Abstract
Description
Technical Field
[0001] The present application relates to the field of electric power technology, and in particular to an Internet of Things trust analysis method and system for energy storage cluster frequency modulation transactions. Background Art
[0002] The three major application scenarios of 5G are a further deepening of the three major application scenarios of data transmission solutions in the power Internet of Things. Relevant experts and scholars at home and abroad have also divided the power Internet of Things business according to the three major application scenarios of 5G and carried out relevant research work.
[0003] The eMBB scenario mainly meets the needs of some high-bandwidth services, which is an enhancement of data collection application scenarios and business information transmission scenarios. At present, the application of the power Internet of Things in this regard is mainly the big video of the power grid, including substation robot inspection, transmission line drone online monitoring, distribution room video monitoring, mobile on-site construction operation control and emergency on-site self-organizing network comprehensive application. Many researchers have tried to apply 5G technology to certain scenarios and have achieved certain results.
[0004] In terms of trust calculation, there are many research results, such as: calculating the reputation value of nodes in the global scope through multiple iterations of the trust chain, introducing probability theory to solve the trust problem, and giving a trust model algorithm performance based on Bayesian network. The algorithm's time decay and penalty factor are considered when calculating trust, which improves the accuracy of the algorithm and its ability to resist strategic attacks. Trust is dynamically established and developed, and its development trend has certain rules. At the same time, there is a certain correlation between two adjacent transactions. The existing algorithms do not well reflect the time correlation, context correlation and development trend of trust. In order to better describe these characteristics of trust, based on the existing Markov chain model, steady-state probability is introduced to describe the development trend of trust. After each transaction is completed, the transfer matrix is dynamically updated to more accurately describe the context correlation of trust. At the same time, time decay factor and penalty incentive factor are added to improve the algorithm's ability to resist attacks. However, there is still little research on the existing technology of the Internet of Things trust calculation method for energy storage cluster frequency regulation transactions. Therefore, there is an urgent need for an Internet of Things trust analysis method for energy storage cluster frequency regulation transactions to calculate the trust of the power Internet of Things and evaluate the impact of trust on energy storage cluster frequency regulation transactions.
