Special Issue Information

Dear Colleagues,

We are pleased to invite you to contribute with original research to this Special Issue “Symmetry in Energy Systems and Electrical Power”, where the principles of symmetry and asymmetry are used to improve the efficiency, sustainability, and reliability of energy systems in an individual manner or considering their interaction in the form of grids and microgrids. The aim of this Special Issue is to find ways to improve the synthesis, design, and performance of such systems by reducing losses and, thus, increasing efficiencies, which will be reflected in the use of less resources, less emissions to the environment, and a more stable performance of the system.

Dr. Sergio Cano-Andrade

Accurate voltage information is important for ensuring the safe operation of power systems and their performance evaluation. However, as distributed energy sources become more prevalent, the levels of harmonics and DC components in the power grid are increasing notably, resulting in voltage waveform distortion and a breakdown of waveform symmetry. As a result, traditional voltage parameter detection methods are unable to obtain the voltage information accurately. To address this issue, this paper proposed a novel approach that leverages adaptive estimation to accurately detect voltage parameters under grid voltage distortion conditions. More importantly, the proposed method has the ability to extract the harmonics and the DC component without steady-state error and exhibits a fast dynamic response. With this approach, the amplitude of the grid voltage can be derived in 4.2 ms when the grid voltage is undistorted. In the presence of low-order harmonics, the amplitude of the grid voltage can be accurately derived in 10.7 ms. Finally, simulation results and experimental results are respectively used for model validation and functionality validation. Full article
