Special Issue Information

Dear Colleagues,

The integration of renewable energy sources into microgrid systems is a pivotal step towards achieving a sustainable and reliable energy future. Power electronics play a central role in enabling the efficient, flexible, and resilient operation of microgrids and renewable energy systems. This Special Issue aims to compile cutting-edge research, innovative solutions, and practical applications of power electronics in microgrid and renewable energy systems.

The topics of interest for this Special Issue are as follows:

We invite contributions on a wide range of topics related to the application of power electronics in microgrids and renewable energy systems, including, but not limited to:

Advanced Inverters and Converters: Novel designs, control algorithms, and topologies for grid-tied and off-grid inverters and converters.

Energy Storage Systems: Integration of energy storage technologies (e.g., batteries, supercapacitors, hydrogen) with power electronics in microgrid systems.

Grid Integration: Strategies and technologies for the seamless integration of renewable energy sources into the grid, including grid-forming inverters.

Distributed Energy Resources (DERs): Control and coordination of DERs within microgrid systems for enhanced reliability and efficiency.

Microgrid Control and Management: Advanced control methods, optimization techniques, and real-time management of microgrid systems.

Harmonics and Power Quality: Mitigation of harmonics and improvement in power quality in microgrids and renewable energy systems.

Fault Detection and Diagnosis: Methods for fault detection, isolation, and diagnosis in power electronics components within microgrid systems.

Resilience and Reliability: Enhancing the resilience and reliability of microgrid systems, including fault-tolerant operation.

Grid-forming inverters, which are represented by droop control and virtual synchronous generator control, have been widely studied and applied because of their excellent grid-supporting ability and smooth off-grid switching. When a grid-forming inverter is connected to a microgrid or utility grid, the control loops of active power and reactive power will be coupled because of the voltage phase difference, which will affect the power control performance. This paper first derives the small-signal linearized model of the system, based on which a frequency feedforward control and an amplitude feedforward control are proposed to decouple the active power and reactive power control loops, respectively. The proposed decoupling strategy directly modifies the reference values through feedforward with an easily implementable principle that is applicable to various control coordinate systems, control coordinate systems, and control structures. By comparing system models with and without the proposed decoupling strategy, its effectiveness can be theoretically proven. Time-domain simulations and hardware experiments are presented to further validate its effectiveness. Full article
