are as follows:

1 . Accurate supply of energy Through information technology such as sensing, detection, remote control, etc., real-time tracking of demand, and intelligent analysis, control, so that more accurate supply of electricity, thereby reducing carbon emissions.

2 . Demand management smart grid platform can integrate demand management into electrical product design and system architecture, allowing users to respond to and communicate with grids and decentralized energy sources, and fundamentally solve problems through technological advancement.

3 . Power integration uses the backup concept of each system to provide mutual security. The current city's power system backup capacity and energy storage equipment can support each Other. Various forms of power generation such as wind power. Firepower, solar energy, and solar energy can together form an overall energy security. Under the deployment of smart grids, it ensures the security of electricity supply.

4 . The Innovation Platform Smart Grid creates an innovative technology environment for intelligent ionization and information appliances. The development of smart grids and the digital communication of power lines will be inevitable. According to the current technology, the 220V power grid can achieve a communication speed of 200M bandwidth, and the communication speed of most telephone lines is only 2M , which is far below the current level of the power line. Unless another fiber optic system is opened, the future potential of the power line will be further improved. . If the power line is used as a regional information exchange platform, networks, digital video phones, and digital televisions can all use this channel to achieve almost no cost information.

Judging from the progress of various countries, 2010 will be the year for the smart grid to take off. At present, the practice of all countries is to start with the replacement of the electricity meter. The United States, the United Kingdom, and Italy have already completed the replacement of some of the meters. By 2020 , the proportion of smart meters installed in the EU, the United States, and China will exceed 50 %.
