Emerging Topics in Power Electronic Converters of Microgrids

Dear Colleagues,

Renewable energy (RE) prices have dropped significantly, making it possible for them to be included in microgrids, where now, power converters need to be adjusted in order to properly work under the conditions dictated by microgrids. The main issues of microgrids are due to the low inertia, lower stability, and the bidirectional energy flow, which entails variation on the voltage amplitude and/or frequency for AC or DC lines. Thus, the control of power converters may deal with these disturbances, help to increase the electric system stability, and transform the energy from REs to the network. In addition, the microgrid system’s power quality, reliability, and resilience are achieved by power converters and their respective control. In this context, other aspects need to be considered, such as energy production, power delivery, structure security, special policies, loads capacity to deal with variations on the power supply, and include different types of generators and a combination of them, such as solar, wind, heat, etc.

Thus, this Special Issue aims to present and disseminate the most recent advances in power electronics for microgrids in aspects such as theory, modelling, control, new topologies, and algorithms to make the microgrid system work.

The topics of interest for publication include, but are not limited to, the following:

• Power converter modelling for AC, DC, and AC–DC hybrid microgrids;
• Power converters control for AC, DC, and AC–DC hybrid microgrids;
• New topologies for power converters applied to microgrids;
• Grid integration through power electronics;
• Storage systems;
• Bidirectional DC/DC converters in DC microgrids;
• Renewable isolated microgrids;
• Power quality, reliability, and resilience;
• Trends in power converters;
• Predictive control for power converters in microgrids;
• Linear control for power converters in microgrids;
• Nonlinear control for power converters in microgrids;
• Green hydrogen systems;
• Trends in solar, wind, and marine energy power system;
• Electromobility and their impact on microgrids;
• Novel renewable energies and power topologies for microgrid applications.
