Smart grids brewing huge market space

[Introduction: Smart Grid is a digital self-healing energy system that can optimize power supply, promote two-way communication between power grids, achieve end-user energy management, minimize power interruptions, and transmit power on-demand, bringing results to power plants and customers. The cost of commitment is reduced, reliability of power supply is increased, and carbon emissions are greatly reduced. Relevant data show that the future development of smart grids in the international market is broad and the development trend is strong. 】

Recently, a "2010 Phoenix New Energy, Smart Grid" Technical Seminar was held in Nanjing to explore energy development paths. Experts at the meeting believe that the development of new energy and smart grid has become a new industrial revolution, and research and development of new energy and smart grid technologies have important strategic significance.

A series of thrilling figures are stimulating people's nerves, and increasingly pressing energy pressures are constantly stirring up sensitive corporate business thinking. Although in 2009, the Chinese government successively proposed that China's non-fossil energy sources account for about 15% of the primary energy consumption ratio by 2020. In 2020, the GDP per unit of GDP will fall by 40% to 45% from 2005. However, 80% of China's electricity comes from coal. It is obviously difficult to achieve energy substitution in the short term. Smart grids are often considered as an important driving force for new energy development and an effective means to solve the current energy crisis.

In the 2010 Summer Davos Forum in Tianjin, the report “Accelerating the Success of the Smart Grid Pilot Project” was published, pointing out that the smart grid is a digital self-healing energy system that can optimize power supply, promote two-way communication between the grid, and realize end-user energy. Management, minimizing power outages, and transferring power on demand will result in lower costs for power plants and customers, improved reliability of power supply, and a significant reduction in carbon emissions.

Relevant data show that the future development of smart grids in the international market is broad and the development trend is strong.

China's "12th Five-Year Plan" energy policy has also clearly indicated that the smart grid must guarantee the stability and reliability of the grid and the efficiency of energy transfer. In response, Dr. Shuzhihua Shu, Director of the State Grid Protection Department, stated: "To achieve this goal, the smart grid must be characterized by informatization, automation, and interaction, including power generation, transmission, power generation, and distribution. All power, power, and dispatch links cover all voltage levels and achieve a highly integrated modern power grid that combines 'power flow, information flow, and service flow'."

"The power grid is developing from an earlier distributed network into an integrated energy system, achieving the above goals and automation is the key technology," said Roland Bent, Chairman of the New Energy Branch of the German Electrical Engineers Association and Senior Executive Vice President of the Phoenix Contact Group. It is reported that as the company's connection technology has completed the transition from the electrical signal interface to the optical signal interface, and extends the Ethernet communication to the site, it can easily realize the intelligent control and protection of the substation, as well as the remote monitoring of the local power grid.

What must be faced, however, is that the lack of core technologies is constraining China's energy development goals.

In its 2010 China Human Development Report “Towards a Sustainable Future with Low Carbon Economy and Society”, the United Nations Development Program pointed out that China’s goal of achieving a low-carbon economy in the future requires at least more than 60 backbone technical support. Of the more than 60 technologies, 42 are core technologies that China does not currently possess; the U.S. Department of Commerce’s “Guidelines for Clean Energy Exports” also pointed out that what China currently lacks is energy efficiency technology and energy management expertise.
