Special Issue Information

Dear Colleagues,

The continued growth of renewable energies and their integration to the power grids, especially through distributed integration, has increased the importance of electrical power control and management. In addition to distributed integration of the renewables, the increasing applications of the recent technology of light-emitting diodes (LEDs) and resultant power electronics have impacted power quality as well. As such, power quality analysis has an important role to play not just in power management but also in the final electrical power quality delivered to customers. This Special Issue invites researchers in the fields of power control and management, renewable power distribution, and power quality measuring and control to submit their quality research works for publication. The Special Issue includes but is not limited the following topics:

  • Renewable energy management;
  • Distributed power generation;
  • Power system control;
  • Power system generation planning;
  • Power system transmission planning;
  • Optimized power systems;
  • Optimization of the power system planning;
  • Electrical power quality measurement;
  • Power systems harmonics and inter-harmonics measurement;
  • Power system sub-harmonics measurement;
  • Supra-harmonics interference to electrical power.

Penetration of equipment such as photovoltaic power generations (PV), heat pump water heaters (HP), and electric vehicles (EV) introduces voltage unbalance issues in distribution systems. Controlling PV and energy storage system (ESS) outputs or coordinated EV charging are investigated for voltage unbalance compensation. However, some issues exist, such as dependency on installed capacity and fairness among consumers. Therefore, the ideal way to mitigate unbalanced voltages is to use grid-side equipment mainly. This paper proposes a voltage unbalance compensation based on optimal tap operation scheduling of three-phase individual controlled step voltage regulators (3ϕSVR) and load ratio control transformer (LRT). In the formulation of the optimization problem, multiple voltage unbalance metrics are comprehensively included. In addition, voltage deviations, network losses, and coordinated tap operations, which are typical issues in distribution systems, are considered. In order to investigate the mutual influence among voltage unbalance and other typical issues, various optimization problems are formulated, and then they are compared by numerical simulations. The results show that the proper operation of 3ϕSVRs and LRT effectively mitigates voltage unbalance. Furthermore, the results also show that voltage unbalances and other typical issues can be improved simultaneously with appropriate formulations. Full article
