| Resumo: | The evolution of the Smart Grid towards the Internet of Things (IoT) is an evolution of
the electrical system, it is a natural trend, and it foresees great importance in the scope
of mission-critical infrastructures for all countries. The IoT-defined Smart Grid system
upgrade will potentially lay the groundwork to achieve future benefits, enabling new
opportunities in the Smart Grid market to arise and add value through smart innovations
and also to ensure better reliability and energy efficiency, which can lead to a reduction in
the production cost and systems maintenance at the same time. The fundamental step that
is behind the IoT-defined Smart Grid system upgrade lies in the need to adapt the smart
grid infrastructure by the digital layer, to turn it comply with the IoT paradigm. For this
to be possible, it is necessary to use emerging technologies such as 5G, cloud computing
and edge computing. In this context, the interoperability between legacy systems and
intelligent electronic devices (IED) used by the Smart Grid has become an important
issue, since each manufacturer can adopt a different standard, energy distributors already
have their systems consolidated and any change in this balance directly affects the system’s
infrastructure. Thus, the integration of legacy IEDs in a Smart Grid environment based on
IoT, was accomplished by using the components of the SG2IoT architecture, presented
in this work, which allowed the inclusion of multiple IEDs in a scalable and flexible
environment made possible by the SG-Cloud-IoT ecosystem. Also, an application for
monitoring IEDs using the FIWARE platform was used in order to validate the proposed
solution regarding the display of critical information, status of IEDs and other information
in real time. Finally, experiments were carried out to evaluate the performance of the
solution when subjected to various levels of stress caused by the increased inclusion of the
number of devices using legacy Smart Grid protocols, such as IEC 61850 and DNP3. |
