Advanced communication and information technologies enable smart grids to be more intelligent and automated, although many security issues are emerging. Security situational awareness (SSA) has been envisioned as a potential ...

This study presents a methodology to improve the operation of the power system and to deal with technical issues caused by electric vehicles (EVs) fast charging load. Fast charging stations (FCSs) are indispensable for ...

The radier foundation is a shallow foundation with little consideration in Brazil, on the other hand, this foundation is commonly the first option to be evaluated in several countries. Thus, there is little dissemination ...

This doctoral dissertation presents contributions related to transformerless grid-connected three-phase photovoltaic systems, focusing on the leakage current reduction. Among the leakage current reduction techniques, the ...

This work presents a study involving the construction and repowering of Transmission Lines with the installation of composite core aluminum conductors (Aluminum Conductor Composite Core – ACCC) and their performance compared ...

The electrical energy generation increases necessity to supply the countries demands, affected by the energy cost utilization, that invariably is generated several kilometers away from huge demanders centers, leads for a ...

Demand Response (DR) programs play a pivotal role in managing the balance of energy supply and demand, particularly in the era of expanding Renewable Energy Resources (RES) integration into the smart grid. By encouraging ...

The problem of autonomous robot navigation in internal environments must overcome various difficulties such as the dimensionality of the data, the computational cost and the possible presence of mobile objects. This thesis ...
