Smart power security faces great challenges

Guide: with the construction of smart power in China, information security issues may face threats to information security in many fields, such as power dispatching automation, relay protection and safety devices, power plant control automation, substation automation, distribution automation, power load devices, power market transactions, power user information collection, intelligent power consumption and so on

the most serious power shortage in the past seven years has not completely passed, and the development of nuclear power is temporarily limited in the field of new energy vehicles and passenger cars, which makes renewable energy such as wind energy and solar energy attract people's attention again. With the large-scale consolidation of renewable energy with intermittent and volatile characteristics, such as wind power and solar energy, and the intensification of the energy crisis, the power system is facing unprecedented challenges. The complex interaction of power generation, transmission, transformation, distribution, power consumption and dispatching will make the problem of power security more prominent

at the same time, with the continuous emergence of new equipment and technologies in the fields of primary equipment intelligence and wireless communication, and gradually widely applied to the construction of power communication network, smart electricity has the characteristics of complex access environment, flexible and diverse access methods, a large number of smart access terminals, etc., which will increase the security risk of smart electricity. For example, many technologies being deployed to support smart electricity projects, such as smart meters and sensors, will increase the risk of electricity attack

in September 2010, a seismovirus named Stuxnet swept the global industry, infecting more than 45000 networks around the world, posing a huge threat and destruction to the power sector of all countries. Faced with the threat of making such traditional health products, the international community has begun to take action, not only to speed up the research and development and construction of smart electricity, but also to establish relevant departments to protect the safety of smart electricity. For example, the National Institute of standards and technology of the United States has specially established a professional research institution called the smart electricity collaborative network security working group to protect the security of smart electricity

also in China, the formulation of relevant smart electricity safety standards, technical research and industrial promotion are also actively underway. Guodian will invest more than 4trillion yuan in the next 10 years to promote the construction of strong smart electricity. Data shows that 15% of the total investment in smart electricity will be used for safety related construction. Obviously, in the future, China's smart electricity security market has great potential and broad development space

information security is an important basis for smart electricity security

it is understood that up to now, the United States, Europe, Japan and other countries and regions have carried out a lot of work in the concept, technical research and engineering practice of smart electricity. Among them, the definition of strong smart electricity in China is based on UHV as the backbone, the strong framework for the coordinated development of electricity at all levels, and supported by the communication information platform. It has the characteristics of informatization, automation and interaction, including all links of power generation, transmission, transformation, distribution, power consumption and dispatching of the power system, covering all voltage levels, and realizing the highly integrated integration of power flow, information flow and business flow

in this concept, communication information platform, informatization, automation, interaction, information flow and other words all show that ICT is inseparable from the development of electricity. Xu Zhen, technical consultant of Beijing Huadian ZhuoZhi information security technology evaluation center, said. With the construction of smart electricity in China, information security issues may face threats to information security in many fields, such as power dispatching automation, relay protection and safety devices, power plant control automation, substation automation, distribution automation, power load devices, power market when the power cord is at the midpoint of its journey, field trading, power user information collection, intelligent power consumption and so on. It can be said that information security has become an important foundation for the safe and stable operation of smart electricity and reliable power supply to the society, and is an important part of the production, operation and management of power enterprises. The Ministry of industry and information technology has also clearly stressed that we should attach great importance to the information security of smart electricity

baixiaoming, deputy general engineer of China Electric Power Research Institute and director of the strategic development research center, pointed out that in terms of telecommunications, China is similar to developed countries such as Europe and the United States, but China has obvious advantages in terms of power system monitoring. The information security of smart electricity is a threat to the infrastructure, which covers a wide range. The privacy protection technology of power users alone includes various technologies such as individual data and knowledge hiding technology. Gao Kunlun, deputy director of the Institute of information and communication of China Electric Power Research Institute, said

the construction of intelligent electrical safety system has been comprehensively accelerated

recently, the four UHV and intelligent electrical standards formulated by the State Grid Corporation of China were discussed at the first working group meeting of the Institute of electrical and Electronic Engineers (IEEE), which has just concluded. At this meeting, the above four standards were formally discussed and finally approved to establish a project working group. Once the technical system of the above standards is mature and internationally recognized, the above four standards will become international standards. This shows that China is on the same starting line with other countries in the world for the first time in the construction of smart electricity

the information security of smart electricity is a system engineering. A safe and stable electricity that can effectively resist internal and external attacks is the basic requirement of smart electricity, and the unified planning and deployment of security is the system goal of smart electricity. This includes the construction of special Trojan horse defense system, password technology, etc. a variety of information security means and products cooperate with each other and complement each other to maximize the use value, which is also the profound meaning of unified strong smart electricity

in this regard, Chengdu Westone Information Industry Co., Ltd. and Beijing Qiming Xingchen Information Security Technology Co., Ltd. are accelerating the research and development of security systems related to smart electricity

not long ago, the National Intelligent Power Research Institute funded by State Grid laid the foundation in the future science and Technology City, Changping District, Beijing. This marks a new page in the construction of strong and smart electricity in the country. As a research and development institution and high-tech enterprise of intelligent electrical equipment manufacturing technology, the Institute is of great strategic significance to support the development of strong intelligent electricity, enhance China's leading position in the global intelligent electricity field, and promote economic and social progress
