摘　　要：本文建立了一种三联供与地源热泵耦合的综合能源系统。文章旨在根据建筑负荷、设备容量、能源价格的实际情况,寻找经济性最优的运行策略。最优化方法采用了数学规划中的线性规划法,根据系统中各个设备的性能特点,运用linprog函数和Matlab编程语言,建立了该综合能源系统经济性最优的数学模型,分析了冬夏典型日的优化运行策略,并对全年的运行情况进行了模拟计算,和常规的供能方式进行了比较,分析了为可再生能源的消纳做出的贡献。This paper establishes a comprehensive energy utilization system that is coupled a CCHP system with a ground source heat pump. The article aims to find an economically optimal operating strategy based on the actual conditions of building load.equipment capacity and energy price. The linear programming method in mathematical programming is adopted. According to the performance characteristics of each device in the system.the linprog function and Matlab programming language are used to establish the mathematical model of the optimal economic system. The optimization operation strategy of typical winter and summer days is analyzed.and the operation of the whole year is introduced. The comparison with the conventional energy supply methods is carried out.and the contribution to the consumption of renewable energy is analyzed.
