Smart grid is willing to make full advantage of distributed clean energy to alleviate energy crisis and environmental problems. However, distributed renewable energy is usually invisible and uncontrollable for the current power system, and there are intermittent problems in its generation. therefore, how to achieve the power balance, maintain safe operation, and ensure the reliability and quality of power supply when the distributed energy reaches a high penetration in the grid is a huge challenge. Blockchain as one of the research hotspots brings about new solution approach to the dilemma. the two fields have many commons on decentralization, autonomy, marketization and intelligence. In this paper, we discuss the feasible scheme of the integrated system and add fog computing to reduce costs. Considering the realization of system, we choose Hyper Fabric as the basic structure and add verifiable random function to the consensus aimed to improve randomness and security in the encrypted election. Meanwhile, in order to satisfy the business requirements, a flexible adjustment method based on Deep Q Learning algorithm is designed to realize the joint optimization of throughput, latency and storage cost. the proposed scheme provides the advantages including privacy, flexibility, extensibility and implantation simplicity.

grid is a research hot point in computer industry. In this paper, Mobile Agents are used as carriers of distributed tasks in grid, which can migrate between grid services autonomously and intelligently. Some Mobile Agents transmit a great deal of data in high-bandwidth and high-delay grid environment. According to features of grid and Mobile Agents, a new multiple connection mechanism is proposed. Experiments have proved that this mechanism, in which both transmission delay and package loss is thought as indicator of congestion, have higher transmission speed than the mechanism in which only package loss is thought as indicator of congestion.

the concept of using distributedcomputing to supply video games to end users has been growing in popularity. Internet cafes are one potential application for this concept. We consider a cloud-based model for Internet cafes where servers provide virtual machines with different specifications in order to meet different kinds of user demand (web browsing, low end gaming, medium end gaming, and high end gaming). In an Internet cafe, users arrive throughout the day with different demands and different durations for which they stay. Given the user demand over time and a fixed hardware set-up of servers, the task then consists of choosing which users to accept and how to allocate the accepted users to the servers in order to maximize the total profit of the Internet cafe. We formulate an integer programming model for computing an optimal choice of users to accept together with an efficient allocation of accepted users to servers. Computational results show that, when allocating users efficiently, using a cloud-based setting with servers providing virtual machines that exactly meet the users' demands can greatly improve resource efficiency in Internet cafes compared to classical zoning models that use desktop computers. At the same time, the total profit obtained from accepting users can be improved significantly due to the added flexibility when using an optimized user acceptance strategy.

Use of renewable and non-renewable sources for distributed energy generation is more efficient than using only one of them standalone. For such distribution system stand-alone grid is considered having no co-ordination with conventional gridthe proposed system is connecting outputs of different renewable sources to grid via Radio Frequency (RF) communication module. the actual working mechanism of RF communication module is to match phase angle of AC output generated from renewable sources, and in turn combining matching power information of these outputs into stand-alone smart grid Matching phase angles of different outputs from renewable sources, plays extremely crucial role, otherwise grid and other circuitry will get hit by unforeseen damage and casualties may occur. Furthermore, this paper demonstrates the research in area of energy grid with prototype model being build and related findings are shared along with insightful statistically processed real time system data analysis. this paper proposes more in depth insights into subject matter with continuation to our previous paper [1].

grid systems have emerged as a means of sharing computational resources and information. Providing services for accessing, sharing and modifying large databases is a crucial task for grid management systems. this paper proposes an artificial neural network (ANN) prediction mechanism that provides an enhancement to data replication solutions within grid systems. Current replication services often exhibit an increase in response time, reflecting the problems associated withthe ever increasing size of databases. the proposed replica selection prediction model will locate files for incoming jobs using users' historical executions. Experimental results demonstrate the significant gains achieved by the proposed solution in terms of high accuracy and low overheads.

grid system software is inherently complex, hard to build and maintain. In this paper, we propose a self-managing building block: grid Unit, which facilitates constructing grid system with higher availability and lower management overhead. We present an agent organization as autonomic management framework, and propose a self-recovering protocol to eliminate most of tough jobs from system administrator's routines. the system has been deployed on Dawning 4000A since 2004, the biggest node for China grid system. We have done extensive experiments to evaluate grid Unit, and the collected log data shows the availability of a grid parallel process management service, built on the basis of grid Unit, reaches 99.997%.

Numerous geographical models distributed in different geographical locations or cyberspaces lead to difficulties for sophisticated geographical problems solving due to the heterogeneity and decentralization. grid computer technology provides a new way to solve problems in geographical sharing and service based on geospatial information technology. the method for understanding, describing and representing geographical models and geographical model service based on WSRF are discussed in this paper, and distributed geographical model sharing service framework is proposed. A prototype of distributed heterogeneous geographical models service platform is developed, and some experiments are implemented to examine the proposed methods. the proposed platform can provide a geographical resource sharing environment for geographical problem solving and geographical experimental in cyberspace.

Computational grids, which make large-scale simulation possible, are valuable infrastructure for users such as research scientists, and many users benefit from the computational capabilities of high-performance resources. However, concerns exist about improper use by malicious users because of the processing ability of Computational grids. Currently, both normal users and administrators demand safety and reliability for large distributedcomputing. this paper proposes an approach based on the concept of ISAC for administrators to support incident response and forensic analysis, using gathered resource information and user activities in a Computational grid environment.
