The US National Fund Committee first proposed the concept of information physical integration system (CPS). In the following years, CPS became the key research direction and international academic research hotspot of the US government in the field of information technology. CPS is based on the perception of the physical world, deep integration of computing, communication and control capabilities. Through the coordination of the information space virtual network and the physical space entity network, the physical system has higher flexibility, autonomy, reliability and economy. Sex and safety. The vision of CPS is to become the foundation of all large-scale industrial systems. For example, in the “Industry 4.0†strategy proposed by Germany, CPS is a key basic technology aimed at realizing the intelligentization of industrial production systems and processes. In the future, large-scale infrastructure and important industries such as electricity, energy, transportation, manufacturing, and logistics will become CPS.
Today's power grid has entered an era of intelligence. The smart grid widely uses wide-area sensing and measurement, high-speed information communication networks, advanced computing and flexible control technologies to realize informationization, automation and interaction in the six links of power generation, transmission, substation, power distribution, power consumption and dispatching. . In the smart grid, more and more power equipment adopts the embedded system structure. A large number of electrical equipment, data acquisition equipment and computing equipment are interconnected through two physical networks: the power grid and the communication network. To a certain extent, they already have the basics of CPS. feature. With the construction of power grid automation system, large-capacity transmission network and ubiquitous sensor network, and deep integration with the Internet and energy network, the smart grid will continue to evolve into a complex network with wide-area coordination and autonomous behavior, thus forming grid information physics. Fusion System (GCPS). GCPS adds or expands new capabilities through deep integration and real-time interaction of grid information space with physical space to monitor or control grid physical devices or systems in a safe, reliable, efficient, and real-time manner.
As a new technical concept, GCPS provides new ideas and ways to achieve the goal of intelligent grid. The virtual and physical integration of grid information space and physical space will become a regular system form, which can further improve grid operation from the following aspects. Efficiency and service value.
GCPS will significantly improve the information awareness, integration, sharing and collaboration capabilities of the grid. China's power grid is now in a period of rapid development. The grid structure and operation mode are becoming more and more complex, and the system is facing many risk factors. In addition to the existing information collection and transmission systems such as dispatching, production and marketing, GCPS can also realize the extensive collection and sharing of multiple physical quantities or data through intelligent power equipment, industrial-grade sensor networks, smart homes, etc. The data barrier between the two makes it possible to achieve synergy across time, space, and physical environment, achieving deep understanding of the state of the grid and efficient use of data resources. Under the system architecture of GCPS, various types of information can be comprehensively and fully integrated for fast and accurate fault diagnosis, thereby reducing power interruption time and enhancing power supply reliability. In addition, GCPS will also be able to achieve multiple cross-industry collaborative controls with other social networks, such as transportation networks.
GCPS will significantly improve the self-organization and self-adaptation capabilities of the grid. The power grid is a complex information physics infrastructure. Under the smart grid environment, the information carried by the information communication network is increasingly complex and arduous, and has become an inseparable part of the grid production operation and monitoring control. GCPS will support the synergy between global optimization and local control through the integration of information and network. In addition, GCPS has an adaptive function, which has a relatively accurate grasp of information such as load control, device characteristics and user preferences. It can realize local control of physical equipment and online adjustment of parameters of control center, and automatically eliminate various system faults ( Including physical system failures and information communication system failures), the ability to ensure the normal operation of the system.
GCPS will enable the grid to have the capability of large-scale distributed real-time computing. The characteristics of the power grid are that energy generation and consumption are instantaneously balanced. Any critical dynamic changes of the power grid place high demands on the reliability and real-time control of the power grid. GCPS will integrate the continuous model of the physical grid with the discrete model of the computer, break through the constraints of the traditional centralized computing platform, and integrate the information embedded in the physical device with the central monitoring system and the interaction between the computing process and the physical process. The ability of large-scale distributed real-time computing provides a new way to solve the problem of real-time coordinated optimization of large-scale distributed devices.
GCPS will enhance the grid's ability to withstand security threats and risks. GCPS will take into account information space security and physical entity security, and innovatively analyze the coupling risk of information interaction, greatly improving the security of the grid. The power grid and information communication network constitute a two-layer complex network. GCPS will establish a mutual coordination mechanism of different protection methods through the research of network theory, fault propagation model, analysis method and trusted computing and security chip technology, and develop the physical network. Adapted information communication network planning and operation methods to achieve coordinated security of information space and physical space.
The future power grid is a wide-area energy transmission platform and market interaction platform, and is a hub and bridge between primary energy and end users. The future energy Internet will be based on the grid information physical integration system, with renewable energy as the primary primary energy, and complex multi-network system formed by tight coupling with other systems such as natural gas network, transportation network and energy storage device. The complementary relationship of various energy sources forms an integrated service system for energy, electricity and information.
