摘要
中国电网内主要存在热电联产和纯凝式两种燃煤火电机组。笔者提出了经由用户侧的热泵进行负荷控制,在两种火电机组之间实现新型节能调度的方法。首先,将采暖负荷由位于终端用户侧的分布式热泵和热水式散热器共同承担。其次,分别考虑了采暖热水的传输距离和热泵的电力消费两个影响因素。然后,在原采暖总负荷和非采暖电力消费不变的情况下,但实际需要的计算边界条件却从两种火电机组的出口被外延到终端用户处,等效于建立了新的热水与电力负荷约束条件,进而获得了较好的节能效益。最后通过模拟计算,进一步分析比较了具有不同性能系数的分布式热泵和空间热负荷分布分别对节能调度效益的影响。
There are mainly two kinds of plants in China, i.e. coal-fired cogeneration and condensing plant. The authors propose an energy conservation dispatch between them, which is realized through space heating load control based on mass introduction of electric heat pumps （EHPs） on the users＇ side. Firstly, space heating service can be shared by heating radiators and EHPs through heating water or electricity as energy carriers. Secondly, the transmission distance of heating water and electricity consumption of EHPs for space heating are considered as the new variables. In addition, though the original space heating load and non-heating electricity load are kept same, the practical boundary conditions of space heating load and non-heating electricity load is expanded from the plants to the end users＇ side, which develops new constraints equivalently and results in the potential energy conservation dispatched. Finally through numerical simulation, the energy conservation is revealed to be affected by EHPs with various coefficient of performance （COP） and spatial distribution of space heating load.
