Energy Sharing

In the future, energy Internet will gradually replace the traditional power network since it enables flexible energy sharing for consumers. Consensus algorithm achieved good performance in solving economic dispatch problem in microgrid system whereas the difficulty is finding a consensus variable. By means of choosing the incremental generator cost of each energy local area network (ELAN) as the consensus variable, the economic dispatch problem can be solved. Using the stochastic gossip-based algorithm as the basic framework, the economic dispatch problem can be solved in a distributed manner. In order to meeting the real-time load requirement in time under the fixed communication topology, the fluctuation of each ELAN will do the consensus update at the same time. The result of a representative case is presented to illustrate the performance of the proposed two-level stochastic gossip-based consensus algorithm.

Power System Model

For marine engineer training, marine power system analysis and fault diagnoses, a marine power system simulator (MPSS) is proposed here. It has been developed by applying system simulation techniques. The main techniques employed were marine power system modeling, microcomputer control, and local area network communication. Some functions and typical fault simulations produced with the MPSS are introduced. These operations are particularly useful for marine engineer training. A marine power system model is built by applying the power system dynamic stability theory. The power system model is the most important element in the simulator. The system model is made of a diesel engine generator, induction motor, power network, and so on. Many simulation results were obtained, such as starting the lubricating oil pump and a power network three-phase ground fault. Because the system offers online control, local area network communication, and human-machine interface of information, this MPSS is used extensively in marine engineer training where the standard is professional skill in marine electrical technology. The system has been used to meet the standards of the STCW78/95 international convention in many marine companies and training centers in China with good results.

This report focusses on the planning and realization of an interdisciplinary local area network (LAN) for medical research at the University of Heidelberg. After a detailed requirements analysis, several networks were evaluated by means of a test installation, and a cost-performance analysis was carried out. At present, the LAN connects 45 (IBM-compatible) PCs, several heterogeneous mainframes (IBM, DEC and Siemens) and provides access to the public X.25 network and to wide-area networks for research (EARN, BITNET). The network supports application software that is frequently needed in medical research (word processing, statistics, graphics, literature databases and services, etc.). Compliance with existing “official” (e.g., IEEE 802.3) and “de facto” standards (e.g., PostScript) was considered to be extremely important for the selection of both hardware and software. Customized programs were developed to improve access control, user interface and on-line help. Wide acceptance of the LAN was achieved through extensive education and maintenance facilities, e.g., teaching courses, customized manuals and a hotline service. Since requirements of clinical routine differ substantially from medical research needs, two separate networks (with a gateway in between) are proposed as a solution to optimally satisfy the users’ demands.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

This study aims to design a LAN network for data backup systems that are in accordance with certain aspects such as the selection of network design, network hardware, network transmission media, network connection devices, and network operating systems. Data is the most important thing for everyone, data can usually be reused even though it has not been used for some time, and therefore data storage is a serious problem that must be considered. Data on the server computer is very important to be maintained so that a backup process is needed on that data to another computer that is used as a backup in the event of damage to the hardware and software of the server computer. FTP is one of the solutions to the problems faced above,where FTP can be used to process the download and upload between the server and client computers. This design uses the Autobot system. The expected benefit in designing this LAN is that the existing network at SMP Negeri 6 Pekanbaru is not only used by employees and employees but can be used and enjoyed by teachers and students to access the internet anywhere as long as it is still within the scope of the SMP Negeri 6 area Pekanbaru.
