Research On Reliable Collaborative Management Of Information And Energy In 5G Smart Grid

In the 5G era,the network presents the trend of interconnection of everything,informationcentricity,and virtualization.Its characteristic of low-latency,wide connectivity,strong robustness can meet the differentiated service demand of various vertical industries(such as energy,industrial control,transportation,etc.).The smart grid is considered to be a very representative application scenario of 5G.The introduction of 5G technology provide significant support for efficient information transmission,reliable energy distribution and the flexible resources allocation in the smart grid.As the critical infrastructure of country,power network is the backbone of modern industrial and economic activities.The 5G technology has continuously driven the innovation and development of novel smart grid.Smart grids can provide energy more efficiently and process various events in real time with the aid of remote sensing and measurement technology,advanced decision-making technology and other information technology.Unfortunately,it also brings the new challenges to collaborative and reliable management of information and energy.First of all,the reliable transmission of power information is the key to ensure the reliability of the smart grid.The integration of massive consumer terminals and measuring equipment has not only facilitated the operation of the power grid,but also brought great pressure on information transmission.It bring the delay,high reliability,and energy saving requirements for communication mechanism.Secondly,the communication network of 5G smart grid is characterized by information-centricity.The existing single-source,centralized power grid urgently needs innovation to realize the coordination and wide-area distribution of information and energy in the distributed 5G smart grid.Finally,5G uses network function virtualization to realize the management and deployment of information function,while energy equipment is still gigantic and function-specific.That will hiders the interaction of resources,the update and flexible deployment of smart grid functions,which reduce the availability of the 5G smart grid.Therefore,this thesis has thoroughly studied the information and energy management mechanism of 5G smart grid to ensure the real-time and reliable transmission of information.We attempt to realize the energy management and resource scheduling in the smart grid integrated with distributed equipment,and improve the reliability of the smart grid.To solve those problems in 5G smart grid,the innovative works and contributions of this thesis are summarized as follows:1)A communication performance optimization mechanism called QPER is proposed for information-centric smart grid in 5G.To meet the different QoS requirements of the data generated by the power equipment,the network calculus is used to predict the QoS of data link,the routing selection and routing planning is proceeded based on the path status to achieve low latency and high reliability of data transmission in the 5G smart grid.2)An energy distribution and energy cache mechanism for 5G smart grid is proposed.Inspiring by information centric network architecture,a novel energy distribution architecture called energy-centric smart grid is designed.Our work construct a new energy router to achieve two-way transmission of data packets and energy packets and realize multiple transmission of energy.With the help of energy cache,smart grid can reduce energy waste,improve the energy availability and realize rapid energy response.3)A coordinated energy and information function virtualization architecture and reliability scheduling mechanism are proposed.We construct the energy function virtualization framework and IEC61850-based virtualization solutions to support the access of distributed energy function equipment.The machine learning optimized stochastic network calculus is used to model the resource demand processing.Based on the performance assessment result,we design a noncooperative game scheduling scheme for reasonable deployment of resources.In summary,this article conducts in-depth research on information routing,information and energy coordinated distribution,resource scheduling and others in 5G smart grid.Then we proposes a reliable energy and information management mechanism for 5G smart grid and verifies the correctness,superiority,and effectiveness of the proposed mechanism on the mainstream experimental platform.Our research work provides theoretical and technical support for the further development of 5G smart grid.
