Vigorously develop smart grid based on Internet of Things technology, we need to enjoy life
It has become a consensus in the industry to build a power grid that is efficient, intelligent, and fully capable of ensuring the integration of renewable power energy into the network and ensuring the stability of solar and wind power generation. The industry generally believes that the construction of smart grid has spanned the power sector, involving manufacturing, information, electronics and other fields, requiring coordination and support from government finance and industrial policies. At the same time, in the field of power distribution, large-scale power generation will be adopted in the future. The combination of access and distributed generation access, and the construction of distributed generation also requires government support.
To this end, the Chinese government began to promote the integration of power networks and the Internet of Things, namely the smart grid. The industry standard for smart grids has not yet been formed. At present, the content of its unified recognition is: through the related Internet of Things technology to achieve interconnection and interconnection of power grid equipment, to create a modern power system. The core connotation of the smart grid is to realize the informationization, digitization and intelligence of the power grid. In the current phase of integration of power network and Internet of Things, China mainly implements the adjustment and upgrading of six major links: power facility monitoring, intelligent substation, distribution network automation, intelligent power consumption, intelligent dispatching, and remote meter reading.
According to the analysis of the status quo of China's power system and power grid development, China's development of smart grids needs to focus on the following aspects:
1. Smart grid construction and power market reform should be carried out simultaneously. The power market has not yet formed and the grid supervision system is still immature. The development of smart grids is to better save energy and reduce emissions, and this goal is to increase residents. The use of electricity to stimulate the marketization of electricity prices. The current administrative control price has created tremendous resistance to this goal.
2. Further strengthen the intelligent construction of the distribution grid and improve the quality of electricity. The development of distributed energy technologies is still an important part of future development, which can quickly shorten the distance from developed countries.
3. The development and application of smart grids will face the requirements of information security, and the reliance on information and communication infrastructure will continue to increase. This is first to ensure the security of the power communication network, and secondly to ensure the privacy of information and data, to ensure that user information is not leaked.
4. Improve the unified standards for R&D energy, improve the corresponding management methods and administrative provisions, and continue to demonstrate the use of distributed energy in China's power system, and provide cutting-edge recommendations for the construction and development of China's national power grid. Promote the development of renewable energy sources, such as China's northwest, northeast and North China.
5. The use of smart grid design in many departments and the national population requires the guidance, organization and construction of the government and the equal participation of all parties.
The comprehensive construction of smart grids in China will lead to a comprehensive transformation of power equipment. Building a unified smart grid requires a large number of transformers, switches and other equipment, which is expected to account for about 40% of the total investment in the grid. Domestic and foreign power equipment manufacturers have adjusted their research and development direction and tackled smart equipment. Transformer, high-voltage switches, reactors and other primary equipment industries have been studying the possibility of combining intelligence with sensors to achieve intelligence. Secondary equipment industries such as relay protection devices and automation control equipment have cooperated with equipment manufacturers to explore ways to integrate primary and secondary equipment.
The smart grid can maximize the power generation of new energy sources, and ensure the safe operation and dispatch of the grid after access. The construction of ultra-high voltage transmission lines of smart grid can minimize the loss of long-distance power transmission; intelligent dispatching will distribute power more reasonably and greatly improve the efficiency of electricity consumption. The completion of the smart grid will greatly enhance the efficiency of energy use, reduce dependence on energy such as coal and natural gas, and promote the use of renewable energy such as solar energy and wind energy.
In terms of civil use, the rapid development of smart grids in the past two years has promoted the construction of smart communities/buildings in various places. The community/building is the most basic unit for gathering people in the city, and it is also the most terminal for smart electricity. In addition to meeting the basic life functions, the intelligent community should consider the five elements of safety, health, energy saving, convenience and comfort. With the popularization of smart meters and power collection systems, it can make the life experience related to electricity in residents more convenient. .
The smart grid can not only ensure the safety of users' electricity, but also enable the community and home to have many security functions such as automatic alarm, video surveillance, entrance and exit management, remote fortification and disarming, etc., which greatly enhance the safety of the family. The improvement of security quality and grade 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 the "smart life" as soon as possible.
