Special Issue Information

Dear Colleagues,

We are inviting submissions to a Special Issue of Electronics in the subject area of “Power-Electronic-Based Smart Grid and Its Control Technology”.

The smart grid comprises an energy-generation, transmission, and distribution network and control units enhanced by digital control, monitoring, and telecommunications capabilities. Progress in power electronics technologies and modern control methods has enabled the smart grid towards new kinds of power-electronic-based grid operation, which can achieve almost all the needs of the smart grid for better power quality, reliability, and resilience. On the other hand, the high penetrations of power electronics converters and renewable energy in smart grids complicate the control process, e.g., addressing low inertia and lower stability issues. Thus, this Special Issue focuses on power-electronic-based smart grid, hybrid power systems with high-penetrated renewable energy and energy storage systems, stability analysis, and control technology for a sustainable future. Prospective authors are invited to submit original contributions or survey papers for publication in Electronics. Topics of interest for this Special Issue include, but are not limited to, the following topics in the field of power-electronic-based smart grid and its control technology:

  • Renewable energy and storage system integration;
  • Hybrid power supply systems;
  • Power-electronic-based smart grids;
  • Energy harvesting systems;
  • Advances in power converters and control technologies;
  • System stability analysis and optimization;
  • Frequency fluctuations and control strategies;
  • Dynamics power distribution technology;
  • Reactive power compensation.

Power systems with a high proportion of inverter-based sources like photovoltaics require a substantial short-circuit current ratio to ensure strong voltage support capabilities. However, this also increases the system’s short-circuit current capacity and levels, which may potentially affect the safe operation of system equipment and current-carrying conductors. To evaluate the operational risks, this paper proposes a quantitative calculation model for the critical integration proportion of grid-connected inverter-interfaced power sources based on short-circuit current over-limit probability. Firstly, according to the verification criterion about short-circuit current during the selection of the switching equipment and conductors in the power system, the short-circuit current over-limit probability evaluation system with five indices is established. Secondly, considering the impact of the increased grid integration proportion of inverter-based power sources on short-circuit currents, an evaluation process for operational risk probabilities is proposed. Based on this, the critical access proportion for inverter-based power source integration in the power grid can be calculated. Finally, the proposed model is used to assess the operational risk probability for a 220 kV system which includes a high proportion of inverter-based power sources in the Anhui area, China. Through the analysis of cumulative probability distribution curves, the critical grid integration proportion interval for the transition from normal to high proportion stages of inverter-based power sources is determined.
