摘　　要：以多能协同综合能源系统的供暖用暖体系为研究对象,计及需求侧用户行为分析,提出综合供应侧与需求侧的优化方法。结合效用函数对需求侧用户用暖行为进行分析;根据不同能源的制暖特点建立供应侧经济性模型,根据不同能源的供暖机制建立需求侧经济性模型;以供应侧电厂运行效率最大、需求侧居民用电成本最低为目标进行双目标优化。将该优化方法在热电联产系统与电热气综合能源系统2种算例中进行分析并对比结果,证明了天然气系统的加入对综合能源系统具有协同优化作用,也验证了所提方法的有效性与可行性。With the heat supply and consumption system of an IES- MEC（Integrated Energy System with Multi-Energy Cooperation） as the research object,a method of comprehensive optimization including user behaviour analysis is proposed for its supply and demand sides. The utility function is adopted to analyze the user behaviour towards the heat consumption at demand side. The economic supply-side models are established according to their heat generation characteristics for different energy sources while the economic demand-side models according to their heat supply mechanisms. A bi-objective optimization method is suggested,which maximizes the operational efficiency of power plant at supply side and minimizes the household electricity consumption cost at demand side. The proposed method is respectively applied to a heat-power combination system and an electricity-heat-gas IES. The optimization results are analyzed and compared,which proves that the integrated gas system enhances the cooperative optimization effect of IES and also ver/fies the effectiveness and feasibility of the proposed method.
