  • A Model-Based Design of Distributed Automation Systems for the Smart Grid: Implementation and Validation
    Energies, 2020
    Co-Authors: Davide Della Giustina, Amelia Alvarez De Sotomayor, Alessio Dede, Francisco Ramos
    Abstract:

    The paper aims at describing a model-based approach to design automation logics for fault location and supply restoration in medium voltage distribution networks. The application of automation functions along medium voltage feeders and, in particular, the installation of protection devices in secondary substations mandates the design and the Implementation of complex logics to coordinate the operations of this hardware in case of fault occurrences. This synchronization is realized with the exchange of IEC 61850 GOOSE messages, but the correct usage of this information must be implemented in each protection device through dedicated logics, which are not in the common out-of-the-box system configurations. To support the introduction and the design of these logics, an automata-based approach has been proposed and successfully demonstrated in a real environment in the European research project IDE4L. This formal methodology has been introduced to simplify the design phase and to standardize the logics implemented in the protection prototypes realized in the project. The same models have also been used in the Implementation phase with a semi-automatic code generation procedure, considering as a target system the software programmable logic controllers (soft-PLCs), available on the protection devices. Based on the test results and the short time to set up the test bench, this approach proved to be a reliable and effective way to implement complex medium voltage (MV) automation logics such those needed in modern Smart Grids.

  • requirements driven Implementation of Smart Grid applications and technology
    Conference on Industrial Electronics and Applications, 2016
    Co-Authors: Muhammad Numan, Jimmy Baimba Brima, Ibrahim J Sowe, Zhou Ming, Kamran M Bodla
    Abstract:

    Energy efficiency and power crises are the critical issues that the globe is facing nowadays. Generation diversification, Demand Response, renewable energy accommodation, and reduction of Carbon dioxide emission are some of the issues that cannot be covered within the limitation of the current Grid system. Smart Grid has revolutionized the generation, Distribution, and Consumption of electricity by integrating intelligent control, sensing and communication in daily operation of the electric Grid. The goal of the Smart Grid is to be environmentally sustainable, for the deployment of this trending technology is a must. This paper addresses the issues that would be faced in the Implementation of the Smart Grid technology, policy consideration to maximize the benefit of Smart Grid and enhance the benefit over cost ratio. It explains the three sectors where the Smart Grid applications can be seen with challenges in bottom-up design, and overview of Smart Grid for utilities. A top-down scheme is presented which can help in eliminating the challenges and barriers in the Smart Grid Implementation. Finally cost vs. benefit analysis is made to prove the effectiveness of this trending technology in the power sector.

  • Advanced Power Distribution System Configuration for Smart Grid
    IEEE Transactions on Smart Grid, 2013
    Co-Authors: Hee-sang Shin
    Abstract:

    Power distribution systems should meet demands such as high reliability, efficiency, and penetration of renewable energy generators (REGs) in a Smart Grid. In general, power distribution systems are radial in nature. One-way power flow is the advantage of a radial system. However, the introduction of REGs causes bidirectional power flow. Furthermore, there are limits to improvements in reliability and efficiency in a radial system. Therefore, the upgrading of primary feeders from a radial to a loop configuration has been considered in the Korea Smart Distribution Project. An advanced power distribution system (APDS), in which primary feeders operate in a loop configuration, has been explored in this paper. First, the design scheme of a conventional power distribution system configuration that adopts distribution automation is introduced. Subsequently, an upgrading scheme of loop configuration using normally opened tie switches and a tie switch selection algorithm for loss minimization are described. Finally, the advantages of the upgraded configuration are reported through case studies. It is observed that the APDS configuration can integrate more REGs from the viewpoint of voltage regulation. An advanced distribution system allowing greater use of REGs will be a major contribution to Smart Grid Implementation.

  • a roadmap for the Implementation of Smart Grids in brazil
    IEEE PES Innovative Smart Grid Technologies Conference, 2012
    Co-Authors: Nelson Kagan
    Abstract:

    The presentation deals with a project that established a roadmap for the Implementation of Smart Grids in Brazil. The project was divided into 7 research blocks, concerning the main aspects in any Smart Grid Implementation, such as Smart metering, automation, distributed resources, IT, telecommunication and public policies. A novel methodology that takes into account the Country's diversity was developed to establish network evolutions towards Smarter Grids, considering different possible scenarios. Related costs and benefits were then evaluated‥
