  • PREVENT DER CHAOS: a Guide to Selecting the Right Communications Protocols for DER Management
    PREVENT DER CHAOS: A Guide to Selecting the Right Communications Protocols for DER Management Published January 2020 DISCLAIMERS Why QualityLogic’s Recommendations QualityLogic occupies a unique role in the development and implementation of communications protocols for DER management by vendors and utilities. Developing and supporting test tools for DER protocols provides an unparalleled knowledge of both the technologies and eco-systems working with the technologies. We have the privilege of advising utilities, vendors, alliances, research labs and regulators on the capabilities and implementation of specific DER protocol standards. We are constantly asked for both training and recommendations for the selection of a standard for specific applications. The increasing interest in the monitoring and management of DER resources begs for the type of analysis and guidance QualityLogic provides in this Guide. These Recommendations are a Starting Point The recommendations contained in this guide are those of QualityLogic and do not represent any other organization, alliance, company or government entity. The Recommendations should be viewed as a starting point and are based on models for use cases and deployment strategies. For specific applications an independent analysis should be conducted which may yield different results. The Recommendations also use a “snapshot” of the current state and adoption of protocols which is subject to change over time and may lead to different results than included here. To find out more about how recommendations were developed, or how to conduct an analyis for your situation contact us at [email protected]. ACKNOWLEDGEMENT QualityLogic would like to thank our long-time associate, Mark T. Osborn, for his major contribution to this white paper.

    FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Smart Reconfiguration of Distribution Grids using Agent-based Technology Matheus Macedo Lopes Dissertation conducted under the Master’s in Electrical and Computers Engineering Program - Major Energy Supervisor: Prof. Vladimiro Miranda , Ph.D. Co-Supervisor: Prof. Diego Issicaba , Ph.D. July 28, 2016 © Matheus Macedo Lopes, 2016 Resumo As manobras de isolamento para reconfiguração em redes de distribuição de média tensão são tradicionalmente manuais ou dependem de decisões tomadas pelos operadores de rede. A abor- dagem proposta assume uma arquitetura onde os agentes interagem em um ambiente de rede de distribuição simulado a partir do estabelecimento de metas projetadas seguindo o paradigma de orientação mulit-agente. A aplicação é implementada de tal forma que agentes AgentSpeak in- teragem entre eles através de uma comunicação baseada em ato de fala/comunicação, bem como com um ambiente desenvolvido em linguagem JAVA. Neste contexto, esta tese propõe a modelagem e verificação de soluções baseadas em agentes para apoiar as operações de reconfiguração em redes de distribuição em nível de média tensão. A metodologia foi utilizada para apoiar as actividades dos operadores de redes de distribuição por meio de planos de restabelecimento de energia para ajudar em casos de falhas permanentes. As abordagens empregadas para arquitetura de agentes para a reconfiguração foram baseadas em modelo hierárquico e uma abordagem totalmente descentralizada. A capabilidade dos agentes foram desenvolvidas prevendo as possiveis aplicações do sistema de distribuição com foco em procedimentos de gestão des interrupções de service. As abordagens foram testadas em um ali- mentador teste trifásico do IEEE de 123 nós.
