Research On Intelligent Electricity Interaction Mode And Security

With the development of communication and information technology,smart grid is developing in a direction of various interactions such as multi-friendliness flexibility and diversity,two-way interaction and high efficiency.Intelligent usage of electricity has established a bridge between the power grid and users,which ensures a timely information interaction and meets the requirements of users.It is also an important means to guarantee the stable operation of power grid and improve service quality.The industrial Internet integrates device access,acquisition and analysis of data and service application,therefore ensuring the connectivity of intelligent interaction of the participating devices and providing a new idea for intelligent power interaction.However,the existing security system of the Industrial Internet couldn't meet the requirements of intelligent power interaction.Therefore,designing a security protection system suitable for interactive mode is of great significance.Firstly,this thesis analyzes the cloud platform architecture and security architecture of the Industrial Internet.On account of the relatively closed state of the intelligent power interaction system,the intelligent interactive research based on the industrial Internet cloud platform is carried out,and the general architecture of intelligent electricity interaction based on the industrial Internet cloud platform is designed,which ensures the connectivity between interactive participating devices.Secondly,this thesis studies the energy consumption characteristics models of interactive devices,analyzes the requirements of users,service providers and power grid in the environment of the Industrial Internet.In order to meet the needs of all parties involved in the interaction,five kinds of interactive modes based on the Industrial Internet are designed,including direct interaction mode,indirect interaction mode,housekeeper interaction mode,delegated interaction mode and controlling interaction mode,and five kinds of application scenarios are designed,which solves the problem that the current intelligent electricity interaction system cannot provide satisfactory services for users.Finally,in view of the problem that the existing Industrial Internet security system cannot meet the interactive security requirements,this thesis designs an security system combining two-way authentication and data security.For the five modes,different methods for data security are designed,which not only saves encryption time and improves the efficiency of interaction,but also solves the problem that the data confidentiality and integrality are threatened since there are numerous interactive participants.Moreover,the digital signature can prevent repudiation and make every step of the interaction traceable.Taking Suzhou network topology as an example,time of the data encryption and decryption of the interactive process is simulated.The result indicates that the method is effective.
