Special Issue Information

Dear Colleagues,

The rapid transformation of modern power systems is being driven by the widespread deployment of power electronic-interfaced devices (PEDs), such as renewable energy sources (RESs), energy storage systems (ESSs), electric vehicles (EVs), and high-voltage direct current (HVDC) links. While these technologies have significantly improved the flexibility, sustainability, and efficiency of power systems, they have also introduced profound changes in system dynamics and stability characteristics.

With the reduction in system inertia, the increasing complexity of multi-source coordination, and the prevalence of nonlinear and multi-time-scale behaviors, ensuring the stability of power systems has become a major technical challenge. Conventional analytical tools and control schemes are no longer sufficient to cope with emerging issues such as wide-area oscillations, weak grid-induced instability, and high-frequency dynamic interactions among PEDs. Furthermore, unpredictable variations in generation and load profiles, especially prevalent in RESs and EVs, introduce additional uncertainty and necessitate more robust and adaptive control strategies.

To address these challenges, new insights into the mechanisms of instability and advanced control methodologies are urgently needed. Both model-based and data-driven approaches are being developed to analyze and mitigate various types of instability in modern and future power systems. These include nonlinear system modeling, multi-layer coordinated control, distributed and decentralized control frameworks, and AI-assisted decision-making systems, among others.

This Special Issue aims to provide a comprehensive platform for the dissemination of the latest research and development in the field of power system stability analysis and control. We invite researchers and industry professionals to contribute original articles and reviews that explore emerging techniques, theoretical advancements, and practical solutions related to power system stability.

Potential topics include, but are not limited to, the following:

  • Theoretical and practical methods for power system stability analysis;
  • Nonlinear dynamics and multi-time-scale modeling of power systems;
  • Control strategies for frequency and voltage stability in weak grids;
  • Coordinated control of converters in renewable-rich power systems;
  • Wide-area oscillation analysis and damping controller design;
  • Grid-forming and grid-following control interactions;
  • Robust and adaptive control of power electronic-interfaced systems;
  • Stability enhancement techniques for HVDC and FACTS applications;
  • Cooperative control of distributed energy resources;
  • Data-driven and AI-based methods for system stability assessment;
  • Energy storage strategies for transient- and steady-state stability support.

We look forward to receiving your contributions to this Special Issue, which will highlight ongoing efforts and future research directions in securing the stability of modern and future power systems.

The paper presents four solutions to the voltage source inverter (VSI) control system with existing delays in the measurement channels and the middle switching frequency (25,600 Hz): Single-Input Single-Output Coefficient Diagram Method (SISO-CDM), Multi-Input Multi-Output Passivity-Based Control (MISO-PBC), Multi-Input Multi-Output One-Sample-Ahead Preview Controller (MISO-OSAP), and MISO-OSAP with Luenberger Observer (MISO-OSAP-LO). The theory, including adjustments to controller gains or to the coefficients of the characteristic equation of the closed-loop system, is presented. Simulations of the VSI operation with these control systems for the nonlinear load and the dynamic resistive load (per the requirements of the EN 62040-3 standard) are presented. The SISO-CDM and MISO-PBC are finally selected for experimental verification of the simulations. The results of the tests enable the selection of the control type for a particular VSI design based on its cost and an estimation of the advantages of the more expensive solution. The paper should help in engineering design according to the remarks in the paper. Full article

The characteristics of the dynamic reactive power demand of a hybrid multi-infeed HVDC transmission system during the post-fault recovery period are analyzed and a coordinated control strategy to improve the fault recovery characteristics of the hybrid multi-infeed HVDC transmission system is proposed in this paper. During the process of fault recovery, the LCC-HVDC adopts a progressive staggering recovery strategy. At the same time, according to the reactive power shortage of LCC-HVDC, the dynamic power limiter is used to adjust the upper and lower limit values of the outer loop power controller of VSC-HVDC, and the reactive power generated by the VSC-HVDC can be rapidly adjusted. Therefore, the problem of excessive reactive power demand during the recovery process can be solved and the reactive power demand can be satisfied with the proposed strategy. Moreover, the ability of VSC-HVDC to provide reactive power support can be fully utilized. Finally, a simulation model of a hybrid tri-infeed HVDC system is built using PSCAD/EMTDC (Version 4.6.2) software to verify the effectiveness of the proposed control strategy. Full article
