Double-unit coupling peak shaving method and device based on electricity and heat load cooperative scheduling of whole plant

The invention discloses a double-unit coupling peak shaving method and device based on electricity and heat load cooperative scheduling of a whole plant, and belongs to the technical field of cogeneration and thermal power flexibility. The device includes a first thermoelectric unit, a second thermoelectric unit, a first cooling steam system and a second cooling steam system. According to the method and the device, peak-shaving operation strategies of the two units are generated on the premise of meeting an external heat supply load requirement, not only the civil heating requirement is met, but also economic benefits of the peak-shaving operation of the whole plant are maximized, the design of the device is reasonable, the structure is simple, and performance is reliable. 本发明公开了一种基于全厂电、热负荷协同调度的双机组耦合调峰方法及装置，属于热电联产、火电灵活性技术领域，装置包括第一热电机组、第二热电机组、第一冷却蒸汽系统和第二冷却蒸汽系统。本发明是在保证外界供热负荷需求的前提下，进行两台机组调峰运行策略的制定，既保障了民生采暖需求，又实现了全厂调峰运行的经济效益最大化，其设计合理，结构简单，性能可靠。
