This paper proposes an approach for optimal restoration of radial power distribution networks after an incident. This complex problem requires a decision-making process whose combinatorial nature can avoid the assessment of all possible solutions. Thus, the proposed approach is based on a binary coding particle swarm optimization (PSO) tool for handling the discrete variables associated with the switching...
This paper proposes the use of a three-phase high-frequency semicontrolled rectifier for wind energy conversion systems based on permanent magnet generators. The main advantages of the topology are: simplicity, since all active switches are connected to a common point, robustness, as short-circuit through a leg is not possible, and high efficiency due to reduced number of elements. As a disadvantage,...
The use of multilevel converters is widespread in medium-voltage applications due to their inherent capability to share the voltage between the power devices. More than one multilevel topology can be combined to form a single Hybrid Converter with improved capabilities. In particular, the series connection of a neutral point clamped (NPC) as a main inverter, providing the active power, and a floating...
