Special Issue Information

Dear Colleagues,

The growing demand for sustainable energy solutions is driving rapid advancements in renewable energy sources (RESs) and energy storage system (ESS) technologies. Central to these advancements are power electronic converters, which play a critical role in ensuring efficient, stable, and reliable energy conversion between RESs, ESSs, and the grid. This Special Issue, “Power Converters for Renewable Energy Integration and Energy Storage Systems”, aims to bring together innovative research and insights into the design, optimization, and application of power converters in these evolving energy landscapes.

Specifically, this Special Issue focuses on innovative power electronic converters which play a pivotal role in integrating renewable energy sources such as solar, wind, and hydropower with energy storage systems, including second-life batteries, supercapacitors, and other emerging technologies. The Issue will delve into grid applications and fast-charging infrastructures for electric vehicles (EVs), both of which require highly efficient and scalable power converter technologies to integrate RESs and ESSs, particularly as the transition to clean energy accelerates. These converters are critical for managing energy flow while maintaining grid reliability and stability. Furthermore, modern power grids rely on converters that can operate in grid-feeding (injecting specific active/reactive power), grid-supporting (providing ancillary services), and grid-forming (establishing voltage and frequency) modes, depending on the needs of system operators. The Issue will cover a broad range of converter technologies, including DC–DC, AC–DC, DC–AC, and multi-level converters, as well as novel topologies and control strategies designed to enhance system efficiency, performance, and reliability. The scope of this collection encompasses both theoretical and practical research contributions that advance the understanding and application of power converters in energy systems.

Researchers and experts in the field are encouraged to submit their original research contributions, survey papers, or tutorials for review in this Special Issue. Topics of interest include but are not limited to the following:

  • Novel converter topologies for RES and ESS integration;
  • Innovative control strategies for power converters integrating RESs and ESSs;
  • Grid-feeding, grid-supporting, and grid-forming power converters with distributed resources;
  • Power converters for fast-charging infrastructures in electric vehicles;
  • High-efficiency converter designs for distributed generation;
  • Harmonic and power-quality improvements in energy systems;
  • Converter reliability and fault tolerance;
  • Power converters’ roles in enhancing the stability and flexibility of the grid.

The rapid integration of renewable energy and electric vehicles is challenging modern distribution networks with increased demand volatility and overload risks. To address these issues, we propose an integrated, multi-timescale battery dispatch framework that unifies long-term capacity planning, day-ahead/intra-day scheduling, and sub-minute real-time control. The framework combines HOMER Pro-based capacity sizing, a MISOCP model for economic scheduling, and an agent-based simulation for immediate overload mitigation. In a case study of a Danish distribution network projected to reach full EV penetration by 2034, our approach reduced moderate-to-severe overload incidents by 82.7%. Furthermore, a price-sensitive variant achieved a 27.4% reduction in operational costs, with only a 12.5% increase in minor overload events. These quantitative improvements, alongside qualitative enhancements in grid stability and battery longevity, provide actionable insights for distribution system operators. Full article

This paper presents a controller for a direct current (DC) grid-connected single-stage solar photovoltaic (PV) converter. The proposed controller provides both static and dynamic voltage support to the grid voltage. Unlike the common practice, it allows a small and controlled offset in the PV voltage in proportion to the power flowing through the converter, which enhances the system’s stability margins. A novel feedback branch from the grid voltage is introduced to enable grid voltage support. Additionally, the controller includes a current-limiting feature to protect the converter switches from overcurrent transients. The proposed approach combines and designs the voltage and current controllers using an optimal full-state feedback approach. This results in a systematic design with optimal and robust properties. Detailed simulations, comparisons, and experimental results are presented in this paper to verify the effectiveness of the proposed approach. Particularly, the experimental findings demonstrate improved stability during local load disturbances and grid fluctuations, with lower voltage drops, reduced grid current variations, lower stress on the grid, and reduced losses in the grid network compared to conventional controllers.
