Special Issue Information

Dear Colleagues,

We are delighted to announce this call for papers for a Special Issue in Energies (IF 3.0).

With the increasing power demand and energy transition to a sustainable and decarbonized society, research activities and adoption of smart electric power systems have been brought to the fore.

The aim of this Special Issue, Advances in Research and Practice of Smart Electric Power Systems: 2nd Edition is to publish studies that reveal a wide range of real-world applications for hardware and software technologies in complex and data-driven power systems with distributed energy resources. This Special Issue aims to foster an extensive exchange of insights between the fields of energy production, transportation, end-uses, and utilization for pollution reduction and energy savings, thereby targeting carbon-neutral energy systems and green energy economies. Original research papers as well as review articles dealing with the most recent developments and innovations for the implementation of robust and flexible power and energy networks are also welcome.

Specific topics of interest include, but are not restricted to, the following:

  • Computing and communication technologies for smart grids;
  • Hardware and software approaches for smart/intelligent power systems;
  • Power grid planning and operations techniques for flexibility and resilience;
  • Energy efficiency improvement facilities for sustainable energy development;
  • Digital technology applications and services in the energy sector.

The increasing integration of resources with limited flexibility, such as solar power, electric vehicles (EVs), and other renewable energy sources, has raised significant concerns regarding power system stability. The stability of power systems is constantly threatened, particularly in cases where renewable energy is supplied to areas near generators, as transmission capacity constraints may lead to severe stability issues. The impact of renewable energy integration on system stability can be analyzed using transient stability and phase-angle stability theories. This study proposes a methodology to quantify the effects of renewable energy integration on transient stability. A power-phase angle curve is plotted using the Thevenin impedance calculation technique, and an improved equal-area method index is utilized to evaluate transient stability issues caused by renewable energy penetration. The proposed transient stability discrimination index (TSDI) is used to assess system stability in real-time conditions. Simulation results demonstrate that the proposed method achieves an accuracy of over 90% in ranking transient stability compared to conventional offline stability analysis. Furthermore, a correlation coefficient of 0.85 is observed between the proposed TSDI and the existing wide-area voltage stability index (WAVI), confirming the reliability of the method. These findings suggest that, when real-time Phasor Measurement Unit (PMU) data are available, the proposed approach can be effectively applied to practical power systems for enhanced stability assessment.

With the increasing adoption of renewable energy sources, such as solar and wind power, it is essential to achieve carbon neutrality. However, several shortcomings, including their intermittence, pose significant challenges to the stability of the electrical grid. This study explores hydrogen-based technologies, such as fuel cells and water electrolysis systems, as an effective solution to improve frequency stability and address the problems of power grid reliability. Using power system analysis programs, modeling and simulations performed on IEEE-25 Bus and Jeju Island systems demonstrate the potential of these technologies to mitigate reductions, reduce transmission constraints, and stabilize frequencies. The results show that hydrogen-based systems are important factors enabling sustainable energy transition. Full article
