Smart grid has become a new growth point for the informatization of the power industry

In 2009 , it was a period of discomfort for the power industry. The financial crisis, the acceptance of the “ Eleventh Five-Year Plan” project, and the smart grid all contained challenges and opportunities for power companies. The impact of the international financial crisis in 2009 on China’s economy gradually shifted from a virtual economy to a real economy. For the power industry, the most important performance is the decline in the demand for electricity. In the first half of 2009 , electricity demand decreased by approximately 3% compared with the same period in 2008. Coupled with the unfavorable factors of coal-fired electricity linkage to power companies, the efficiency of power companies in the first half of 2009 declined, until the second half of the year. Eased.

The “ Eleventh Five-Year Plan” project entered the final stage, and the IT industry investment in the power industry increased at the bottom.

According to the “ Eleventh Five-Year ” informatization plan of the power industry, most of the projects will be initially completed by the end of 2009 . In 2009 , some large-scale IT projects in the power industry began to enter the acceptance phase, while other projects accelerated their pace to enter the critical period of implementation. CCW Research " 2010 China's Power Industry Information Construction and IT Application Trends Report" shows that in 2009 the IT investment scale of the power industry slowed compared to 2008 , compared to the power grid companies. The growth rate of investment in information technology is faster than that of power generation companies. In 2010 , the growth rate of investment in information technology in the power industry will bottom out.

In 2009 , the “SG186 Project ” of the State Grid was nearing completion. Acceptance of the “SG186 Project ” of the State Grid was a major event in the power industry in 2009. Shanghai Huadong Company, a subsidiary of the State Grid, took the lead in passing acceptance. After the implementation of the SG186 project, the State Grid Corporation's system information level has been greatly improved, the overall image has been continuously improved, and informationization has achieved a leapfrog development from a department level to a corporate group level, achieving vertical integration and horizontal integration, and in the production and operation management of the company. Played an important role; integrated enterprise group-level information system has become the necessary support and strong support for the daily operation of the company, which has effectively promoted the continuous promotion of the company's “ four modernizations ” and laid a solid foundation for the scientific development of the company and the power grid. Deepening group operations provides a powerful tool.

The smart grid has a profound impact on the upgrading of the power industry.

In recent years, with the rapid development of China's economy, the demand for electricity in China's society and economy has also shown a rapid growth. If blindly expanding the scale of the power grid does not solve the problem of large power loss in the traditional power grid, and it is difficult to dynamically regulate power usage, it will be difficult for the power grid system to adapt to the requirements of economic development. In May 2009 , the State Grid Corporation of China announced for the first time its “ Smart Grid Project ” . The State Grid Corporation of China is building a strong grid with coordinated development of UHV power grids as backbone grids and grids of all levels, with information, digitalization and automation. , Interactive four characteristics as the independent innovation, leading international strong smart grid.

Smart grid primarily by the sensor between the user terminal to form a network connection for real time interaction between the user and the power company, so that real time (real-time), high speed read data (high-speed), two-way (two The effect of -way ) is to improve the overall efficiency of the power grid as a whole. Simply put, a smart grid connects various devices and assets through sensors to form a customer service bus, which integrates analysis of information, so as to reduce costs, improve efficiency, and increase the reliability of the entire power grid. And management are optimized. Smart grids use the intelligence of technology to realize the marketization of the power industry, thereby greatly alleviating power shortages and power outages. On the surface, the construction of a smart grid requires a lot of financial and technological investment, and it may not be economically beneficial to society. However, in the long run, the profits generated by smart grids are enormous.

The smart grid will become a new growth point for pulling the informationization needs of the power industry.

The essence of the smart grid is energy substitution and compatible utilization. It needs to integrate the data in the system and optimize the operation and management of the grid based on the creation of an open system and the establishment of a shared information model. To realize the ubiquitous “ smart ” features in the entire power grid, collaboration between the power and IT industries is inevitable. In the National Grid smart grid plan, about 60-80% of the investment will be used for non-traditional projects such as remote control and interactive intelligence. The demand for IT support from the power grid is unprecedented, and the smart grid will become a new growth point that will drive the information industry demand in the power industry.

The start-up of the “ Strong Smart Grid ” plan of the State Grid Corporation will drive major changes in the operation and management of the grid, customer service, and social energy utilization patterns. As the breakthrough of the “ four modernizations ” feature of the smart grid, informationization has become an important issue. The important characteristics of informationization under the smart grid, its development trend and construction direction will become the common concerns of power grid companies and the IT industry. In the smart grid construction environment, enterprise information will penetrate into every link of the grid business value chain. The combination of management informatization and automation will be closer. Both technology leadership and business will be driven equally. Informatization and business innovation will be deeply integrated.

The State Grid Corporation of China adheres to the smart grid in three steps: First, the pilot phase of the pilot project from 2009 to 2010 , focusing on the development of a strong smart grid development plan, formulating technical and management standards, and conducting key technology research and development, equipment development and pilot work in all aspects. Second, from 2011 to 2015 , it will be a comprehensive construction phase, accelerate the construction of the “ Three Chinas ” UHV synchronous grid in North China, East China and Central China, initially form a smart grid operation control and interactive service system, and achieve major breakthroughs and extensive application of key technologies and equipment; Third, from 2016 to 2020 , it is to lead the promotion phase and build a unified and strong smart grid. The technology and equipment have reached the international advanced level. It is estimated that the total investment of the smart grid will be close to 4 trillion yuan by 2020 . Specifically, the investment in 2009 and 2010 is about 550 billion yuan, of which the UHV power grid investment is 83.0 billion yuan; the total construction investment is about 2 trillion yuan, of which the UHV power grid investment is 300 billion yuan; and the basic construction phase is 1.7 trillion yuan. Which UHV investment 250 billion yuan. If IT 's investment accounts for five-thousandths of them, then this will be a very large number. It can be expected that the smart grid will drive the investment demand for information technology in the entire power industry in the next few years.
