    Integrating an agent-based wireless sensor network within an existing multi-agent condition monitoring system

    The use of wireless sensor networks for condition monitoring is gaining ground across all sectors of industry, and while their use for power engineering applications has yet been limited, they represent a viable platform for next-generation substation condition monitoring systems. For engineers to fully benefit from this new approach to condition monitoring, new sensor data must be incorporated into a single integrated system. This paper proposes the integration of an agent-based wireless sensor network with an existing agent-based condition monitoring system. It demonstrates that multi-agent systems can be extended down to the sensor level while considering the reduced energy availability of low-power embedded devices. A novel agent-based approach to data translation is presented, which is demonstrated through two case studies: a lab-based temperature and vibration monitoring system, and a proposal to integrate a wireless sensor network to an existing technology demonstrator deployed in a substation in the UK

    The Clarens Web Service Framework for Distributed Scientific Analysis in Grid Projects

    Get PDF
    Large scientific collaborations are moving towards service oriented architecutres for implementation and deployment of globally distributed systems. Clarens is a high performance, easy to deploy Web Service framework that supports the construction of such globally distributed systems. This paper discusses some of the core functionality of Clarens that the authors believe is important for building distributed systems based on Web Services that support scientific analysis

    Power Systems Monitoring and Control using Telecom Network Management Standards

    Get PDF
    Historically, different solutions have been developed for power systems control and telecommunications network management environments. The former was characterized by proprietary solutions, while the latter has been involved for years in a strong standardization process guided by criteria of openness. Today, power systems control standardization is in progress, but it is at an early stage compared to the telecommunications management area, especially in terms of information modeling. Today, control equipment tends to exhibit more computational power, and communication lines have increased their performance. These trends hint at some conceptual convergence between power systems and telecommunications networks from a management perspective. This convergence leads us to suggest the application of well-established telecommunications management standards for power systems control. This paper shows that this is a real medium-to-long term possibility

    Advanced Techniques for Assets Maintenance Management

    Get PDF
    16th IFAC Symposium on Information Control Problems in Manufacturing INCOM 2018 Bergamo, Italy, 11–13 June 2018. Edited by Marco Macchi, László Monostori, Roberto PintoThe aim of this paper is to remark the importance of new and advanced techniques supporting decision making in different business processes for maintenance and assets management, as well as the basic need of adopting a certain management framework with a clear processes map and the corresponding IT supporting systems. Framework processes and systems will be the key fundamental enablers for success and for continuous improvement. The suggested framework will help to define and improve business policies and work procedures for the assets operation and maintenance along their life cycle. The following sections present some achievements on this focus, proposing finally possible future lines for a research agenda within this field of assets management

    Agglomerative Magnets and Informal Regulatory Networks: Electricity Market Design Convergence in the USA and Continental Europe

    Get PDF
    The absence of one broadly accepted design template for liberalised electricity markets induces regulatory competition and institutional diversity. Focussing on continental Europe and the USA, this analysis explores how agents and structures accelerate or impede the move to one standard market design in the electricity sector. It reveals that market design convergence in Europe is driven by the 'Florence Consensus,' a tripartite coalition between the European Commission fostering European integration and the internal market, informal regulatory networks between grid operators, standardisation authorities and regulators, who have been coordinating their actions in the 'Florence Forum,' and epistemic communities exemplified in the Florence School of Regulation. In contrast, the United States' Federal Energy Regulatory Commission lacks support among politicians, many states' public utility commissions, the neo-liberal intelligentsia and even industrial lobbying groups to effectively push for a standardised market design. However, design convergence in the USA may be induced by the gradual expansion of multi-state markets operated by regional transmission organisations.Electricity, Deregulation, Regulatory Competition, Policy Diffusion

    Local Broadband Access: Primum Non Nocere or Primum Processi - A Property Rights Approach

    Get PDF
    High-speed or "broadband" Internet access currently is provided, at the local level, chiefly by cable television and telephone companies, often in competition with each other. Wireless and satellite providers have a small but growing share of this business. An influential coalition of economic interests and academics have proposed that local broadband Internet access providers be prohibited from restricting access to their systems by upstream suppliers of Internet services. A recent term for this proposal is "net neutrality." We examine the potential costs and benefits of such a policy from an economic welfare perspective. Using a property rights approach, we ask whether transactions costs in the market for access rights are likely to be significant, and if so, whether owners of physical local broadband platforms are likely to be more or less efficient holders of access rights than Internet content providers. We conclude that transactions costs are likely to be lower if access rights are assigned initially to platform owners rather than content providers. In addition, platform hardware owners are likely to be more efficient holders of these rights because they can internalize demand-side interactions among content products. Further, failure to permit platform owners to control access threatens to result in inadequate incentives to invest in, to maintain, and to upgrade local broadband platforms. Inefficiently denying platform owners the ability to own access rights implies a need for price regulation; otherwise, there will be incentives to use pricing to circumvent the constraint on rights ownership. Price regulation is itself known to induce welfare losses through adaptive behavior of the constrained firm. The impact on welfare might produce a worse result than the initial problem, assuming one existed. Much of the academic interest in net neutrality arises from the belief that the open architecture of the Internet under current standards has been responsible for its remarkable success, and a wish to preserve this openness. We point out that the openness of the Internet was an unintended consequence of its military origins, and that other, less open, architectures might have been even more successful. A policy of denying platform owners the ability to own access rights could freeze the architecture of the Internet, preventing it from adapting to future technological and economic developments. Finally, we examine the net neutrality issue from the perspective of the "essential facility doctrine," a tool of the common law of antitrust. The doctrine establishes conditions under which federal courts will mandate access by competitors to the monopoly platform of a vertically-integrated firm. Because local broadband Internet access is not today a bottleneck monopoly (there are several competitors and the market is at an early stage of development), the essential facilities doctrine would not permit reassignment of access rights from platform owners to competitors. We conclude that "net neutrality" is a welfare-reducing policy proposal.Technology and Industry, Regulatory Reform
