Special Issue Information

Dear Colleagues,

The integration of renewable energy sources into modern power systems plays a crucial role in ensuring global sustainable development. However, the intermittent and variable nature of renewables energy sources such as solar, wind, and tidal energy introduces significant challenges in terms of system stability, efficiency, and reliability. This Special Issue aims to gather cutting-edge research and recent advances in the field of optimization and control strategies for renewable energy and renewable energy-integrated systems.
We welcome original research articles, review papers, and innovative case studies that focus on optimization algorithms, intelligent control systems, real-time energy management, smart grid technologies, and hybrid renewable systems. Topics of interest also include predictive control, distributed energy resource management, machine/deep learning applications in control, energy storage optimization, and resilience strategies for power systems under high renewable deployment.
This Special Issue provides a platform for scholars and practitioners to present state-of-the-art developments and share knowledge that supports the transition toward clean and sustainable energy systems. We encourage submissions that bridge the gap between theory and real-world implementation, and particularly those that demonstrate tangible contributions to environmental quality and energy efficiency.
We look forward to your valuable contributions.

The significant increase in renewable energy sources and HVDC transmission has resulted in a substantial reduction in power system stability, thereby giving rise to a growing concern regarding the safety and stability of the voltage and frequency of DC power systems. A survey of the extant literature pertaining to both DC outgoing systems and new energy power systems reveals a preponderance of studies that employ the short-circuit ratio or multi-site short-circuit ratio as a metric for strength evaluation. However, it is evident that there is an absence of a universally applicable and comprehensive strength definition index for new energy and DC-accessed sending/receiving systems. Thus, the present paper puts forward a novel voltage stiffness-based strength evaluation index for new energy and DC-accessed sending/receiving systems and provides a qualitative analysis from the perspective of static voltage stability support. The static stability limit and transient overvoltage limit correspond to impedance ratios of 1 and 2.56, respectively. The findings demonstrate the efficacy of the proposed index in accurately gauging the strength of the sending system. The index’s versatility is further highlighted by its wide applicability in the sending/receiving systems of new energy and HVDC access. Full article
