چکیده

Energy hubs represent a key concept in the integration of multiple energy carriers, allowing for efficient coordination of various energy sources, conversion technologies, and storage systems. However, the reliability of these complex systems remains a significant challenge due to uncertainties in renewable energy generation, load patterns, and potential component failures. This paper introduces a comprehensive framework for reliability assessment of energy hubs using advanced Monte Carlo simulation techniques. We propose a novel approach that combines traditional sequential Monte Carlo simulation with kernel density estimation (KDE) for more accurate representation of uncertainties in renewable energy resources and load demands. The framework additionally incorporates cyber-physical interdependencies by modeling both physical components and their supporting cyber infrastructure. Two detailed case studies demonstrate the effectiveness of the proposed methodology: (۱) a small-scale residential energy hub with solar photovoltaics, battery storage, and grid connection; and (۲) a large-scale multi-carrier energy hub serving a commercial district with diverse energy conversion technologies. Results indicate that conventional Gaussian-based uncertainty modeling significantly underestimates operational risks, with our KDE-based approach revealing up to ۵۶% higher expected operational costs and substantially greater variability in reliability metrics. The paper provides practical insights for energy hub designers and operators while offering a robust computational tool for reliability-oriented planning and operation of future energy systems.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
