  • Power 2000 a new concept for the Electrical Power Industry in the twenty first century
    Technological Forecasting and Social Change, 1993
    Co-Authors: Dan Weiner
    Abstract:

    Abstract A new concept for an alternative structure of the Electrical Power Industry in the twenty-first century is outlined. It is argued that through a transition period, the existing dynamic for change driven by technological and economic development would shift the main means of production from mechanical ones into high technology devices utilizing the achievements of “mechatronics”. It is assessed that a biological paradigm would prevail, examples of which are presented to prove its influence on energy systems. These developments will affect Power economies, with a direction sketched towards an increase in the use of renewable energies.

  • Recent progress in applications of in-fibre Bragg grating sensors
    Optics and Lasers in Engineering, 1999
    Co-Authors: Y. J. Rao
    Abstract:

    In-fibre Bragg grating (FBG) sensor technology has become one of the most rapidly progressing sensing topics of this decade in the field of optical fibre sensors. FBG sensors are currently emerging from the laboratory to find practical applications. Rapid progress has been made in both sensor system developments and applications in recent years. This article presents a systematic review of recent progress in applications of FBG sensors in large composite and concrete structures, the Electrical Power Industry, medicine, and chemical sensing.

  • Recent progress in in-fiber Bragg grating sensors: applications
    Optical and Fiber Optic Sensor Systems, 1998
    Co-Authors: Y. J. Rao
    Abstract:

    In-fiber Bragg grating (FBG) sensor technology has become one of the most progressing sensing topics of this decade in the field of optical fiber sensor technologies as FBG sensors are capable of measuring a wide range of parameters and have potential for simultaneous measurement of multi- parameters. In recent years, rapid progress has been made, in particular, in sensor system developments and applications. The fundamental aspects of the FBG sensor technology have been reviewed recently by the author. As a complementary article, this review paper concentrates on the recent progress in applications of FBG sensors for large composite structures, Electrical Power Industry and medicine. Also, recent progress in sensor system developments associated with these applications are addressed.

  • application layer security proxy for smart grid substation automation systems
    IEEE PES Innovative Smart Grid Technologies Conference, 2013
    Co-Authors: Dong Wei, Florin Darie, Ling Shen
    Abstract:

    America's Electrical Power Industry, in conjunction with government, is developing Smart Grid technologies to improve Electrical Power efficiency and reliability. This move is creating challenges in transitioning originally isolated proprietary systems to more open ones, connecting them to enterprise-level and other networks without compromising their original control performance. Application layer communication is the weakest link in terms of security and the unique challenges of Smart Grid applications have not been addressed yet. This paper presents a security solution based on application layer security proxy, which deploys deep packet inspection and role-based access control technologies, for smart grid substation automation systems. The testing of the prototype system shows that it is able to block illegitimate packets without interrupting its communication session.

  • implementation of relaxed acid properties for distributed load management in the Electrical Power Industry
    International Conference on Ubiquitous Information Management and Communication, 2013
    Co-Authors: Lars Frank, Rasmus Ulslev Pedersen
    Abstract:

    The consistency of data in central databases is normally implemented by using the ACID (Atomicity, Consistency, Isolation and Durability) properties of a DBMS (Data Base Management System). Distributed databases with high performance and availability do not have the traditional ACID properties because long duration locks will reduce the availability and the write performance. Another reason for not using traditional ACID properties in distributed systems is that the systems often are heterogeneous. The problems of the missing ACID properties may be avoided by using relaxed ACID properties, i.e. from an application point of view; the system should function as if all the traditional ACID properties had been implemented. The distributed relaxed atomicity property manages the workflow of a transaction in such a way that either all the updates of the global transaction are executed (sooner or later) or all the updates of the global transaction are removed/compensated. The objective of this paper is to describe how relaxed ACID properties may be implemented in distributed heterogeneous systems like the Smart Grid Conceptual Model that is used for load management in the Electrical Power Industry.
