【摘要】 通过分析中国能源结构现状与能源转型面临的主要挑战，结合未来能源需求，研究适合中国国情的低碳、低成本的能源转型现实路径，提出以可再生能源为主体、多能源互补、“冷热电”联供、集“源网荷”于一体的新型能源系统解决方案——可再生能源综合系统；然后对可再生能源综合系统的现状与关键技术进行了研究，并分析了其未来发展趋势。研究结果表明：围绕用户侧构建分层次、分场景的以可再生能源为主体的集“冷热电”“源网荷”于一体的新型能源系统，是中国实现能源转型的系统解决方案。更多还原

【Abstract】 This paper analyzes the present situation of China’s energy structure and the main challenges faced by energy transformation,combined with future energy demand,and studies a low-carbon and low-cost energy transformation path suitable for China’s national conditions. It proposes a new type energy system solution that focuses on renewable energy as the main body,complements multi energy sources,combines "coolingheating-power",and integrates "source-network-load",which is a renewable energy integrated system. Then,the current status and key technologies of renewable energy integrated systems are studied,and their future development trends are analyzed. The research results show that building a hierarchical and scenario based new type energy system centered around the user side,with renewable energy as the main body,integrates "coolingheating-power" and "source-network-load" around the user side is a systematic solution for China to achieve energy transformation.更多还原
