Special Issue Information

Dear Colleagues,

I am inviting submissions to this Special Issue of Energies on “Advanced Technologies in Power Quality and Solutions—2nd Edition”. In recent years, power electronics have been increasingly used in various fields, such as adjustable speed drives (ASDs), high-voltage direct-current (HVDC) systems, renewable distributed generation, electric vehicle chargers, furnaces, industrial manufacturing, domestic appliances, etc., which are nonlinear and cause impact loads, possibly resulting in not only power quality problems (e.g., harmonic distortion, poor power factor, and three-phase unbalance), but also excessive neutral currents, a lower system efficiency, disturbance to the consumers, and interference in nearby communication. As a dynamic and adjustable solution to these problems, power quality controllers have attracted the attention of many researchers. Power quality controllers can eliminate harmonics, compensate for the reactive power, correct the power factor, and solve the problems of voltage sag, swell and three-phase unbalance. The prospective authors are invited to submit original unpublished manuscripts addressing power quality.

This Special Issue will deal with advanced technologies in power quality. The topics of interest for publication include, but are not limited to:

  • Power Quality Analysis;
  • Power Quality Mitigation Technologies;
  • Power Quality Monitoring;
  • Power Quality Standards;
  • Equipment Power Quality Immunity;
  • Power Quality and Reliability;
  • Power Quality Data Analytics;
  • Distributed Generation and Power Quality;
  • Detection Technology of Power Quality;
  • Topology Structure of Power Quality Controllers;
  • Control Method of Power Quality Controllers;
  • Compensation Strategy of Power Quality Controllers;
  • Power Quality Problems in Power-Electronics-Based Power Systems;
  • Broadband oscillation and its suppression methods;
  • Disaster prevention and reduction in power systems.

The integration of converter facilities into power systems has warranted a growing need to address the control interference phenomenon. In this study, we propose a facility-based approach to mitigate the control interference between adjacent high-voltage direct current (HVDC) units in a multi-infeed HVDC system. The proposed method uses a series braking resistor (SeBR) as a preventive measure to restore control when a fault occurs in one HVDC unit within a multi-infeed HVDC system, thereby enabling stable operation of adjacent HVDC units. The developed SeBR model incorporates an inductor component and is divided into Stages 1 and 2 to overcome the frequency reduction issue associated with the long-term deployment of conventional R-based SeBRs. Additionally, if the fault continues to affect the control of adjacent HVDC units despite the application of a blocking stage in the faulted HVDC unit, switch controller logic circuits are designed considering the deployment of Stage 2 of the proposed SeBR. The effectiveness of the proposed SeBR is validated based on the detailed modeling and verification of actual HVDC systems via a case study. The results validate the superior performance of the proposed SeBR over other methods in ensuring a continuous stable operation of the system. Full article

DC voltage is one of the important parameters of active power filters. Since the series hybrid active power filter does not withstand the fundamental voltage, it cannot absorb energy from the power grid, making it too difficult to control its DC voltage. In order to solve the DC voltage control problem, an improved control method for the series hybrid active power filter with magnetic flux compensation is proposed in this paper. In this improved method, the fundamental magnetic flux compensation coefficient is equal to 1, meeting the condition of fundamental magnetic flux compensation. This improved method does not rely on the precise detection and phase-locking of the fundamental voltage at the port of the series transformer. A phase-fixed active current component is generated directly by the inverter, enabling the active power filter (APF) to absorb active power from the power grid. Consequently, the active power absorbed by the APF from the power grid has a linear relationship with the active current component. Both simulation and experimentation verified the correctness and effectiveness of this proposed method. Full article
