Special Issue Information

Dear Colleagues,

To improve the sustainability of electricity generation in our national power grids, there has been increasing effort toward the utilization of renewable energies. However, connecting renewable energies to our electrical grids is not a simple task, as many renewable energies pose problems, such as system power injection. In addition, with the vast majority of renewable technologies being unreliable regarding their power generation, renewable energy systems have brought additional challenges to researchers who are trying to utilize this technology, especially in small scale microgrids. Several of the issues of incorporating renewable technology into microgrids have been solved with the utilization of power converters, with the main challenge now being how to control such technology to optimize behaviour within the power system. Due to the increased sensitivity and variability of the supply voltage to these power converters in microgrid environments, the control of the systems has become ever more paramount—and ever more complex—in microgrid design.

Therefore, this Special Issue aims to present the most recent advances in power electronics, focusing on power electronic control in renewable energy systems within microgrids from the perspectives of theory, modelling, control, new converter topologies, and algorithms.

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

Power converter modelling for AC, DC, and AC–DC hybrid.
Power converters control for AC, DC, and AC–DC hybrid.
New topologies for power converters applied for renewable energies and microgrids.

Abstract

Effective control strategies are essential for optimizing wave energy production. While theoretical studies have explored various control approaches, experimental validation of these methods remains limited. This study proposes a damping adjustment method as a means to enable the experimental application of resistive control in wave energy systems. The system’s damping is adjusted through a variable electrical resistance coupled to the generator. A mathematical model is developed to capture the interaction between the wave energy converter, generator, and variable resistance. Experimental validation demonstrates a good fit between the experimental results and the mathematical model. Four different DC machines acting as generators are tested to evaluate the influence of the model’s parameters on control capability. Results indicate that DC machines with less internal resistance allow a wider range of damping and power adjustment by using external resistance. The proposed method shows promising results, emphasizing the significance of the DC machine parameters in achieving effective control over system variables. These findings contribute to the development of efficient and reliable control strategies for enhancing wave energy production at small scales. Full article
