論文概要:The increasing global energy demand, escalating concerns about climate change, and the depletion of fossil fuel reserves have necessitated the urgent development of sustainable and efficient energy systems. Distributed Energy Systems (DES) have emerged as a promising solution, offering localized, high-efficiency energy generation through poly-generation technologies. However, the large-scale implementation of DES faces significant challenges, including high initial investment costs, operational complexities, and the lack of comprehensive evaluation frameworks that balance economic, environmental, and technical considerations.

This study aims to address these challenges by proposing a novel DES model that integrates renewable energy sources such as photovoltaics, energy storage systems, and gas engines to optimize energy generation, distribution, and consumption. The proposed model focuses on maximizing grid stability and minimizing carbon emissions while ensuring economic feasibility. A multi-criteria evaluation framework was developed, incorporating key performance metrics, including cost-effectiveness, energy reliability, carbon footprint reduction, and adaptability to different scenarios.

To validate the proposed model, case studies were conducted under various application scenarios, including urban, industrial, and mixed-use environments. The results demonstrated that DES could significantly reduce peak energy demands, enhance self-sufficiency, and lower greenhouse gas emissions. Additionally, the findings reveal the economic viability of DES when properly configured, highlighting its potential to accelerate the transition to a sustainable energy future.

This research contributes to the existing body of knowledge by providing a robust methodology for DES optimization and performance evaluation. It offers practical insights for policymakers, energy planners, and industry stakeholders to facilitate the large-scale adoption of DES and shape energy policies that prioritize sustainability, resilience, and affordability. The study underscores the transformative potential of DES in achieving global energy sustainability and addressing pressing climate and energy challenges.
