Special Issue Information

Dear Colleagues,

The global transition to a sustainable future hinges on the integration of renewable energy technologies into power systems. However, an increasing number of problems are caused by the high penetration of renewable energy technologies in distribution systems and microgrids, such as demand and supply mismatch, grid-edge voltage fluctuations, and the low-inertia of inverter-dominated power systems. The integration of renewable energy technologies into distribution systems is a multifaceted challenge; therefore, interdisciplinary and innovative solutions are required for the transition to integrating renewable energy technologies into distribution systems that are more distributed, resilient, reliable, and efficient.

This Special Issue on “Advances in Integration of Renewable Energy Technologies and Distribution Systems” calls for state-of-the-art works on this promising research area, which aims to explore the most recent advances related to the theory, modeling, planning, operation, and control methods to facilitate renewable energy integration into distribution systems and microgrids.

Topics of interest for publication include, but are not limited to, the following:

  • Grid integration strategies: Novel approaches for integrating different renewable energy technologies such as solar, wind, hydro, and geothermal into distribution systems while ensuring grid stability and reliability.
  • Grid management and control: Advanced grid management and control algorithms that enable real-time decision making with intermittent renewable energy sources, such as decentralized/distributed and model-based/-free methods.
  • Grid resilience and reliability: Strategies on enhancing grid resilience and reliability by leveraging grid-forming/-following capabilities of renewable energy sources.
  • Grid hosting capacity improvements: Developing more accurate grid models and novel methods to assess and improve grid hosting capacity for renewable energy sources, considering factors like voltage stability and transient stability.
  • Distributed energy resources: Innovations in management and control of distributed renewables, such as advanced inverters, to enhance the penetration and efficiency of renewable energy sources.
  • Microgrids and energy storage systems: Investigation of microgrids and energy storage systems that facilitate the integration of renewable energy, such as optimal microgrid sizing, microgrid control, and energy storage energy management.
  • Smart grid technologies: Utilization of smart meters, sensors, communication networks, and data analytics to optimize grid operation and improve renewable forecasting.
  • Source network load storage collaboration technology: Investigate the collaborative and coordinated operation mechanisms among "source network load storage", such as multi-energy complementary technology, power dispatching technology, and cloud technology.
  • Power electronic technology: Control strategy of intelligent switch and protection equipment, the design of renewable energy inverters, and power electronic topologies.
  • High-voltage transmission technology and equipment: Covering the application, development trend, and technological innovation of HVDC transmission in the 'cross-regional and long-distance' transmission of new energy to alleviate the gap between regional power supply and demand.

Sub-synchronous oscillations (SSOs) induced by the interaction between doubly fed induction generators (DFIGs) and weak grids pose a critical threat to the grid-connected stability of DFIG-based wind power systems. In this paper, a dual-damping-term compensation filter based on the concept of motion-induced amplification (MIA), together with an optimized design method using a linear quadratic regulator (LQR), is applied to the DFIG system. The effectiveness of the proposed approach in suppressing DFIG shafting oscillations and mitigating grid-connected frequency coupling is verified, and the underlying mechanisms are thoroughly investigated. By establishing a shafting dynamics model for the DFIG and a frequency-coupled oscillation impedance model, this study focuses on revealing the differentiated impacts of the dual damping parameters (Zp and Zq) on system stability under two operating modes: maximum power point tracking (MPPT) and constant power operation. Stability analysis based on the generalized Nyquist criterion (GNC), together with time-domain simulations, demonstrates that coordinated optimization of the dual damping terms can effectively suppress shafting oscillations and frequency coupling, thereby significantly enhancing the grid-connected stability of DFIG systems.

Renewable natural gas is an innovative alternative fuel source that has the potential to integrate seamlessly into the current energy and fuel sector. In addition, growing concerns related to energy security and environmental impact are incentivizing the development of RNG technologies. In conjunction with this document, current technologies related to biogas conditioning and biogas upgrading were covered in a separate analysis deemed Part I. With the current technologies, however, issues such as compositional quality, combustion efficiency, and high operational costs still need to be addressed before RNG can reach its true capability in use. Recent innovations have focused on optimizing techniques and introducing new methods to maximize methane yield and purity while minimizing costs and energy consumption. This document, Part II, provides an overview of emerging technologies related to further biogas upgrading, such as cryogenics, methane enrichment, and hybrid treatments, aimed at increasing cleaned biogas purity. Processes in development are also discussed, including industrial lung, supersonic separation, chemical hydrogenation, hydrate formation, and various biological treatments. The benefits of these advancements are increased purity for the ability to pipeline renewable natural gas in existing infrastructure, help industries reach sustainability goals, and contribute to a more resilient energy system. Together, Parts I and II offer a comprehensive understanding of both current and future technological developments. Full article

Energy security is a growing societal and industrial concern that leads research and development toward more sustainable options. Biogas, a bio-alternative to conventional fuels, is a product generated from the anaerobic digestion of organic matter. This source of fuel production is more environmentally friendly compared to traditional fossil fuels, leading to a lower carbon footprint, higher air quality, and the promotion of a circular economy. Impurities of raw biogas, such as carbon dioxide, hydrogen sulfide, and other trace contaminants, make biogas conditioning necessary for most applications. In addition, biogas upgrading, technologies furthering biogas purity, is an important factor in the production of biomethane, a sustainable biofuel known more commonly as renewable natural gas (RNG). Diversifying fuel sources and providing energy sustainability while mitigating negative environmental effects makes RNG an attractive alternative to conventional natural gas. This document, Part I, provides an overview of current technologies related to biogas conditioning, such as sorption, oxidation, and biological treatments aimed at the removal of a wide variety of contaminants. Processes developed for biogas upgrading are also discussed, including physical/chemical absorption, pressure swing adsorption, and membrane separation. The focus of upgrading applies approaches in meeting a higher quality biofuel by further carbon dioxide exclusion to ease pipeline transport and increase combustion efficiency. These technologies present the core foundation of processes in the production of RNG; however, all face inherent challenges that deem further research and development a requirement for global adoption. The biggest challenges are either in the cost of reaching higher purities or the inability to do so without other operations. Thus, in conjunction with this document, emerging and developing technologies are provided in a separate analysis deemed Part II. Together, these documents offer a comprehensive understanding of current practices and growing technological developments. Full article
