针对实时发电计划应用模块上线后，如何与自动发电控制衔接以进一步提高调度运行精益化水平的问题，提出实时发电计划中的机组控制模式及其转换机制，建立了实时发电计划与自动发电闭环控制优化模型。模型根据控制模式的不同将机组分为自动发电控制机组、缓冲机组和计划机组3类，分别对不同控制模式的机组进行建模，可实现自动发电控制机组与缓冲机组控制模式的动态转换，同时将系统可调容量在不同类型机组间进行动态转移，达到可调容量合理分布的效果。采用IEEE 118节点系统对所提模型进行测试，结果验证了所提模型的可行性与有效性，表明实时发电计划编制时，通过兼顾自动发电控制需求，可以合理地在机组间分配系统可调容量资源，降低自动发电控制的运行压力，实现对控制资源的有效利用。

In allusion to link up the post-online application modules for real-time generation scheduling with automatic generation control (AGC) system to further improve the precision level of scheduling operation, a unit control mode in real-time generation scheduling and its transformational mechanism are proposed and a optimization model of real-time generation scheduling and closed-loop control of AGC system is established. In the established model, according to the differences of control modes generation units are divided into three categories, namely the AGC units, the transitional units and the scheduling units, and the modelings of the units belonging to different control modes are performed to implement the dynamic transformation between AGC units and transitional units, meanwhile, the dynamic transferring of regulable capacity of power system among different categories of generation units can reach the effect of reasonable distribution of regulable capacity. Using IEEE 118-bus system to test the proposed model, simulation results show that the established model is feasible and effective, and it is also indicated that during the drafting of real-time generation scheduling, by means of considering the demand of AGC the resource of regulable capacity of power system can be reasonably allocated among generation units to decrease the pressure of AGC during its operation and implement the effective utilization of the controlled resource.
