At the 2014 China Future Energy Forum to be held on November 14, Zhang Wei, vice president of the State Grid Energy Research Institute, said: "Now, the State Grid invests 300 billion yuan in smart grid every year." Many experts pointed out at the meeting that the development of smart grid can more effectively access the new energy such as scenery and provide a more reliable basis for the planning, construction and service of power grid.
Smart grid market has a bright future
Shi Dinghuan, a counselor of the State Council, said in his speech that the smart grid is an important technological means to promote renewable energy. It can closely integrate informationization and energy cleanup, greening and low carbonization. At present, the energy supply end comes from different energy systems such as wind power, solar energy and hydropower, and the power generation end and the power supply end are unstable. The smart grid eventually has to reach the ends that will be unstable, effectively connecting through information systems and ensuring an effective balance of the entire system.
Zhang Wei introduced from the power generation point of view, the smart grid can be a good solution to intermittent large-scale access to power grid problems; from the user side, with the user to achieve a good two-way communication and interaction, especially to solve the electric car Access to new energy-consuming facilities and the problem of electricity consumption; at the same time, it can solve various complicated interferences in the operation of power grids and maintain the stable operation of the system.
National Grid had previously said that during the "12th Five-Year Plan" period, the national grid is expected to invest about 1.6 trillion yuan in the construction of a strong smart grid. The smart grid "Twelve-Five" special plan proposed to establish a more complete smart grid industry chain, basically built with information, automation , interactive features of the smart grid. Build 20-30 smart grid technology demonstration projects, build 5-10 smart grid demonstration cities.
For the future construction of smart grid, Zhang Wei suggested that the network to be strong, to connect the grid, rational planning, including networking with neighboring countries; highly intelligent, electric cars can plug and play; to a wide range of interconnects, including the geographical scope , But also coordination with other energy systems. "From State Grid Corporation, we hope that the development of the power grid will be integrated with the development of the Internet. Through the development of information technology, including the adoption of mobile terminals, we will intensify the interaction with users."
Promote the integration of new energy sources
With the rapid development of new energy sources, a number of participating experts said that the development of smart grids can access new energy sources such as landscapes more effectively and solve the current problem of discarding abandoned and discarding waste water.
In recent years, China's clean energy is developing rapidly. As of the end of September 2014, the cumulative installed capacity of clean energy in the country exceeded 400 million kilowatts, accounting for more than 30% of total installed capacity. Among them, the cumulative installed capacity of hydropower over 290 million kilowatts, wind power reached 84.97 million kilowatts, solar photovoltaic power generation more than 20 million kilowatts. The mismatch between power and electricity markets has also created the problem of abandoning the wind and discarding waste water.
Bi Yaoxiong, deputy general manager of Three Gorges Group said that the smart grid should provide a good foundation for the development of wind power and photovoltaic power generation access to the power grid to create conditions for the centralized power generation and distributed generation into the power grid to maximize the power grid to achieve Rational allocation of power science and economic dispatch.
Bi Ya Xiong introduced China's wind and solar energy resources are relatively concentrated, mainly in the remote areas of the grid should be developed large-capacity, long-distance renewable energy transmission, combined with water, fire, water, water and light transmission and other methods, and greatly enhance the storage Technology research and application. Based on the advantages of large-scale hydropower development, the Three Gorges Project is actively exploring new modes of hydropower, wind power, photovoltaic and other clean energy complementation, bundling development and delivery along the Yangtze River. At the same time, the smart grid should allow power consumers to participate in the optimal operation of the power grid. Relying on energy storage and micro grid systems, smart grids should be built to achieve widespread acceptance of distributed power plants and promote better utilization of energy and energy saving Consumption (Our reporter Ouyang Chunxiang)
