Special Issue Information

Dear Colleagues,

In the last decade, power networks have undergone significant changes, such as the widespread deployment of smart meters, the connection of electric vehicles to low-voltage networks, and the increasing penetration of power-converter-based renewable energy sources in both transmission and distribution networks.

However, the connection of electric vehicles or power-converter-based distributed generators to the grid can cause power quality problems including harmonics, voltage fluctuations and flicker, voltage dips, and voltage unbalance. The improvement of power quality is currently one of the most important challenges in power systems, and solving it will require changes from the network planning stage up to the real-time operation of the network.

The connection of power converters to electricity networks continues to increase both in distribution networks (e.g., smart grids) and in transmission networks (e.g., HVDC installations). Connecting power converters results in a high emission of harmonic components into power networks. In some cases, these harmonic emissions extend beyond the supraharmonic frequency range of 2–150 kHz, causing malfunction in other devices connected to the grid.

All of this underlines the importance of developing new techniques for the measurement and analysis of harmonics and power quality to adapt to the changes in power networks.

We are inviting submissions to a Special Issue of Energies on the subject of “Harmonics and Quality of Power” and related topics in the context of power quality. The contributions must be original and not previously published elsewhere. Reviews as well as survey papers addressing the new trends in the topics of the Special Issue are also welcome, and will be considered for publication. Topics of interest include, but are not limited to the following:

  • Power quality in smart grids: EV impact and interaction between customer devices and PLC meters.
  • Harmonics’ analysis, prediction, and propagation in power networks with high penetration of power electronics converters.
  • Harmonics interaction among PV inverters.
  • Power quality in HVDC systems.
  • Interharmonics and supra-harmonics in networks with distributed generation.
  • Mitigation of harmonics and power quality disturbances.
  • New PQ measurement techniques: Big data and real time automatic analysis.

The Performance of the BTB-VSC for Active Power Balancing, Reactive Power Compensation and Current Harmonic Filtering in the Interconnected Systems

Nowadays, the use of power converters to control active and reactive power in AC–AC grid-connected systems has increased. With respect to indirect AC–AC converters, the tendency is to enable the back-to-back (BTB) voltage source converter (VSC) as an active power filter (APF) to [...] Read more.
Nowadays, the use of power converters to control active and reactive power in AC–AC grid-connected systems has increased. With respect to indirect AC–AC converters, the tendency is to enable the back-to-back (BTB) voltage source converter (VSC) as an active power filter (APF) to compensate current harmonics. Most of the reported works use the BTB-VSC as an auxiliary topology that, combined with other topologies, is capable of active power regulation, reactive power compensation and current harmonic filtering. With the analysis presented in this work, the framework of the dynamics associated with the control loops is established and it is demonstrated that BTB-VSC can perform the three tasks for which, in the reviewed literature, at least two different topologies are reported. The proposed analysis works to support the performance criteria of the BTB-VSC when it executes the three control actions simultaneously and the total current harmonic distortion is reduced from 27.21% to 6.16% with the selected control strategy.
