摘　　要：由多种分布式能源组成的冷热电三联供系统,高效可靠,灵活性强,是一种节能环保的能源供应方式。以涵盖电、热、冷多个领域的分布式能源联供系统为对象,建立系统负荷协同高效生产和利用的优化调度模型,将考虑了一次能源消耗、环境补偿成本、运行维护费用的综合成本最低作为运行目标,采用非线性规划法,确定各分布式能源机组在给定负荷下的最佳出力值。算例结果表明,所建立的分布式冷热电三联供协同优化调度系统能够有效提高系统运行经济性和环保性,与传统调度模式相比,优化后24小时累计运行费用可降低32%,是实现节能减排、提高能源利用率的有效手段。In this paper,the distributed energy cogeneration system covering the fields of electricity,heat and cold is taken as the object,the optimal scheduling model of collaborative and efficient production and utilization of system load is constructed,taking the lowest economic cost which considers primary energy consumption,environmental compensation costs,operation and maintenance costs as the operating target,the nonlinear programming method is used to determine the optimal output value of each distributed energy unit under a given load.The simulation results show that the distributed CCHP coordinated optimization scheduling system can effectively improve the system operation economy and environmental protection,compared with the traditional dispatching mode,the cumulative operation cost of 24 hours after optimization can be reduced by 32%.
