  • DE Scheduling:Scheduling Algorithm for Distributed Grid System
    Computer Engineering, 2008
    Co-Authors: He Ming
    Abstract:

    A dynamic scheduling algorithms studied in references are based on centralized Grid System or part-distributed Grid System, in which there are center node(s) to manage resources. A dynamic scheduling algorithm for the fully distributed Grid System without resource management, named DE Scheduling, is proposed. In the algorithm, the redundant scheduling is used to solve the dynamic of environment, and the time of redundant scheduling is set dynamically to reduce void calculations and balance the load of the System. A group of simulations have been done by using the Internet model with 1 000 nodes based on the evolving model for scale-free network with given mean connected degree. When the number of tasks is from 10 000 to 100 000, the time of redundant scheduling always equals 2, the redundant calculations account of the total amount is less than 0.35%, and reduces with the increasing number of tasks.

  • Automatic Modeling Scheme for Micro-Grid System
    DEStech Transactions on Materials Science and Engineering, 2017
    Co-Authors: Xu Feng
    Abstract:

    The development of micro-Grid System has been attached great importance by many countries in recent years. Micro-Grid System plays an important role in relieving the power shortage. The modeling of micro-Grid System is an important work in the research of micro Grid System. This paper explained the problems existing in the modeling of micro Grid System, and proposed an automatic modeling scheme for micro- Grid System.

  • Size selection of Greenland halibut (Reinhardtius hippoglossoides) in the Norwegian bottom trawl fishery with a newly developed double Grid System
    'Northwest Atlantic Fisheries Organization (NAFO)', 2017
    Co-Authors: Larsen, Roger B., Grimaldo Eduardo, Herrmann Bent, Sistiaga, Manu Berrondo, Brinkhof Jesse, Tatone Ivan
    Abstract:

    Greenland halibut (Reinhardtius hippoglossoides) is a commercially important species in the northeast Atlantic trawl fishery. However, direct fishing for it is not allowed and it can only be harvested as bycatch. We investigated for the first time the size selection of Greenland halibut in a newly developed double steel Grid System designed for the cod and haddock bottom trawl fishery. In this sorting System the first Grid (lower Grid) replaced the lifting panel present in the traditional Sort-V single Grid System often applied in the fishery. Thus, it contributed to the fish sorting process and simultaneously guided fish to the second Grid (upper Grid). However, the results showed that nearly all Greenland halibut escapees left through the second Grid. The release efficiency of the first Grid was estimated to be low, and only 11% of the Greenland halibut entering the Grid zone made contact with this Grid in a way that provided a size-dependent release probability. In contrast, the estimations showed that all Greenland halibut, still in the gear after the first Grid, made contact with the second Grid. However, this contact was suboptimal for size selection of most individuals, as the estimated 50% retention length (based on the morphology of Greenland halibut) was below the expected value. Comparison of the release efficiency of the new double Grid System relative to that of the Grid Systems used in the fishery today revealed that the new System did not improve the release of undersized Greenland halibut. Moreover, we found that the existing Sort-V single Grid System released significantly more Greenland halibut than the new double Grid System

  • ISGT - A technical and economical study of implementing a micro-Grid System at an educational institution
    2015 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2015
    Co-Authors: Matthew S. Purser, Youakim Kalaani, Rami J. Haddad
    Abstract:

    Micro-Grids are among the basic components in the future distributed generation smart Grid Systems. The transmission efficiency improvements and the utilization of renewable energy sources are some of the key advantages of using micro-Grids in power Systems. In this paper, the technical and economical study of implementing a micro-Grid System at an educational institution is discussed and presented. Multiple types of distributed generators were considered including gas-fired generator units, solar photovoltaic, fuel cell, and bio-power Systems. Several simulations were conducted using HOMER and a detailed economic analysis of implementing a micro-Grid System is presented including recommended actions.

  • The progressive smart Grid System from both power and communications aspects
    IEEE Communications Surveys and Tutorials, 2012
    Co-Authors: Chun Hao Lo, Nirwan Ansari
    Abstract:

    The present electric power System structure has lasted for decades; it is still partially proprietary, energy-inefficient, physically and virtually (or cyber) insecure, as well as prone to power transmission congestion and consequent failures. Recent efforts in building a smart Grid System have focused on addressing the problems of global warming effects, rising energy-hungry demands, and risks of peak loads. One of the major goals of the new System is to effectively regulate energy usage by utilizing the backbone of the prospectively deployed Automatic Meter Reading (AMR), Advanced Meter Infrastructure (AMI), and Demand Response (DR) programs via the advanced distribution automation and dynamic pricing models. The function of the power Grid is no longer a System that only supplies energy to end users, but also allows consumers to contribute their clean energy back to the Grid in the future. In the meantime, communications networks in the electric power infrastructure enact critical roles. Intelligent automation proposed in smart Grid projects include the Supervisory Control And Data Acquisition/Energy Management Systems (SCADA/EMS) and Phasor Management Units (PMU) in transmission networks, as well as the AMR/AMI associated with field/neighborhood area networks (FAN/NAN) and home area networks (HAN) at the distribution and end-use levels. This article provides an overview of the essentials of the progressive smart Grid paradigm and integration of different communications technologies for the legacy power System. Additionally, foreseeable issues and challenges in designing communications networks for the smart Grid System are also rigorously deliberated in this paper.
