针对冷热电联供型微网中的负荷类型建立能量平衡约束条件。冷热电联供型多微网和主动配电网作为两个不同的利益主体，采用分布式建模方法，建立不同的经济优化目标，联络线电功率作为两者的耦合变量，等效为虚拟负荷和虚拟电源实现冷热电联供型多微网主动配电系统优化模型的并行求解。天津中新生态城的算例表明冷热电联供
型多微网主动配电系统优化经济调度是有效的，能够实现两个利益主体的经济最优。(The energy balance constraint conditions are established for the load types of CCHP. As two different stakeholders, the cold, heat and power co-generation multi-micro-grid and the active distribution network adopt the distributed modeling method to establish different economic optimization objectives. The tie-line power is the coupling variable of the two and is equivalent to the virtual load and the virtual power to realize the optimization model of the cold, heat and power co-generation multi-micro-grid active distribution system. Parallel solution. The example of Tianjin new China eco city shows the combined cooling heating and power system.)
