The electricity meter and secondary equipment market first benefited from the increase in the "intelligence" word and further deepened the link with the electronic information industry, it will bring new opportunities for the development of the information industry. According to reports, the main features of the smart grid include self-healing, compatibility, interaction, optimization, integration, and access to various forms of power generation. Its core connotation is to realize the informatization, digitization, automation and interaction of the power grid. The realization of these features requires the support of electronic information technology.
Xiao Liye, director of the Institute of Electrical Engineering of the Chinese Academy of Sciences, said that the smart grid involves multiple technologies at the information and physical levels, including measurement technology, communications technology, chip technology, information platform technology, security technology, forecasting technology, advanced computing technology, and digital substation technology. , distributed power technologies, energy storage technologies and new material technologies, and many Other aspects. It is not difficult to find that these technologies are closely related to the electronic information industry, and the smart grid will undoubtedly bring enormous development opportunities to the latter. The related industries such as sensors, power equipment manufacturing, network communications, computers, chips, renewable energy, electric vehicles, and batteries will all be driven.
Power automation equipment is one of the most critical power grid equipments. Under the concept of smart grid, the difference between primary and secondary equipments is gradually decreasing, and domestic power equipment companies have thus obtained unprecedented opportunities.
According to Xuji Electric Chief Engineer and Zhou Jiquan, director of the XJ Group Smart Grid Research Center, the current demand for smart grid power equipment has been fully rolled out. For example, new standards for smart power plant products have been released. “In terms of the standard system, domestic companies and foreign companies are on the same starting line, and the development of smart grids will bring about the integration of primary and secondary equipment systems. This is a great opportunity for Chinese companies. "He said," We have developed a complete set of products for the new standard and will soon be ready for use. In fact, these products were very early in development, but with the changes in standards, the product has also been improved accordingly."
As far as the semiconductor industry is concerned, the intelligence of the power grid has also put forward higher requirements for the application of integrated circuits. Wang Zhihua, deputy director of the Institute of Microelectronics of Tsinghua University, said that the smart grid must be able to sense system overload and distribute power to prevent systems. Fault or minimize the impact of the fault. Smart grids use digital technologies, including the use of smart meters to detect power consumption, and the use of networked sensors and computer systems to control intermittently operated generators to produce electricity based on consumer demand, thereby increasing transmission efficiency. Smart grids allow distributed alternative energy sources to enter the grid, which also provides market opportunities for integrated circuits and semiconductor power devices. For example, in wind power generation, it is necessary to use a rectifying device to convert unstable AC power into DC power, and then use an inverter to convert AC power that can be accepted by the power grid into the power grid. The solar battery generates DC power, which also requires the conversion of the inverter before it can be connected to the grid. Whether it is a rectifier or an inverter, its core is a power semiconductor device. The measurement of distributed energy in the input power grid depends on integrated circuits.
It is understood that IT giants and semiconductor companies have already actively involved in the smart grid. Mao Li-ning, China regional manager for high-end enterprise customers of the Intel China Industry Cooperation and Solutions Division, said that Intel has established a joint laboratory with the State Grid Corporation of China to integrate high-performance computing and embedded technologies and use Intel architecture servers for grid modeling and simulation. To achieve network isolation and power station automation. Jin Yujie, marketing director of NXP’s Greater China Multimarket Products Division, stated that NXP’s diversified product line can meet the demand for various electronic components in the power system field. At present, their products are mainly used in power terminals and are negative. Control, set copying, and single-phase/three-phase electricity meters.
Experts said that from the power station to the power grid, to the substation, and then to the user, a smart grid composed of smart gateways will form a value chain. Observing the current development trend, smart meters and secondary equipment will become the earliest benefit of this value chain. In some countries in the United States and Europe, the smart meter configuration has been mentioned as the first step in development. It is reported that China also plans to have 40 million smart meters in the next year, and the State Grid has recently begun bidding for smart meters. Freescale, NXP Semiconductors and other semiconductor companies have introduced many new smart meter products and programs this year to strengthen the promotion of this market.
How smart is smart home terminal to change the life smart grid? Take smart homes, it uses power line broadband communication or optical fiber communication technology to configure smart terminals in the home to enable users to interact with the power grid, and further extend it through wireless communication technology to the antennae of water meters, electricity meters, gas meters, etc. for data capture. People can also use smart outlets to achieve electricity data collection and control of air conditioners, rice cookers and other electrical appliances; through wireless main network technology, a home application system integrating emergency assistance and smoke leakage detectors is established. Later, when people go out, if the puppy opens the refrigerator door, a text message will soon be received on the phone. If the thief touched the house, not to mention it.
The “battery replacement plan†is used for a comparison: the fuel truck travels 100 kilometers and consumes about 11 liters of fuel. According to the gasoline price of 6.6 yuan/liter, the fuel cost is about 70 yuan; the domestic pure electric vehicle travels about 100 kilometers and consumes about 15 Degree, electricity price 0.52 yuan / degree, fuel costs as long as 7.5 yuan. It can be seen that the cost of electric vehicles is about 1/10 of that of fuel vehicles.
State Grid is preparing to implement a “batter change plan†in Beijing to transform the taxi. A taxi drives into the station to ensure that a set of batteries can be replaced within 5 minutes. After this model is implemented, taxi drivers can increase their monthly income from 1,000 yuan to 2,000 yuan, while helping to save energy and reduce emissions, bringing "blue sky and white clouds."
Santana sees the high purchase price of electric vehicles in the future, which is due to the small volume of the market. However, the decline in the price of electric cars is a trend, just like Santana, which was produced by the Shanghai Automobile Factory. Twenty years ago, we saw a Santana in Yangzhou District and would cast a lot of envious eyes. At that time, Santana was priced from 200,000 to 300,000 yuan. After the scale of production, a Santana now sells for less than 100,000 yuan. If the issue of electric vehicle continued mileage along with the continuous development and development of the battery, can be effectively resolved, then it is not far off the market price cuts to a large area.
Making money with batteries in the future is not a dream. Wang Yimin stated in his report: In the future, electric vehicle batteries will become an energy storage device for smart grids. A person with a good economic mind can charge the car battery at low prices in the middle of the night. Once in peak hours, he can sell the stored energy. In the future, using batteries to make money is not a dream.
Compared with traditional fuel vehicles, the energy management system for electric vehicles is complex. In other words, when an electric car is charged and when it is discharged, it must involve energy management. Therefore, there is a very broad market for the construction of charging piles, charging stations, and its extension industries.
