摘　　要：在电热综合能源系统框架下从总的节能减排效益角度出发,以供电供热总化石能源消耗最小为目标,研究高比例可再生能源系统中各类电源的相互关联机理及能源资源优化配置问题。基于对各类电源、热源在供电、供热、煤耗和灵活性等方面的分析,建立了以化石能源消耗最少为目标的电源容量配比优化模型,并结合蒙西电网的实际数据进行计算分析。对当前电、热负荷水平下的电源容量最优配比及各类电源之间的相互关联关系进行了讨论,为可再生能源和常规电源的协调发展和节能减排效益最大化提供科学指导。The interrelationships among different energy sources and their optimal capacity ratios of the integrated electricity-heat energy system with high proportion of renewable energy sources are researched to minimize its total fossil energy consumption for energy saving and emission reduction. The performances of different electricity and heat sources are analyzed in the aspects of power supply,heat supply,coal consumption,flexibility,etc.,based on which,a capacity-ratio optimization model with the minimum fossil energy consumption as its objective is established. Case study is performed based on the actual data of West Inner Mongolia Power Grid. The optimal capacity ratios of different energy sources for present electricity and heat load levels and their interrelationships are discussed,which provides the scientific guidance for the coordinative development of renewable and conventional energy sources and the benefit maximization of energy saving and emission reduction.
