Research On Smart Grid Data Management Mechanism From The Perspective Of Blockchain Technology

At present,the research on the management of data and information of Chinese electric power companies is in its infancy.With the upgrading of smart grids,new power equipment and electric power information systems,massive data awaits screening,analysis and processing.In the process of power data management,a large number of equipment fault records need to be traced and power transaction information inquired.A data information management method with traceability,undeniability,and non-repudiation is needed.Compared with the previous power data,the existing power data has changed a lot,not only the variety of formats has also become more diverse,mainly reflected in two aspects:On the one hand,these data sources come from a wide range of sources,such as equipment operation,intelligent system automatic feedback,etc.;On the other hand,the data structure of power companies differs greatly.For example,the data contains text information,picture information,and power data information.With the continuous promotion of blockchain technology,this technology is expected to solve the problems of low security and low accuracy in power grid data management.This research takes the wide application of blockchain technology as the research background,and the data information management of smart grid as the research object.It focuses on the operation mechanism of the smart grid data management system from the perspective of blockchain.Data is analyzed and processed more efficiently,and blockchain technology is applied to smart grid data management.The study first restructured the smart grid data management platform by analyzing the smart grid data information and blockchain technology characteristics;Then try to build a smart grid data management system using the blockchain alliance technology,use the distributed storage,asymmetric encryption,consensus mechanism,smart contract and other characteristics of the blockchain technology to solve the problems of grid data storage and application,and build a smart grid new ecological model of data optimization management;Finally,it deeply studies the collection and extraction of power data,fusion encryption,information transmission,maintenance and sharing,and proposes a new information management model,which provides specific and practical implementation solutions for the construction of smart grid data management system and the deep integration of blockchain technology.This research results use the "Geth" platform to describe the program simulation process of smart grid data management,analyze the economic and social benefits of smart grid data management applications,and closely integrate smart grid data management with the actual application of blockchain to establish a complete Grid data information optimization management system.And put forward suggestions to promote the blockchain power grid data management system to the energy trading market,smart micro-grid and virtual power plants,in order to effectively record power data information,accelerate business innovation,mine the value of data,and further enhance power data The management efficiency to achieve research results can be implemented.
