Special Issue Information

Dear Colleagues,

The global transition toward sustainable energy systems has significantly accelerated the integration of renewable energy sources (RESs) such as solar, wind, and hydro into modern power grids and, while this shift offers substantial opportunities, it also introduces considerable challenges. Chief among these is the inherent variability and intermittency of RESs, which—when interfaced with the grid through power electronic converters—can compromise the stability and reliability of conventional power systems. Advanced power electronics are therefore essential as they enable flexible, efficient, and intelligent control of generation, storage, and consumption.

In this context, the power engineering community is undergoing a profound transformation in network design and operational practices, and researchers and practitioners around the world are actively developing novel system architectures, control strategies, and protection schemes to facilitate the seamless and efficient integration of renewables. These efforts span a wide range of disciplines, including advanced converter design, wide-bandgap semiconductor technologies, grid-forming control, and hybrid AC/DC systems.

This Special Issue presents a curated selection of cutting-edge research that reflects the latest academic and technological progress in this rapidly evolving field. The contributions encompass theoretical modeling, experimental validation, and system-level innovation, offering valuable insights into how power electronics can enhance the flexibility, resilience, and efficiency of future energy systems.

This Special Issue on “Advanced Power Electronics for Renewable Integration” invites you to submit papers on, but not limited to, the following topics of interest:

  • Power electronics for solar, wind, and hydropower systems;
  • Control of converters interfacing with battery storage, supercapacitors, fuel cells, and flywheels;

Game-Theoretic Perspectives on the Optimal Design and Control of Power Electronic Systems
by Nikolay Hinov
Energies 2026, 19(9), 2125; https://doi.org/10.3390/en19092125 - 28 Apr 2026
Abstract

Power electronic systems are often engineered through a sequential–iterative workflow in which hardware parameters are initially sized from steady-state, ripple, thermal, and electromagnetic-compatibility constraints, and controllers are subsequently tuned to satisfy dynamic and closed-loop performance requirements. While converters are inherently designed for closed-loop operation, increasing power density, uncertainty, and distributed interaction make the underlying design process resemble a strategic interplay among multiple decision-makers, including hardware designers, control algorithms, loads, disturbances, and manufacturing constraints. This paper develops a unifying game-theoretic perspective on the optimal design and control of power electronic systems. Classical concepts—such as robust control, worst-case design, droop-based load sharing, and tolerance allocation—are reinterpreted as equilibrium solutions of zero-sum, Stackelberg, non-cooperative, or cooperative games. Beyond a conceptual taxonomy, two illustrative simulation case studies are provided: (i) a Stackelberg hardware–controller co-design of a buck converter, demonstrating simultaneous passive-component reduction and improved transient performance relative to a conservative sequential design; and (ii) a droop-controlled parallel-converter example contrasting Nash and cooperative equilibria, explicitly quantifying trade-offs between bus-voltage regulation, current-sharing fairness, and conduction losses. By framing power electronic design and control as interacting strategic processes rather than isolated optimization stages, the paper aims to show that game theory can serve as a structured and practically interpretable framework for distributed and uncertainty-aware power electronic systems.

The transition toward new power systems requires enhanced operational flexibility, within which circulating fluidized bed (CFB) units exhibit considerable peak regulation potential. This study develops an economic optimization framework to evaluate the benefits of flexibility retrofits for CFB units operating in coordination with wind power. A representative integrated system consisting of two 300 MW CFB units and a 300 MW wind farm is analyzed to compare ramping capability enhancement, minimum load reduction, and their combined implementation. The results indicate that the combined retrofit delivers the highest overall economic benefit at the system level. Even under a highly fluctuating wind power scenario, the combined retrofit achieves complete wind power accommodation, demonstrating the effectiveness of coordinated flexibility expansion. The minimum load reduction retrofit and the ramping capability retrofit reduce wind curtailment by 81% and 13%, respectively. Moreover, the economic benefit achieved by the combined retrofit exceeds the aggregate benefit of the two independent measures by about 6%, indicating a synergistic interaction between ramping flexibility and minimum load reduction retrofit. For the studied system, minimum load reduction retrofit contributes substantially greater economic gains than ramping capability enhancement when applied individually. Sensitivity analysis further highlights the influence of coal prices and feed-in tariff structures on retrofit profitability. Compared with existing studies focusing primarily on conventional pulverized coal units, this work establishes a quantitative framework tailored to CFB-specific flexibility retrofits, providing practical support for power systems with high renewable penetration.

Simulation-Based Analysis of Polarization Effects on the Shielding Effectiveness of a Metal Enclosure with an Aperture Exposed to High-Power Subnanosecond Electromagnetic Pulse

Intentional high-power electromagnetic (EM) interference poses a serious threat to sensitive electronic systems and often manifests as ultra-wideband (UWB) sub- and nanosecond pulses. Metallic shielding enclosures with technological apertures are commonly used for protection; however, apertures enable electromagnetic coupling into the enclosure and limit shielding performance. While most existing studies focus on transient disturbances with durations exceeding the enclosure transit time, this work addresses an ultrashort high-power subnanosecond UWB plane-wave pulse whose duration is significantly shorter than the enclosure transit time, a regime that remains insufficiently explored. A time-domain numerical analysis is performed for a low-profile rectangular metallic enclosure with a front-wall aperture, focusing on internal EM field evolution, internal pulse formation, and polarization-dependent shielding effectiveness. Three-dimensional full-wave simulations were carried out using CST Microwave Studio over a 90 ns observation window. The results show that the incident pulse excites primary subnanosecond EM waves inside the enclosure, which subsequently generate secondary waves through multiple reflections from the enclosure walls. Their interaction produces complex, long-lasting, time-varying internal field patterns. Although attenuated, the resulting internal subnanosecond pulses repeatedly traverse the enclosure interior, forming a pulse train-like sequence that may pose a cumulative electromagnetic threat to internal electronics. A key contribution of this work is the quantification of time-dependent local shielding effectiveness for both electric and magnetic fields, derived directly from the internal pulse train-like series obtained in the time domain. The concept of local, time-dependent shielding effectiveness provides physical insight that cannot be obtained from a single globally averaged SE value. In the case of ultrashort electromagnetic pulse excitation, the internal field response of an enclosure is strongly non-stationary and highly non-uniform in space, with local field maxima occurring at specific times and locations despite good average shielding performance. Time-dependent local SE enables identification of worst-case temporal conditions, repeated high-amplitude internal exposures, and critical regions inside the enclosure where shielding is significantly weaker than suggested by global metrics. Therefore, while conventional SE remains useful as a summary measurand, local time-dependent SE is essential for assessing the actual electromagnetic risk to sensitive electronics under ultrashort pulse disturbances. In addition, a global shielding effectiveness metric mapped over selected enclosure cross-sections is introduced to enable rapid visual assessment of shielding performance. The analysis demonstrates a strong dependence of internal wave propagation, internal pulse formation, and both local and global shielding effectiveness on the polarization of the incident subnanosecond EM pulse. These findings provide new physical insight into aperture coupling and shielding behavior in the ultrashort-pulse regime and offer practical guidance for the assessment and design of compact shielding enclosures exposed to high-power UWB EM threats.

With the increasing penetration of converter-based devices, harmonic distortion has become a major challenge for power quality monitoring in large-scale power systems. This study presents a systematic review of methods for modeling harmonic sources and their applicability to real-time monitoring of power distribution systems. The review was conducted following PRISMA guidelines, considering literature published between 2000 and 2026. Searches were performed across Scopus, IEEE Xplore, Web of Science, ScienceDirect, and MDPI using predefined keywords. A total of 128 peer-reviewed journal articles were included. Potential sources of bias were qualitatively assessed, including selection, retrieval, and classification bias; however, residual bias may still arise from database selection, keyword design, and study classification. A structured comparative framework is introduced, based on a six-dimension coverage scoring scheme and maturity analysis, enabling consistent evaluation across both methodological and deployment aspects. The robustness of this framework was evaluated using leave-one-out and perturbation analyses, indicating low variability in coverage scores and stable rankings across both corpora. A taxonomy of harmonic source modeling approaches is proposed. Comparative synthesis indicates that measurement-based approaches, particularly those leveraging distribution-level PMUs, show strong potential for real-time monitoring. Key challenges include D-PMU placement, data integration, and computational scalability. Future work should focus on physics-informed AI and digital twin-based monitoring. Full article
