Special Issue Information

Dear Colleagues,

The Guest Editor is inviting submissions to a Special Issue of Energies in the subject area of “Advanced Technologies in Grid-Connected Inverters and Converters”. With the rapid growth of renewable power generation, grid-connected inverters and converters are playing an increasingly critical role in power and micro-grid systems. The conventional power system is evolving into a power electronics-enabled power system. Developments in power electronics-enabled power systems also create new challenges, such as novel power electronic topologies, modulation techniques, modeling and control of grid-connected inverters and converters. These emerging technologies will impose a critical effect on dynamic stability analysis, resilience and power equality enhancement of the grid-connected application.

This Special Issue will deal with novel power electronic topologies, modulation and control techniques, and different challenges in power electronics-enabled power systems, including microgrid systems, and so on. Particular topics of interest include, but are not limited to, the following:

  • Novel power electronic topologies of grid-connected applications;
  • Modulation techniques of grid-connected inverters and converters;
  • Modeling and control of grid-connected inverters and converters;
  • Dynamic stability analysis of grid-connected inverters and converters;
  • Approaches for resilience enhanced optimal operation methods of the grid-connected applications;
  • Schemes for power quality enhancement of the grid-connected applications.

Due to the voltage drop of the line impedance, power-transfer deviation occurs in the interlinking converter (IC) of hybrid microgrids. In this paper, an IC control strategy in hybrid microgrids is proposed, which can estimate the line resistance precisely. Moreover, the proposed method can easily realize accurate power transmission between sub-grids and maintain the power balance of hybrid microgrid. Firstly, one specified small signal is injected into the IC at the AC bus of the distributed generation so as to estimate the line impedance. The frequency of the injected small signal is highly relevant to the AC bus voltage. As a result, the IC can accurately detect its line impedance by extracting the injected small signal frequency with a filter and phase-lock-loop (PLL) without communication. Secondly, with the line impedance estimation, the voltage drop on the line can be compensated with local information of the IC, and consequently, accurate power transfer can be realized. Finally, the validity of the proposed method is verified by simulation and experiment results. Full article
