Just two days before the successful bid for the Olympics, the State Council approved the establishment of the Zhangjiakou Renewable Energy Demonstration Zone in Hebei Province, and clearly proposed to establish a leading international “low-carbon Olympic zone†to encourage enterprises to invest in local smart grid construction in a mixed ownership system. The long-standing smart grid construction is expected to enter a period of rapid development.
Smart grid gets attention
According to the “Development Plan for Renewable Energy Demonstration Zone of Zhangjiakou City of Hebei Province†jointly issued by the National Development and Reform Commission and the National Energy Administration (referred to as “Planningâ€), Zhangjiakou’s entire territory will be the core area, radiating Beijing-Tianjin-Hebei and other surrounding areas. We will focus on the reform of the electricity price system including power generation, electricity use, and power transmission and distribution, encourage enterprises to invest in the construction of smart grids in the form of mixed ownership, and improve the power trading mechanism of the demonstration areas across provinces and cities, to the Beijing-Tianjin-Hebei region. Conveying electricity.
In addition to the reform of the system and mechanism, the “smart grid construction†proposed in this plan is the most interesting. With the success of Beijing and Zhangjiakou's bid to host the Winter Olympics, the construction of smart grid will show a rapid growth trend.
There is currently no precise definition for smart grids. According to the US Department of Energy's "Grid 2030" report, the smart grid is a "fully automated power transmission network that monitors and controls each user and grid node, ensuring that all nodes in the entire transmission and distribution process from the plant to the end user The two-way flow of information and electrical energy"; and the definition given by the State Grid China Electric Power Research Institute is: based on the physical grid, modern advanced sensor measurement technology, communication technology, information technology, computer technology and control technology A new type of grid formed by the integration of physical grids. The outstanding feature of the smart grid is the refined integration of energy production and consumption.
Open up the scale of development
As far as the foundation of China's power grid is concerned, after years of rapid development, the architecture has become stable and mature, and has ample supply and distribution capacity. The construction of smart grids is largely the construction of distribution network systems, substation automation and power transportation, smart grid networks and smart meters.
Insiders pointed out that Zhangjiakou's construction of smart grid is simultaneously promoted by the coordinated development of Beijing-Tianjin-Hebei and Zhangjiakou's own development plan. Together with the concept of “low-carbon Olympic zoneâ€, the smart grid may use this to open a period of rapid development.
Promote renewable energy consumption
Cao Yu, chief researcher of Energy Internet at Cinda Securities R&D Center, told China Securities Journal that although China is currently facing structural oversupply, it does not affect grid investment from the current grid status. The smart grid is the strong supporting foundation for energy transformation. Through the smart grid, it can realize the effective consumption of renewable energy, the coordinated production of renewable energy and fossil energy, the intelligent interaction of energy production and consumption, and the new mode of energy consumption.
As the transmission line skeleton becomes more and more perfect, the focus of China's future smart grid construction will shift from the main transmission grid to the distribution network. In this context, the National Development and Reform Commission and the National Energy Administration issued the “Guiding Opinions on Promoting the Development of Smart Grids†in early July. The smart grid investment direction will shift from a strong smart grid based on UHV to a smart grid based on distribution network. More emphasis is on the user side of intelligence, the new form of power consumption, the interconnection of energy production and consumption, the distributed access of power sources and the effective consumption of renewable energy.
Insiders pointed out that along the above policy ideas, China's smart grid can achieve "horizontal multi-source complementarity, vertical source-network-load-storage coordination optimization", which will promote the utilization of renewable energy to the greatest extent and accelerate China's energy Structural Adjustment. At the same time, the construction and development of smart grid will also promote the application of Internet technologies such as “Big Data†and “Cloud Computing†in power systems, promote the development of energy storage, electric vehicles and distributed generation, and promote China's energy technology. And an overall upgrade in equipment level.
