This paper presents an adaptive protection dual strategy based on Relay Agents distributed along strategic locations of a microgrid. The architecture is based on the application of Relay Agents and three additional agents named Selectivity, Configurator, and Coordinator, executed in a microgrid central controller. The multi-agent strategy is divided in two complementary approaches, named online and offline. The online approach operates on fast protection, centralizing key information and selecting actions based on expert systems, thus requiring a communication infrastructure to eventually operate circuit breakers. The offline approach works as a backup protection in case of communication failures and delays, operating by adjusting relay settings in real time. The dual multi-agent protection strategy has been simulated to verify the performance of microgrid protection both in connected and isolated modes.

基于多智能体双策略的微电网自适应保护

本文提出了一种基于沿微电网战略位置分布的中继代理的自适应保护双重策略。该架构基于中继代理和三个名为 Selectivity、Configurator 和 Coordinator 的附加代理的应用,在微电网中央控制器中执行。多代理策略分为两种互补的方法,称为在线和离线。在线方法运行在快速保护、集中关键信息和基于专家系统选择动作的基础上,因此需要通信基础设施来最终操作断路器。离线方法可在通信故障和延迟的情况下作为备用保护,通过实时调整继电器设置进行操作。
