Special Issue Information

Dear Colleagues,

The transformation of energy systems and infrastructure is accelerating due to increasing demands for sustainability, resilience, and digitalization. This Special Issue focuses on the intelligent design, optimization, and integration of distributed energy systems (DESs) and smart infrastructure, aiming to address the challenges and opportunities associated with decentralized power generation, multi-energy coordination, and smart urban environments.

The purpose of this issue is to synthesize innovative research on data-driven modeling, AI-enabled decision-making, real-time optimization, and cyber–physical system integration in energy systems. We welcome contributions that explore novel algorithms, tools, and frameworks that improve the planning, operation, and control of DESs and promote smart, efficient, and adaptive infrastructures.

This Special Issue is intended to supplement the existing literature by providing a holistic view of how intelligent technologies can enhance the interaction between energy systems and the broader built environment. It will emphasize interdisciplinary approaches involving electrical engineering, control theory, data science, and civil infrastructure, thereby encouraging collaborative research between academia and industry.

Topics of interest include, but are not limited to, intelligent energy management systems, distributed optimization, smart grid applications, multi-agent control, energy storage, infrastructure resilience, and digital twin technology in smart cities.

With the increasing integration of renewable energy sources into the grid, power quality at the point of common coupling (PCC)—particularly harmonic distortion introduced by power electronic converters—has become a critical concern. This paper presents a rigorous design and evaluation of a three-phase, fifteen-level cascaded H-bridge multilevel inverter (CHB MLI) with an LCL filter, selected for its superior harmonic attenuation, compact size, and cost-effectiveness compared to conventional passive filters. The proposed system employs Phase-Shifted Pulse Width Modulation (PS PWM) for balanced operation and low output distortion. A systematic, reproducible methodology is used to design the LCL filter, which is then tested across a wide range of switching frequencies (1–5 kHz) and grid impedance ratios (X/R = 2–9) in MATLAB/Simulink R2025a. Comprehensive simulations confirm that the filter effectively reduces both voltage and current total harmonic distortion (THD) to levels well below the 5% limit specified by IEEE 519, with optimal performance (0.53% current THD, 0.69% voltage THD) achieved at 3 kHz and X/R ≈ 5.6. The filter demonstrates robust performance regardless of grid conditions, making it a practical and scalable solution for modern renewable energy integration. These results, further supported by parametric validation and clear design guidelines, provide actionable insights for academic research and industrial deployment. Full article
