With the increasing coupling of heterogeneous energy flow, the system characteristics of coupling are becoming more and more obvious and more complicated. The modeling, analysis and control methods of traditional single flow systems have not been applied directly. Therefore, it is necessary to study the modeling of multi-energy flow coupling, the power flow analysis, optimization and control method of heterogeneous energy flow, which plays the role of multi-energy flow synergy to avoid the adverse effects of coupling. This paper summarizes the current research situation of energy Internet at home and abroad from the aspects of modeling of multi-energy flow, power flow calculation and optimal dispatching, and analyzes the existing problems in the research of these aspects.展开更多

Electric veh...A future smart grid must fulfill the vision of the Energy Internet in which millions of people produce their own energy from renewables in their homes, offices, and factories and share it with each other. Electric vehicles and local energy storage will be widely deployed. Internet technology will be utilized to transform the power grid into an energysharing inter-grid. To prepare for the future, a smart grid with intelligent periphery, or smart GRIP, is proposed. The building blocks of GRIP architecture are called clusters and include an energy-management system (EMS)-controlled transmission grid in the core and distribution grids, micro-grids, and smart buildings and homes on the periphery; all of which are hierarchically structured. The layered architecture of GRIP allows a seamless transition from the present to the future and plug-and-play interoperability. The basic functions of a cluster consist of (1) dispatch, (2) smoothing, and (3) mitigation. A risk-limiting dispatch methodology is presented; a new device, called the electric spring, is developed for smoothing out fluctuations in periphery clusters; and means to mitigate failures are discussed.展开更多

To get a big market on the Web, a special security infrastructure would need to be put into place transforming the wild-and-woolly Internet into a network with end-to-end protections. XML (extensible Markup Language) is widely accepted as powerful data representation standard for electronic documents, so a security mechanism for XML documents must be provided in the first place to secure electronic commerce over Internet. In this paper the authors design and implement a secure framework that provides XML signature function, XML Element-wise Encryption function, smart card based crypto API library and Public Key Infrastructure (PKI) security functions to achieve confidentiality, integrity, message authentication, and/or signer authentication services for XML documents and existing non-XML documents that are exchanged by Internet for E-commerce application.展开更多

文摘Chaining watermark is an effective way to verify the integrity of streaming data in wireless network environment,especially in resource-constrained sensor networks,such as the perception layer of Internet of Things applications.However,in all existing single chaining watermark schemes,how to ensure the synchronization between the data sender and the receiver is still an unsolved problem.Once the synchronization points are attacked by the adversary,existing data integrity authentication schemes are difficult to work properly,and the false negative rate might be up to 50 percent.And the additional fixed group delimiters not only increase the data size,but are also easily detected by adversaries.In this paper,we propose an effective dual-chaining watermark scheme,called DCW,for data integrity protection in smart campus IoT applications.The proposed DCW scheme has the following three characteristics:(1)In order to authenticate the integrity of the data,fragile watermarks are generated and embedded into the data in a chaining way using dynamic grouping;(2)Instead of additional fixed group delimiters,chained watermark delimiters are proposed to synchronize the both transmission sides in case of the synchronization points are tampered;(3)To achieve lossless integrity authentication,a reversible watermarking technique is applied.The experimental results and security analysis can prove that the proposed DCW scheme is able to effectively authenticate the integrity of the data with free distortion at low cost in our smart meteorological Internet of Things system.

文摘With the continuous advancement of economic globalization,energy demand is expanding and energy consumption is excessive,which leads to energy shortage.Unreasonable energy use also brings great challenges to the environment and affects the balance of the ecosystem seriously.The rise of the third industrial revolution has injected new vitality into energy system.The construction of energy Internet system,which integrates Internet technology and energy technology,has become a new energy system of sustainable development.It has put forward the reform scheme for the mismatch of energy demand points and environmental pollution.The deepening of sustainable development strategy accelerates the promotion of energy Internet system,promotes the large-scale utilization and sharing of renewable energy.It also provides a new idea for realizing green energy structure and efficient energy utilization.Firstly,based on the core concept of energy Internet system,this paper reviews the relevant research on energy Internet system in academic and industrial circles,and gives the preliminary definition of energy Internet system market.On this basis,it puts forward the development goal of energy Internet system market.It compares the new energy Internet system market with the traditional single energy market,highlighting the characteristics of energy Internet system market,it is reflected in the diversified transformation of market trading subjects,the diversification of market trading objects,the increasing dependence of information technology and the improvement of the matching degree of supply and demand.Then,the integrated architecture of of the energy Internet system market is carried out,and the issues related to the transaction mode and operation mechanism of the energy Internet system market are discussed.Finally,the frontier problems of energy Internet system market are summarized,and the research prospect of energy Internet system market is put forward.
文摘The invocation of World Wide Web (www) first triggered mass adoption of the Internet for public access to digital information exchanges across the globe. To get a big market on the Web, a special security infrastructure would need to be put into place transforming the wild-and-woolly Internet into a network with end-to-end protections. XML (extensible Markup Language) is widely accepted as powerful data representation standard for electronic documents, so a security mechanism for XML documents must be provided in the first place to secure electronic commerce over Internet. In this paper the authors design and implement a secure framework that provides XML signature function, XML Element-wise Encryption function, smart card based crypto API library and Public Key Infrastructure (PKI) security functions to achieve confidentiality, integrity, message authentication, and/or signer authentication services for XML documents and existing non-XML documents that are exchanged by Internet for E-commerce application.
文摘To realize the ultimate vision of Internet of Things(IoT),only depending on terrestrial network is far from enough.As a supplement and extension of terrestrial network,satellite network can offer powerful support to realize the depth and breadth of the coverage.However,existing satellite networks are usually designed for particular purposes.Moreover,traditional satellite networks and terrestrial networks are developed and operated separately,consequently they cannot meet the need of network flexibility required by IoT.In this paper,a space-terrestrial architecture is conceived for constructing a spaceterrestrial based IoT(ST-IoT) system.Additionally,a reliable identification procedure,an integrated access and communication procedure,as well as a clustering cooperative transmission strategy are also presented.
