Comunicação Resiliente e Autonômica para Proteção e Controle das Smart Grids

In smart grids, the power system communication is interconnected, including final users. The broad usage of distributed energy resources in distribution networks introduces the need of protective relaying schemes similar to those used in high voltage networks. Hence, power systems experience an increased demand for resilience in the distribution communication network. However, the resilience methods currently in use still cannot meet these protection requirements. This work proposes ARES, a framework for autonomic and resilient communication for smart grids. The proposal is evaluated and compared to the main proposals of the literature. ARES presents maximum recovery time of 610 microseconds, which is an important advance compared to the other proposals. In addition, ARES is transparent to end devices, keeping compatibility with legacy measurement and actuation devices.
