5. QoS management in smart grids: a Markovian approach
In Smart Grids, a variety of new applications are available to users of the electrical system (from consumers to the electric system operators and market operators). Some applications such as the SCADA systems, which control generators or substations, have consequences, for example, with a communication delay. The result of a failure to deliver a control mes

6. Distributed generators performance during short-circuits considering fault ride-through requirements / Desempenho de geradores distribuídos durante curtos-circuitos considerando requisitos de suportabilidade a afundamentos de tensão = : Distributed generators performance during short-circuits considering fault ride-through requirements
The increase of distributed generation penetration in distribution systems not only helps to diversify the electrical matrix but also brings both technical and economic benefits. Yet, it also raises worries related to energy supply reliability. For wind power plants into the medium and high voltage networks there are the grid codes for "Fault Ride-Through" w
