Special Issue Information

Dear Colleagues,

Multidisciplinary and emerging technologies in the field of power electronics are contributing to high-power-density and high-efficiency converters for interfacing fundamental strands such as renewable energy sources, electric mobility, energy storage systems, and active conditioners into smart grids. The present and future perspectives of power electronics concerning these strands aim to reduce the impact of climate changes and, at the same time, contribute to an equilibrium between sustainability and economic growth. This Special Issue aims to organize the present and future perspectives of power electronics in smart grids; therefore, original contributions are invited, including review papers, from different perspectives, including Ph.D. students, academic scientists, researchers, and professional communities. Potential topics of interest are related (but not limited) to the application of power electronics for the following:

Renewable energy sources and energy storage systems;
Electric mobility (e.g., G2V and V2G modes) and energy efficiency in transportation;
HVDC, SVC, and FACTS technologies;
Active power filters, hybrid power filters, and unified power quality conditioners;
Power quality, reliability, and security;
Unified topologies for power flow control in smart grids, microgrids, and smart homes;
Energy control and decisions and demand responses;
Energy and industrial, commercial, and residential applications;
Smart building technologies;
Technology and innovation for railways;
Fault-tolerant power electronic systems;
New semiconductor power devices (e.g., SiC and GaN) employed in power electronics;
New topologies of power electronics converters (e.g., multilevel and interleaved topologies);
New power theories and control strategies (e.g., model predictive and sliding mode).

Abstract

Power grids are progressing, and the possibility of incorporating DC grids toward hybrid AC/DC grids is gaining increasing relevance, as several technologies available nowadays are operating natively in DC. This paper proposes a topology of a full-controlled bidirectional dual-stage interleaved converter for interfacing hybrid AC/DC grids. The topology is based on a dual-stage architecture, constituted by an AC/DC converter and by a DC/DC converter, both based on interleaved power converters. On the AC side, which is connected to the main AC power grid, the proposed dual-stage architecture operates with sinusoidal current in phase or phase opposition with the voltage, meaning a bidirectional operation. In addition, it has the possibility of interfacing with other AC loads, such as domestic electrical appliances, or with an AC microgrid. The DC link, formed by the AC/DC power stage, is interfaced with a DC power grid, which provides numerous advantages, e.g., for interfacing battery electric vehicles directly charged in DC, as well as other DC loads, such as renewable energy sources. The DC/DC power stage is considered for interfacing with an energy storage system, which is capable of bidirectional power exchange with the DC grid or with the AC grid through the AC/DC power stage. A complete laboratory prototype was designed and developed, with the unified control algorithms implemented on a digital signal processor. The experimental results validated the operation of the full-controlled bidirectional dual-stage interleaved converter based on the specifications for the hybrid AC/DC grid, such as bidirectional operation, synchronization with the AC power grid, predictive current control, interleaved operation on both AC/DC and DC/DC power stages, DC-link voltage control for the DC grid, as well as the operation with different power levels.
