Special Issue Information

Dear Colleagues,

This Special Issue of Sustainability will be focused on the current and future role of electronic power converters applied to renewable energy systems. Global energy demand will continue to grow at a considerable rate in the coming years. In this scenario, we are facing the challenge of continuing to produce energy and to support global growth while at the same time driving an energy transition towards non-fossil-based generation systems. Meeting this challenge will undoubtedly require the participation of renewable energies in any of its forms. In this energy scenario, power electronics becomes a strategic technology to achieve a high introduction of renewable energies, ensuring the sustainability of energy growth. The objectives of this Special Issue are aimed at the treatment of topologies, structures, and control systems of electronic power converters focused on the production, distribution, and efficient consumption of electrical energy produced from renewable sources.

The Guest Editors invite you to introduce original proposals for this Special Issue in Sustainability, on the theme of applications of electronic power converters in renewable energy equipment. Topics of interest include, but are not limited to, the following:

  • Advanced topologies of electronic power converters applied to renewable energy systems.
  • Advanced control techniques for electronic power converters in renewable energy sources.
  • Techniques for controlling the injection of energy into the grid from renewable energy sources.
  • Application of power electronics based storage devices for renewable energy resources.
  • Faults and diagnosis systems in power converters applied to renewable energy systems.
  • Real-time simulation of renewable energy generation systems.

In this paper, a power flow control strategy (PFCS) for the decentralized control of DC microgrids (DCMGs) is proposed to enhance the flexibility and scalability of the microgrid power system. The proposed scheme is achieved by combining the droop control and DC-link voltage control with the consideration of the electricity price condition. Generally, the droop control method can be used effectively in decentralized DCMGs to achieve power-sharing without additional communication links. However, the deviation of the DC-link voltage caused by the droop control affects the amount of power delivered to the load. As an alternative, the DC-link voltage control can be used to prevent such a deviation. To combine both control schemes in this study, the utility grid (UG) unit uses the DC-link voltage control to exchange the power between the DC-link and a UG in the grid-connected mode, while a distributed generator (DG) and energy storage system (ESS) units use the droop control method in the islanded mode. The operating modes of the UG, DG, ESS, and load units are determined by the deviation values of the DC-link voltage to maintain DCMG power balance. The overall PFCS is also developed for a decentralized DCMG system by taking into consideration several uncertainties such as DG power variation, battery state of charge (SOC) level, load demand, and grid availability. The proposed PFCS also considers electricity price conditions to adaptively change the DC-link voltage level for the purpose of minimizing the utility cost. When the DC-link voltage level is reduced due to the high electricity price condition, the proposed droop controller is designed such that the ESS unit operates with a discharging mode, which leads to the required minimum power support from the UG. The effectiveness of the proposed PFCS is demonstrated by comprehensive simulation and experimental results under various conditions. Those test results clearly confirm the control flexibility and overall performance of the proposed PFCS for a decentralized DCMG system. Full article
