Electrical energy is indispensable in the current society. However, the distribution from power generation to electric energy is an extremely complicated process, which not only consumes a lot of resources, but also has sufficient financial resources and advanced technical support. With the increase of electricity consumption in all aspects of society, more attention is paid to factors such as power quality, environmental protection, and cost. The existing grid mode has low efficiency and many unsafe factors, and it is difficult to meet the electricity demand of people in the new century. Based on the integrated high-speed two-way communication network, the smart grid can realize the safety, efficiency, stability, environmental protection and economy of the power grid by using various high-tech and advanced equipments. It is the future development trend. China's smart grid application time is short, the advantages have not been fully utilized, and the prospects are broad and further research is needed.

Smart grid automation

Automation can replace most manual operations, which increases productivity and reduces errors. Distribution automation and dispatch automation are more common in the past. Power distribution is an important part of power system. It is directly related to whether users can use electricity normally. Power distribution automation combines computer, modern control and network transmission technologies to make electric energy. The quality and power supply reliability are significantly improved, providing customers with better service. It also saves costs. The automatic isolation of automatic meter reading and line faults was realized in foreign countries. After the computer network technology was promoted, the integrated automation technology of distribution automation, power distribution management and user automation was gradually formed. China is relatively backward in this respect. It was only involved in distribution automation in the mid-to-late 1990s. There is still a gap between the current level and foreign developed countries.

With the core of computer, network communication and Far East technology, the mobilization automation has functions such as condition monitoring, risk assessment, load forecasting and automatic dispatching. It solves various problems that arise during early telephone command, and is conducive to improving the level of power grid operation and management. The power system is safe and stable. The technology has gone through three generations, and the fourth generation technology has also begun to be applied.

The automation of smart grid also has its drawbacks: the intelligent expert system on the dispatch side is still not perfect, and the unmanned operation is not fully realized, and there is no unified standard for the control and auxiliary decision-making system; the automation level of the plant is far lower than that of the developed countries; There are many kinds of systems, but there is a lack of communication between them, and coordination is poor; PID control technology is difficult to meet higher and higher requirements. Therefore, in the future, it is necessary to unify the standards of various control systems and carry out standardization construction. Actively study intelligent control methods to minimize manual operations; learn from abroad and learn from their successful experiences.

Informatization of smart grid

In the information society, information technology penetrates into all aspects, and grid informationization mainly involves two aspects: First, enterprise management, whether it is energy metering, information management, resource management or market research, all need to obtain sufficient needs in time. Information, while grid informationization achieves this; second, power production control, including energy management systems, data acquisition systems, and distribution management systems. In terms of communication hardware, quality performance has also been continuously improved. In the 1970s and 1980s, power line carriers and analog microwaves were mostly developed, but now they are developed into fiber, satellite, wireless, digital microwave, etc., and efficiency and safety performance are significantly improved, and coverage is even more. wide. After the 11th Five-Year Plan, China State Grid Corporation of China took SG186 information engineering as a key task, and many outstanding engineering projects have emerged, which is a major event in China's power information age. In fact, since the 1960s, China began the construction of information technology in the power industry. Due to the constraints of the time, it was mainly reflected in the use of computer systems to monitor substations and the operation status of power equipment. With the further development of computer and information technology, more and more high-tech has been applied to the power industry.

However, the process of electric power informatization construction is not smooth sailing. In this aspect, China's information integration is low, and information islands are prone to occur. There is a lack of communication between enterprises. The relevant standards are not uniform, too much investment in information collection and equipment, neglected information sorting, low utilization rate, and the enterprise production control system is often out of touch with the management system. This requires that the information standard in the industry must be unified as soon as possible, a sound power information platform should be established, and the platforms should be integrated and centralized. Make full use of the collected data information, carry out in-depth mining, and promote the combination of production control system and management information system.

Digitalization of smart grid

Information is intangible, and how to understand information in an easy-to-measure way is critical. Digitization converts information into digital data, making it easier for people to understand information more intuitively. At the same time, computer operation is done by numbers. Digitization is the foundation of computers. The digitization of power grids has appeared in foreign countries in the last century. At the beginning of this century, China introduced the concept of digital power systems, which can describe the structure and operation of power systems, as well as the economic benefits and personnel composition of enterprises. The digitization of power mainly involves the following two aspects: First, it is compatible with the enterprise information construction, using digital to represent the environment and management level of the enterprise; second, it is related to automation construction, that is, advanced application system based on digital simulation technology.

The current problems in the digital construction of power grids in China include: lack of information outside the system, such as wind power, illumination, etc., and related mathematical models are less; the advanced application system on the dispatch side is relatively mature, but the standard is not uniform, but the station side Digital construction can't keep up with the development speed of the dispatch side. In the future, in addition to the power system, it is necessary to consider the public service system, pay attention to geological and weather aspects, and construct corresponding mathematical models to better guide the digital construction. In addition, it is necessary to speed up the digitization process of the plant, and for the dispatch side, it should be developed in the direction of standardization and standardization.

Smart grid interaction

With the advancement of technology, there is a possibility of interaction between power generation and the power grid. The smart grid is created to achieve interaction between the grid and the power generation, between the grid and the user. Interaction is to increase the transparency of information, coordinate the complex relationship between the three, make management easier and easier, and maximize the benefits of the power industry. At present, there are also some problems. For example, the transparency of the electricity market is not high, which undermines the principle of fairness and justice in power competition. The power system has not yet truly realized the interactive process, and needs further improvement in the future; the installed capacity of renewable energy power generation is growing rapidly. However, the current research on the integration of renewable energy power generation is relatively lagging. In the future, we must continue to work hard, and we can learn from successful experiences from abroad.

Conclusion

With the increase in electricity consumption and the improvement of power quality and service requirements, the power grid industry needs further reform and innovation, and the use of modern high-tech to actively build a smart grid. Continuously improve the level of informatization and digitization, strengthen research on renewable energy power generation and its grid-connected, and thus improve the market competitiveness of China's power companies.
