In response to the escalating energy crisis and related pollution problems verified worldwide, it is essential to assume new energy technologies that use renewable energy sources in an efficient and environmentally friendly manner. However, widespread implementation of these sources will be more attractive only if they operate together with energy storage technologies. Besides, a successful storage...
This paper investigates the problem of electromagnetic interference (EMI) generated into power converters used to correct the power factor (PFC). The topologies discussed in this paper are the boost converter, interleaved boost and dual boost. The paths traveled by differential mode (DM) noise and common mode (CM) noise are illustrated. An analysis of the inductor parasitic capacitance impact over...
The increasing market penetration of intermittent renewable resources - as a solution to green power energy production has been resulting in the development of several types of storage technologies, such as: PHS, CAES, Flywheel, and supercapacitors. However, the constant development of different types of batteries - both conventional and by flow - turns this type of storage system one of the most...
Topological reconfiguration corresponds to an important tool for planning and operation of electric power distribution systems. Considering the distribution operation planning, how much time one algorithm gets an alternative topological status for the system is not a matter of importance, since the main objective assumed involves: power losses reduction, enhancing the voltage profile and increasing...
In view of current and foreseeable energy shortage and environmental scenario, the exploitation of renewable energy sources offer great potential to satisfy the energy lack and to decrease the dependence on fossil fuel, also reducing global warming caused by CO2 emissions. However, widespread implementation of these sources will be more attractive only if they operate together with energy storage...
Presence of the distributed generation (DG) in electric systems can represent a significant impact on the operational characteristics of distribution networks. This paper presents a study aimed at the appropriate choice of parameters used in a multi-objective analysis considering the optimal DG placement. Thus, this paper develops a multi-objective approach to define qualitative and quantitative parameters...
