The study of power systems is closely related with symmetry. For example, multiphase power systems are inherently symmetric. The study of symmetrical and asymmetrical faults in power systems is a critical issue. The phase sequence arrangements of multicircuit overhead lines on the same tower directly affects the symmetry of power transmission systems, which influence the operation of power grid and relay protection. Moreover, symmetry is a topic of intensive investigation in the analysis of grid interconnection, including symmetrical and asymmetrical network parameters in smart-grid infrastructures. In renewable energy, the symmetry is present in the layout of wind power plants or photovoltaic plants, among others, while solar systems can have a different performance if they are used with symmetric and asymmetric concentrating CPC collectors.
This Special Issue invites researchers to submit original research papers and review articles related to renewable energy and power systems in which theoretical or practical issues of symmetry are considered. Applied case studies are especially welcome. The topics of interest include but are not limited to:
- Symmetry in the topology of power grids;
- Symmetry in multiphase/polyphase power systems. Power network synchronization;
- Symmetric and asymmetric components;
- Symmetrical and asymetrical faults in power systems;
- Symmetry analysis of phase sequence arrangements of multicircuit overhead lines;
- Symmetry studies of electrical signals using signal processing methods (FFT, DFT, STFT, WT, etc.);
- Symmetry in power electronics devices and renewable energy components;
- Symmetry in renewable energy systems (including smart-grids and micro-grids);
- Symmetrical analysis of power plant layouts and location (including wind farms and photovoltaic plants);
- Algorithms for studying symmetry in renewable energy and power systems.

Abstract: Renewable energy today is no longer just an affordable alternative, but a requirement for mitigating global environmental problems such as climate change. Among renewable energies, the use of solar energy is one of the most widespread. Concentrating Solar Power (CSP), however, is not yet fully widespread despite having demonstrated great efficiency, both on a large scale and on a small scale for heating water in industry. One of the main drawbacks to this energy solution is the large size of the facilities. For this purpose, several models have been developed to avoid shadowing between the CSP arrays as much as possible. In this study, the classic shadowing models between the CSP lines are reviewed. Where one of the major challenges is that they are studied geometrically as a fixed installation, while they are moving facilities, as they have a tracking movement of the sun. In this work, a new model is proposed to avoid shadowing by considering the movement of the facilities, depending on their latitude. Secondly, the model is tested to an existing facility as a real case study located in southern Spain. Finally, the model is applied to the main existing installations in the northern hemisphere, thus showing the usefulness of the model for any CSP installation in the world.
