The development plan of the Smart Grid of the State Grid Corporation of China mainly promotes the development of the smart grid from two levels of technology and equipment. According to the research on the smart grid, the smart grid construction needs to start from the three levels of infrastructure, interface communication and application, and it needs to establish a sound Smart grid standards, the introduction of relevant policies. Corresponding to the smart grid architecture, the equipment level is mainly the infrastructure layer and the interface communication layer, and the technical level is mainly the application layer, smart grid standards and policies.
As a revolutionary new technology application for power grid development, smart grids will generate many investment opportunities, and at the same time, a large number of new applications and profit models will emerge. Below we analyze smart grid investment opportunities from three levels.
Infrastructure investment is imminent, and investment opportunities are huge. However, the barriers to entry are high, and many pre-accumulation infrastructure layers are required to build smart grids. The construction of domestic smart grids will gradually start with this. The smart grid infrastructure is basically similar to the existing power grid. It mainly includes primary and secondary equipment, but it needs to upgrade existing equipment and install sensors to meet the data transmission and equipment interaction. At the same time, smart grids need to address large-scale, fast, low-loss, and secure storage of energy.
At present, the domestic grid companies have announced a huge grid investment plan, of which the State Grid Corporation of China plans to invest 260 billion yuan in 2009, South China Network plans to invest 113.4 billion yuan, and China plans to invest 373.4 billion yuan in grid power. It is expected that 32% will be used for equipment procurement, totaling RMB 119.5 billion. Transformer products as power transmission main equipment will face strong market demand.
On the user side, the scale of investment is gradually expanding. Starting from 2009, the State Grid Corporation plans to invest nearly 80 billion yuan in 3-5 years to establish a power consumption information collection system for 27 provincial network companies under the system. The procurement fund for electricity automation management systems and data acquisition terminals is about 23 billion yuan, and the procurement funds for the carrier list are about 27 billion yuan. With the advancement of smart grid construction, the demand for smart meters will increase significantly.
Energy storage is a very important demand for smart grids, but at present it is still technically imperfect. There is still a shortage of energy storage in both quantity and quality, and technology leadership will be the main barrier in this area.
The long period of construction of interface communication and relatively high technical requirements requires patient waiting for market opportunities. The most important feature of smart grids is interactivity. The interaction here consists of two levels: one is the interaction between grid devices and the other is between grids and users. of interaction. The premise of the interaction requires that the grid equipment and meters be IP-enabled, that each device has its own IP, and that various interactions can be achieved through the sensors and that the grid will be more intelligent. The main investment opportunities in the interface communication layer are communication networks and sensor-based communication planning and protocol conversion equipment. In addition to a mature optical network, carrier communication is a convenient transmission method and will be used in depth in remote areas.
Experts predict that in order to transform the smart grid, the transformation of the network communication infrastructure will cost nearly a trillion yuan, including computers, sensors, and network systems. This is a huge new market for IT and network companies. For the time being, there are already a number of electrical, IT, telecommunications, and internet giants involved in this area with various channels.
The application layer has a large investment opportunity in the later stage of the smart grid construction, but it should be in the cultivation period at present, and it needs to invest sufficient force in the research of the new application model.
The application layer as the top layer of the smart grid determines the value of the smart grid. It is believed that there are several development directions such as smart dispatch, grid self-healing, transaction integration, and household intelligent power utilization. These applications will result in a series of new applications in the power grid industry and will inevitably occur in the future as smart grid construction progresses. Many new application models and profit models.
Intelligent scheduling is based on understanding the information of the entire network, using information technology to adopt a reasonable operation mode to achieve scientific, rational, and energy-saving scheduling. It is necessary to study how to optimize the arrangement of operating modes, optimize the distribution of system currents and line currents, reduce reactive power traversing, rationally arrange equipment maintenance cycles, increase the economic operation of transformers and reactive power equipment, rationally use UHV transmission power, and strive to reduce voltages Hierarchical network loss; how to rationalize new energy sources such as wind power and photovoltaics, and make more effective use of clean energy on the basis of ensuring the safety of power grids.
The self-healing of power grids is based on the information exchange between power grid equipment and the use of real-time control equipment of sensors and automation facilities to predict and detect faults in the power system and react accordingly, automatically avoiding blackouts and deterioration of power quality.
The integration of transactions will become a new application in the environment of power system reform, and the integration of power generation and real-time transactions between users of similar securities transactions will be possible. Trading middlemen may be a new grid operation role.
Smart home electricity is based on the help of smart meters, according to the user's settings, combined with power grid real-time electricity price information, can achieve automatic control of household appliances, rational use of electricity, reduce peak power demand, reduce user electricity spending.
