Special Issue Information

Dear Colleagues,

The number of interconnected PV systems on the grid has been growing steadily in recent years. The contribution to low carbon electricity generation is desirable; however, the influx necessitates determination of its impact on the power quality of distribution networks. Issues such as voltage profile variation and harmonic distortion have been identified. A further understanding of potential issues and the influence on the network power quality is thus necessary.

This Special Issue welcomes original theoretical and practical contributions along with review papers on various aspects of power quality related to grid-connected PV systems. Topics include but are not limited to:

  • Representation of power quality characteristics in PV system software models;
  • Improved power converter topologies and modulation strategies for mitigation of power quality issues;
  • Advanced PV system control structures and their tuning for mitigation of power quality effects;
  • Impact on distribution networks’ power quality indicators from the integration of PV systems;
  • Effect of network connection and capacity on the interaction of PV systems with the network;
  • Integrated PV and energy storage systems and their impact on the voltage profile variation;
  • Monitoring and analysis of power quality effects arising from grid-connected PV systems;
  • Advanced measurements and signal processing techniques to detect power quality in the presence of PV systems;
  • Electromagnetic interference in PV systems.

In this paper, a direct power predictive controller (DPPC) is derived for a current source inverter (CSI) based single stage photovoltaic (PV) system. The equations of the dynamics, including AC and DC filters, are formulated directly for the PV power and for the active and reactive power injected in the grid. Then, the prediction equations are synthesized straight for the power, and, at each time instant, the optimal switching vector that guarantees simultaneously the control of the power generated by the PV arrays, and the control of the reactive power in the connection to the grid is chosen. This approach aims to guarantee fast and accurate tracking of the power. The proposed system is then validated through simulation and experimental results, showing that the PV system is able to follow the power references, guaranteeing a fast response to a step in the power, and decoupled active and reactive power control, with minimum total harmonic distortion (<5%) of the currents injected in the grid.
